==Photonicat SD/eMMC刷其他固件==
Photonicat可以通过自制烧录TF卡和通过USB线刷两种方式来刷新固件。
===自制烧录TF卡===
#下载TF卡镜像文件
#下载需要刷新的固件
#制作烧录TF卡
::'''Linux系统制作烧录TF卡'''
::#使用<code>gunzip -c TF卡镜像文件 | dd of=TF卡设备文件(例如: /dev/mmcblk0)</code> , gunzip用于解压缩gz后缀的压缩文件,如果已经解压缩无需这条指令，直接<code>dd if=TF卡镜像文件 of=TF卡设备文件(例如: /dev/mmcblk0)</code>
::#烧录TF卡完成后，挂载分区，例如：<code>mount /dev/mmcblk0p6 /mnt</code>
::#把需要更新的固件复制到挂载分区上，例如：<code>cp 固件 /mnt</code>
::#卸载分区，例如：<code>umount /mnt</code>
::'''Windows系统制作烧

录TF卡'''
::#使用Win32 Disk Imager烧录TF卡镜像文件
::#TF卡分区为ext4格式，Windows下不可操作，所以需要刷新的固件仍需要在Linux系统下参照'''Linux系统制作烧录TF卡'''操作步骤2~4操作
::TF卡插入Photonicat卡槽启动后手动烧录如下： <code>dd if=固件 of=emmc设备文件(例如: /dev/mmcblk1)</code>
===USB线刷===
#下载需要刷新的固件
#下载烧录软件
::'''Linux系统'''
::*软件URL
::'''Windows系统'''
::*软件URL
#打开烧录软件，选择升级固件这个Tab，然后点击固件选择相应的固件文件
#通过Photonicat按键方式进入烧录模式（参见'''按键功能定义表'''）
#使用两边都是标准USB公头的连接线连接Photonicat USB口和烧录用电脑的USB口（注意电脑USB口的供电能力，如供电能力不足会造成烧录失败）
#等待烧录软件显示'''发现一个Maskrom设备'''，然后点击升级
#右侧信息栏会显示烧录进度和状态，烧录成功后Photonicat会自动重启

</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2l.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2l/Image /mnt
cp -v linux-cip/deploy/g2l/r9a07g044l2-smarc.dtb /mnt
cp -v linux-cip/deploy/g2l/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 11 (Bullseye) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager bullseye "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2l/modules.tar.gz
tar -czpf ../debian-bullseye-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-bullseye-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-bullseye-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
run sdboot
</pre>
The device path of SD card is /dev/mmcblk1, and the path of eMMC is /dev/mmcblk0. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2l.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2l/Image /mnt
cp -v linux-cip/deploy/g2l/r9a07g044l2-smarc.dtb /mnt
cp -v linux-cip/deploy/g2l/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 11 (Bullseye) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager bullseye "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2l/modules.tar.gz
tar -czpf ../debian-bullseye-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-bullseye-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-bullseye-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
run sdboot
</pre>
The device path of SD card is /dev/mmcblk1, and the path of eMMC is /dev/mmcblk0. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

==Using GPIO==
{| class="wikitable"
|-
! GPIO Bank !! Address
|-
| GPIO 0 || 494
|-
| GPIO 1 || 471
|-
| GPIO 2 || 445
|-
| GPIO 3 || 429
|-
| GPIO 4 || 418
|-
| GPIO 5 || 398
|-
| GPIO 6 || 380
|}

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

alsactl store
</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

==Known problems==

===WiFi module does not support random MAC===
By default, Network Manager will use random MAC for better security, somehow the module used on this board does not support it. You should disable it by edit file <code>/etc/NetworkManager/NetworkManager.conf</code>, add add lines below:
<pre>
[device]
wifi.scan-rand-mac-address=no
</pre>

===Set MAC address of ethernet card===
There is no EEPROM or SPI Flash to save MAC address for ethernet card. So you can set MAC address by yourself. e.g. Using Network Manager:
<pre>
sudo nmtui
</pre>

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

===No Graphic Accelerations on Debian rootfs===
2D/3D Graphic Accelerations are only supported in Renesas's customized Yocto, and only Wayland is supported.

</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

==Using GPIO==
{| class="wikitable"
|-
! GPIO Bank !! Address
|-
| GPIO 0 || 494
|-
| GPIO 1 || 471
|-
| GPIO 2 || 445
|-
| GPIO 3 || 429
|-
| GPIO 4 || 418
|-
| GPIO 5 || 398
|-
| GPIO 6 || 380
|}

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

alsactl store
</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_2X8/640x480 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/640x480 field:none]"
</pre>

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

==Using GPIO==
{| class="wikitable"
|-
! GPIO Bank !! Address
|-
| GPIO 0 || 494
|-
| GPIO 1 || 471
|-
| GPIO 2 || 445
|-
| GPIO 3 || 429
|-
| GPIO 4 || 418
|-
| GPIO 5 || 398
|-
| GPIO 6 || 380
|}

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

alsactl store
</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_2X8/640x480 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/640x480 field:none]"
</pre>

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

==Known problems==

===WiFi module does not support random MAC===
By default, Network Manager will use random MAC for better security, somehow the module used on this board does not support it. You should disable it by edit file <code>/etc/NetworkManager/NetworkManager.conf</code>, add add lines below:
<pre>
[device]
wifi.scan-rand-mac-address=no
</pre>

===Set MAC address of ethernet card===
There is no EEPROM or SPI Flash to save MAC address for ethernet card. So you can set MAC address by yourself. e.g. Using Network Manager:
<pre>
sudo nmtui
</pre>

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

===No Graphic Accelerations on Debian rootfs===
2D/3D Graphic Accelerations are only supported in Renesas's customized Yocto, and only Wayland is supported.

===No Bayer Color Encoding Support===
Some cameras (like Sony IMX219) can only output RAW bayer video data, which is not supported by hardware encoders on the board. Even through you can convert color space with GStreamer element like bayer2rgb, it will cost lots of CPU resources and RAM bandwidth.
==Test==
===Enable Speaker Output===
<pre>
echo 393 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio393/direction
echo 1 > /sys/class/gpio/gpio393/value
gst-launch-1.0 audiotestsrc ! audioconvert ! audioresample ! autoaudiosink
</pre>
===Use Mic===
<pre>
arecord -Dhw:0,0 -f S16_LE -t wav -r44100 -c 2 record.wav
Note: not support sample rate 48000
</pre>
===RS485 Port===
<pre>
TTY： ttySC2
Note：
1. disable flow control
</pre>
===Enable Developer options in Android===
<pre>
Steps:
1. Find item "Buile number" (Path: Settings -> About tablet -> Build number)
2. click it 10 times
</pre>
===How to adb connect device through network===
<pre>
Debug console steps:
1. su
2. setprop service.adb.tcp.port 5555
3. stop adbd
4. start adbd
ADB connect command:
1. adb connect <Device IP>
</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

==Using GPIO==
{| class="wikitable"
|-
! GPIO Bank !! Address
|-
| GPIO 0 || 494
|-
| GPIO 1 || 471
|-
| GPIO 2 || 445
|-
| GPIO 3 || 429
|-
| GPIO 4 || 418
|-
| GPIO 5 || 398
|-
| GPIO 6 || 380
|}

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

alsactl store
</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_2X8/640x480 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/640x480 field:none]"
</pre>

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

==Known problems==

===WiFi module does not support random MAC===
By default, Network Manager will use random MAC for better security, somehow the module used on this board does not support it. You should disable it by edit file <code>/etc/NetworkManager/NetworkManager.conf</code>, add add lines below:
<pre>
[device]
wifi.scan-rand-mac-address=no
</pre>

===Set MAC address of ethernet card===
There is no EEPROM or SPI Flash to save MAC address for ethernet card. So you can set MAC address by yourself. e.g. Using Network Manager:
<pre>
sudo nmtui
</pre>

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

===No Graphic Accelerations on Debian rootfs===
2D/3D Graphic Accelerations are only supported in Renesas's customized Yocto, and only Wayland is supported.

===No Bayer Color Encoding Support===
Some cameras (like Sony IMX219) can only output RAW bayer video data, which is not supported by hardware encoders on the board. Even through you can convert color space with GStreamer element like bayer2rgb, it will cost lots of CPU resources and RAM bandwidth.
==Test==
===Enable Speaker Output===
<pre>
echo 393 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio393/direction
echo 1 > /sys/class/gpio/gpio393/value
gst-launch-1.0 audiotestsrc ! audioconvert ! audioresample ! autoaudiosink
</pre>
===Use Mic===
<pre>
arecord -Dhw:0,0 -f S16_LE -t wav -r44100 -c 2 record.wav
Note: not support sample rate 48000
</pre>
===RS485 Port===
<pre>
TTY： ttySC2
Note：
1. disable flow control
</pre>
===Enable Developer options in Android===
<pre>
Steps:
1. Find item "Buile number" (Path: Settings -> About tablet -> Build number)
2. click it 10 times
</pre>
===How to adb connect device through network===
<pre>
Debug console steps:
1. su
2. setprop service.adb.tcp.port 5555
3. stop adbd
4. start adbd
ADB connect command:
1. adb connect <Device IP>
</pre>

passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_2X8/640x480 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/640x480 field:none]"
</pre>

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

==Known problems==

===WiFi module does not support random MAC===
By default, Network Manager will use random MAC for better security, somehow the module used on this board does not support it. You should disable it by edit file <code>/etc/NetworkManager/NetworkManager.conf</code>, add add lines below:
<pre>
[device]
wifi.scan-rand-mac-address=no
</pre>

===Set MAC address of ethernet card===
There is no EEPROM or SPI Flash to save MAC address for ethernet card. So you can set MAC address by yourself. e.g. Using Network Manager:
<pre>
sudo nmtui
</pre>

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink

</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

==Using GPIO==
{| class="wikitable"
|-
! GPIO Bank !! Address
|-
| GPIO 0 || 494
|-
| GPIO 1 || 471
|-
| GPIO 2 || 445
|-
| GPIO 3 || 429
|-
| GPIO 4 || 418
|-
| GPIO 5 || 398
|-
| GPIO 6 || 380
|}

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

alsactl store
</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_2X8/640x480 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/640x480 field:none]"
</pre>

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

==Known problems==

===WiFi module does not support random MAC===
By default, Network Manager will use random MAC for better security, somehow the module used on this board does not support it. You should disable it by edit file <code>/etc/NetworkManager/NetworkManager.conf</code>, add add lines below:
<pre>
[device]
wifi.scan-rand-mac-address=no
</pre>

===Set MAC address of ethernet card===
There is no EEPROM or SPI Flash to save MAC address for ethernet card. So you can set MAC address by yourself. e.g. Using Network Manager:
<pre>
sudo nmtui
</pre>

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

===No Graphic Accelerations on Debian rootfs===
2D/3D Graphic Accelerations are only supported in Renesas's customized Yocto, and only Wayland is supported.

===No Bayer Color Encoding Support===
Some cameras (like Sony IMX219) can only output RAW bayer video data, which is not supported by hardware encoders on the board. Even through you can convert color space with GStreamer element like bayer2rgb, it will cost lots of CPU resources and RAM bandwidth.
==Test==
===Enable Speaker Output===
<pre>
echo 393 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio393/direction
echo 1 > /sys/class/gpio/gpio393/value
gst-launch-1.0 audiotestsrc ! audioconvert ! audioresample ! autoaudiosink
</pre>
===Use Mic===
<pre>
arecord -Dhw:0,0 -f S16_LE -t wav -r44100 -c 2 record.wav
Note: not support sample rate 48000
</pre>
===RS485 Port===
<pre>
TTY： ttySC2
Note：
1. disable flow control
</pre>
===Enable Developer options in Android===
<pre>
Steps:
1. Find item "Buile number" (Path: Settings -> About tablet -> Build number)
2. click it 10 times
</pre>
===How to adb connect device through network===
<pre>
Debug console steps:
1. su root
2. setprop service.adb.tcp.port 5555
3. stop adbd
4. start adbd
ADB connect command:
1. adb connect <Device IP>

</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

==Using GPIO==
{| class="wikitable"
|-
! GPIO Bank !! Address
|-
| GPIO 0 || 494
|-
| GPIO 1 || 471
|-
| GPIO 2 || 445
|-
| GPIO 3 || 429
|-
| GPIO 4 || 418
|-
| GPIO 5 || 398
|-
| GPIO 6 || 380
|}

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

alsactl store
</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_2X8/640x480 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/640x480 field:none]"
</pre>

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

==Known problems==

===WiFi module does not support random MAC===
By default, Network Manager will use random MAC for better security, somehow the module used on this board does not support it. You should disable it by edit file <code>/etc/NetworkManager/NetworkManager.conf</code>, add add lines below:
<pre>
[device]
wifi.scan-rand-mac-address=no
</pre>

===Set MAC address of ethernet card===
There is no EEPROM or SPI Flash to save MAC address for ethernet card. So you can set MAC address by yourself. e.g. Using Network Manager:
<pre>
sudo nmtui
</pre>

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

===No Graphic Accelerations on Debian rootfs===
2D/3D Graphic Accelerations are only supported in Renesas's customized Yocto, and only Wayland is supported.

===No Bayer Color Encoding Support===
Some cameras (like Sony IMX219) can only output RAW bayer video data, which is not supported by hardware encoders on the board. Even through you can convert color space with GStreamer element like bayer2rgb, it will cost lots of CPU resources and RAM bandwidth.
==Test==
===Enable Speaker Output===
<pre>
echo 393 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio393/direction
echo 1 > /sys/class/gpio/gpio393/value
gst-launch-1.0 audiotestsrc ! audioconvert ! audioresample ! autoaudiosink
</pre>
===Use Mic===
<pre>
arecord -Dhw:0,0 -f S16_LE -t wav -r44100 -c 2 record.wav
Note: not support sample rate 48000
</pre>
===RS485 Port===
<pre>
TTY： ttySC2
Note：
1. disable flow control
</pre>
===Enable Developer options in Android===
<pre>
Steps:
1. Find item "Buile number" (Path: Settings -> About tablet -> Build number)
2. click it 10 times
</pre>

cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

==Using GPIO==
{| class="wikitable"
|-
! GPIO Bank !! Address
|-
| GPIO 0 || 494
|-
| GPIO 1 || 471
|-
| GPIO 2 || 445
|-
| GPIO 3 || 429
|-
| GPIO 4 || 418
|-
| GPIO 5 || 398
|-
| GPIO 6 || 380
|}

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

alsactl store
</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_2X8/640x480 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/640x480 field:none]"
</pre>

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

==Known problems==

===WiFi module does not support random MAC===
By default, Network Manager will use random MAC for better security, somehow the module used on this board does not support it. You should disable it by edit file <code>/etc/NetworkManager/NetworkManager.conf</code>, add add lines below:
<pre>
[device]
wifi.scan-rand-mac-address=no
</pre>

===Set MAC address of ethernet card===
There is no EEPROM or SPI Flash to save MAC address for ethernet card. So you can set MAC address by yourself. e.g. Using Network Manager:
<pre>
sudo nmtui
</pre>

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

===No Graphic Accelerations on Debian rootfs===
2D/3D Graphic Accelerations are only supported in Renesas's customized Yocto, and only Wayland is supported.

===No Bayer Color Encoding Support===
Some cameras (like Sony IMX219) can only output RAW bayer video data, which is not supported by hardware encoders on the board. Even through you can convert color space with GStreamer element like bayer2rgb, it will cost lots of CPU resources and RAM bandwidth.
==Test==
===Enable Speaker Output===
<pre>
echo 393 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio393/direction
echo 1 > /sys/class/gpio/gpio393/value
gst-launch-1.0 audiotestsrc ! audioconvert ! audioresample ! autoaudiosink
</pre>
===Use Mic===
<pre>
arecord -Dhw:0,0 -f S16_LE -t wav -r44100 -c 2 record.wav
Note: not support sample rate 48000
</pre>
===RS485 Port===
<pre>
TTY： ttySC2
Note：
1. disable flow control

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

===WiFi module does not support random MAC===
By default, Network Manager will use random MAC for better security, somehow the module used on this board does not support it. You should disable it by edit file <code>/etc/NetworkManager/NetworkManager.conf</code>, add add lines below:
<pre>
[device]
wifi.scan-rand-mac-address=no
</pre>

===Set MAC address of ethernet card===
There is no EEPROM or SPI Flash to save MAC address for ethernet card. So you can set MAC address by yourself. e.g. Using Network Manager:
<pre>
sudo nmtui
</pre>

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

===No Graphic Accelerations on Debian rootfs===
2D/3D Graphic Accelerations are only supported in Renesas's customized Yocto, and only Wayland is supported.

===No Bayer Color Encoding Support===
Some cameras (like Sony IMX219) can only output RAW bayer video data, which is not supported by hardware encoders on the board. Even through you can convert color space with GStreamer element like bayer2rgb, it will cost lots of CPU resources and RAM bandwidth.

</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

==Using GPIO==
{| class="wikitable"
|-
! GPIO Bank !! Address
|-
| GPIO 0 || 494
|-
| GPIO 1 || 471
|-
| GPIO 2 || 445
|-
| GPIO 3 || 429
|-
| GPIO 4 || 418
|-
| GPIO 5 || 398
|-
| GPIO 6 || 380
|}

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

alsactl store
</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_2X8/640x480 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/640x480 field:none]"
</pre>

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

==Using GPIO==
{| class="wikitable"
|-
! GPIO Bank !! Address
|-
| GPIO 0 || 494
|-
| GPIO 1 || 471
|-
| GPIO 2 || 445
|-
| GPIO 3 || 429
|-
| GPIO 4 || 418
|-
| GPIO 5 || 398
|-
| GPIO 6 || 380
|}

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

alsactl store
</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_2X8/640x480 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/640x480 field:none]"
</pre>

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

==Known problems==

===WiFi module does not support random MAC===
By default, Network Manager will use random MAC for better security, somehow the module used on this board does not support it. You should disable it by edit file <code>/etc/NetworkManager/NetworkManager.conf</code>, add add lines below:
<pre>
[device]
wifi.scan-rand-mac-address=no
</pre>

===Set MAC address of ethernet card===
There is no EEPROM or SPI Flash to save MAC address for ethernet card. So you can set MAC address by yourself. e.g. Using Network Manager:
<pre>
sudo nmtui
</pre>

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

===No Graphic Accelerations on Debian rootfs===
2D/3D Graphic Accelerations are only supported in Renesas's customized Yocto, and only Wayland is supported.

===No Bayer Color Encoding Support===
Some cameras (like Sony IMX219) can only output RAW bayer video data, which is not supported by hardware encoders on the board. Even through you can convert color space with GStreamer element like bayer2rgb, it will cost lots of CPU resources and RAM bandwidth.
==Test==
===Enable Speaker Output===
<pre>
echo 393 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio393/direction
echo 1 > /sys/class/gpio/gpio393/value
gst-launch-1.0 audiotestsrc ! audioconvert ! audioresample ! autoaudiosink
</pre>
===Use Mic===
<pre>
arecord -Dhw:0,0 -f S16_LE -t wav -r44100 -c 2 record.wav
Note: not support sample rate 48000
</pre>
===RS485 Port===
<pre>
TTY： ttySC2
Note：
1. disable flow control
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

==Using GPIO==
{| class="wikitable"
|-
! GPIO Bank !! Address
|-
| GPIO 0 || 494
|-
| GPIO 1 || 471
|-
| GPIO 2 || 445
|-
| GPIO 3 || 429
|-
| GPIO 4 || 418
|-
| GPIO 5 || 398
|-
| GPIO 6 || 380
|}

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

alsactl store
</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_2X8/640x480 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/640x480 field:none]"
</pre>

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

==Known problems==

===WiFi module does not support random MAC===
By default, Network Manager will use random MAC for better security, somehow the module used on this board does not support it. You should disable it by edit file <code>/etc/NetworkManager/NetworkManager.conf</code>, add add lines below:
<pre>
[device]
wifi.scan-rand-mac-address=no
</pre>

===Set MAC address of ethernet card===
There is no EEPROM or SPI Flash to save MAC address for ethernet card. So you can set MAC address by yourself. e.g. Using Network Manager:
<pre>
sudo nmtui
</pre>

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

===No Graphic Accelerations on Debian rootfs===
2D/3D Graphic Accelerations are only supported in Renesas's customized Yocto, and only Wayland is supported.

===No Bayer Color Encoding Support===
Some cameras (like Sony IMX219) can only output RAW bayer video data, which is not supported by hardware encoders on the board. Even through you can convert color space with GStreamer element like bayer2rgb, it will cost lots of CPU resources and RAM bandwidth.
==Test==
===Enable Speaker Output===
<pre>
echo 393 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio393/direction
echo 1 > /sys/class/gpio/gpio393/value
gst-launch-1.0 audiotestsrc ! audioconvert ! audioresample ! autoaudiosink
</pre>
===Use Mic===
<pre>
arecord -Dhw:0,0 -f S16_LE -t wav -r44100 -c 2 record.wav
Note: not support sample rate 48000
</pre>
===RS485 Port===
<pre>
TTY： ttySC2
Note：
1. disable flow control
</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

===No Graphic Accelerations on Debian rootfs===
2D/3D Graphic Accelerations are only supported in Renesas's customized Yocto, and only Wayland is supported.

===No Bayer Color Encoding Support===
Some cameras (like Sony IMX219) can only output RAW bayer video data, which is not supported by hardware encoders on the board. Even through you can convert color space with GStreamer element like bayer2rgb, it will cost lots of CPU resources and RAM bandwidth.

</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

==Using GPIO==
{| class="wikitable"
|-
! GPIO Bank !! Address
|-
| GPIO 0 || 494
|-
| GPIO 1 || 471
|-
| GPIO 2 || 445
|-
| GPIO 3 || 429
|-
| GPIO 4 || 418
|-
| GPIO 5 || 398
|-
| GPIO 6 || 380
|}

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

alsactl store
</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_2X8/640x480 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/640x480 field:none]"
</pre>

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

==Known problems==

===WiFi module does not support random MAC===
By default, Network Manager will use random MAC for better security, somehow the module used on this board does not support it. You should disable it by edit file <code>/etc/NetworkManager/NetworkManager.conf</code>, add add lines below:
<pre>
[device]
wifi.scan-rand-mac-address=no
</pre>

===Set MAC address of ethernet card===
There is no EEPROM or SPI Flash to save MAC address for ethernet card. So you can set MAC address by yourself. e.g. Using Network Manager:
<pre>
sudo nmtui
</pre>

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

===No Graphic Accelerations on Debian rootfs===
2D/3D Graphic Accelerations are only supported in Renesas's customized Yocto, and only Wayland is supported.

===No Bayer Color Encoding Support===
Some cameras (like Sony IMX219) can only output RAW bayer video data, which is not supported by hardware encoders on the board. Even through you can convert color space with GStreamer element like bayer2rgb, it will cost lots of CPU resources and RAM bandwidth.
==Test==
===Enable Speaker Output===
<pre>
echo 393 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio393/direction
echo 1 > /sys/class/gpio/gpio393/value
gst-launch-1.0 audiotestsrc ! audioconvert ! audioresample ! autoaudiosink
</pre>
===Use Mic===
<pre>
arecord -Dhw:0,0 -f S16_LE -t wav -r44100 -c 2 record.wav
Note: not support sample rate 48000
</pre>
===RS485 Port===
<pre>
TTY： ttySC2
Note：
1. disable flow control
</pre>

</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

==Using GPIO==
{| class="wikitable"
|-
! GPIO Bank !! Address
|-
| GPIO 0 || 494
|-
| GPIO 1 || 471
|-
| GPIO 2 || 445
|-
| GPIO 3 || 429
|-
| GPIO 4 || 418
|-
| GPIO 5 || 398
|-
| GPIO 6 || 380
|}

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

alsactl store
</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_2X8/640x480 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/640x480 field:none]"
</pre>

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

==Known problems==

===WiFi module does not support random MAC===
By default, Network Manager will use random MAC for better security, somehow the module used on this board does not support it. You should disable it by edit file <code>/etc/NetworkManager/NetworkManager.conf</code>, add add lines below:
<pre>
[device]
wifi.scan-rand-mac-address=no
</pre>

===Set MAC address of ethernet card===
There is no EEPROM or SPI Flash to save MAC address for ethernet card. So you can set MAC address by yourself. e.g. Using Network Manager:
<pre>
sudo nmtui
</pre>

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

===No Graphic Accelerations on Debian rootfs===
2D/3D Graphic Accelerations are only supported in Renesas's customized Yocto, and only Wayland is supported.

===No Bayer Color Encoding Support===
Some cameras (like Sony IMX219) can only output RAW bayer video data, which is not supported by hardware encoders on the board. Even through you can convert color space with GStreamer element like bayer2rgb, it will cost lots of CPU resources and RAM bandwidth.
==Test==
===Enable Speaker Output===
<pre>
echo 393 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio393/direction
echo 1 > /sys/class/gpio/gpio393/value
gst-launch-1.0 audiotestsrc ! audioconvert ! audioresample ! autoaudiosink
</pre>
===Use Mic===
<pre>
arecord -Dhw:0,0 -f S16_LE -t wav -r44100 -c 2 record.wav
Note: not support sample rate 48000
</pre>
===RS485 Port===
<pre>
TTY： ttySC2
Note：
1. disable flow control
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt

cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

==Known problems==

===WiFi module does not support random MAC===
By default, Network Manager will use random MAC for better security, somehow the module used on this board does not support it. You should disable it by edit file <code>/etc/NetworkManager/NetworkManager.conf</code>, add add lines below:
<pre>
[device]
wifi.scan-rand-mac-address=no
</pre>

===Set MAC address of ethernet card===
There is no EEPROM or SPI Flash to save MAC address for ethernet card. So you can set MAC address by yourself. e.g. Using Network Manager:
<pre>
sudo nmtui
</pre>

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

===No Graphic Accelerations on Debian rootfs===
2D/3D Graphic Accelerations are only supported in Renesas's customized Yocto, and only Wayland is supported.

===No Bayer Color Encoding Support===
Some cameras (like Sony IMX219) can only output RAW bayer video data, which is not supported by hardware encoders on the board. Even through you can convert color space with GStreamer element like bayer2rgb, it will cost lots of CPU resources and RAM bandwidth.

</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

==Using GPIO==
{| class="wikitable"
|-
! GPIO Bank !! Address
|-
| GPIO 0 || 494
|-
| GPIO 1 || 471
|-
| GPIO 2 || 445
|-
| GPIO 3 || 429
|-
| GPIO 4 || 418
|-
| GPIO 5 || 398
|-
| GPIO 6 || 380
|}

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

alsactl store
</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_2X8/640x480 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/640x480 field:none]"
</pre>

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

==Known problems==

</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

==Using GPIO==
{| class="wikitable"
|-
! GPIO Bank !! Address
|-
| GPIO 0 || 494
|-
| GPIO 1 || 471
|-
| GPIO 2 || 445
|-
| GPIO 3 || 429
|-
| GPIO 4 || 418
|-
| GPIO 5 || 398
|-
| GPIO 6 || 380
|}

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

alsactl store
</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_2X8/640x480 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/640x480 field:none]"
</pre>

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

==Known problems==

===WiFi module does not support random MAC===
By default, Network Manager will use random MAC for better security, somehow the module used on this board does not support it. You should disable it by edit file <code>/etc/NetworkManager/NetworkManager.conf</code>, add add lines below:
<pre>
[device]
wifi.scan-rand-mac-address=no
</pre>

===Set MAC address of ethernet card===
There is no EEPROM or SPI Flash to save MAC address for ethernet card. So you can set MAC address by yourself. e.g. Using Network Manager:
<pre>
sudo nmtui
</pre>

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

===No Graphic Accelerations on Debian rootfs===
2D/3D Graphic Accelerations are only supported in Renesas's customized Yocto, and only Wayland is supported.

===No Bayer Color Encoding Support===
Some cameras (like Sony IMX219) can only output RAW bayer video data, which is not supported by hardware encoders on the board. Even through you can convert color space with GStreamer element like bayer2rgb, it will cost lots of CPU resources and RAM bandwidth.
==Test==
===Enable Speaker Output===
<pre>
echo 393 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio393/direction
echo 1 > /sys/class/gpio/gpio393/value
gst-launch-1.0 audiotestsrc ! audioconvert ! audioresample ! autoaudiosink
</pre>
===Use Mic===
<pre>
arecord -Dhw:0,0 -f S16_LE -t wav -r44100 -c 2 record.wav
Note: not support sample rate 48000
</pre>
===RS485 Port===
<pre>
TTY： ttySC2
Note：
1. disable flow control
</pre>

===Build Linux Kernel===
<pre>
cd linux-cip
./build-g2e.sh
</pre>

===Create Linux root filesystem===
Prepare a SD card with capacity of 16GB or more.
Use partition tool like fdisk, create 2 partitions on SD card: first partition should be FAT16/32, with size at least 64MiB, secord partition should be ext4, size should be at least 8GiB.
Copy files below into first partition (replace /dev/sdb1 to the first partition of your real SD card device path):
<pre>
sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2e/Image /mnt
cp -v linux-cip/deploy/g2e/r8a774c0-rzg2e-novotech.dtb /mnt
cp -v linux-cip/deploy/g2e/modules.tar.gz /mnt
umount /dev/sdb1
exit
</pre>

Then create Debian 10 (Buster) rootfs:
<pre>
sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager buster "${ROOTFS}" http://deb.debian.org/debian

chroot "${ROOTFS}"
passwd root
#Input your root password

exit

tar -xf ../linux-cip/deploy/g2e/modules.tar.gz
tar -czpf ../debian-buster-rootfs.tar.gz .

exit
</pre>

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).
<pre>
sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-buster-rootfs.tar.gz -C /mnt

# Copy rootfs to SD card so that you can install it to eMMC (Optional):
cp -v debian-buster-rootfs.tar.gz /mnt

umount /dev/sdb2
exit
</pre>

===Boot kernel & rootfs from SD card===
At u-boot auto booting count down, press enter to break into u-boot command-line. Use commands below to boot from SD card:
<pre>
setenv bootargs 'root=/dev/mmcblk0p2 rootwait rw'
fatload mmc 0:1 0x48080000 Image; fatload mmc 0:1 0x48000000 r8a774c0-rzg2e-novotech.dtb; booti 0x48080000 - 0x48000000
</pre>
The device path of SD card is /dev/mmcblk0, and the path of eMMC is /dev/mmcblk2. Kernel and rootfs can be written into eMMC with the same partition structure as SD card.

<code>GPIO Number = GPIO Bank Address + Pin Number</code>. e.g, GPIO number of GPIO 2-2 is 445+2=447.

You use user level interfaces in <code>/sys/class/gpio</code> to operate GPIOs. Just like other ARM platforms.

You can check GPIO stats by reading <code>/sys/kernel/debug/gpio</code>:
<pre>
sudo cat /sys/kernel/debug/gpio
</pre>

==Using Audio SoC==
At first running, ALSA should be configured with the commands below:
<pre>
amixer cset name="HP Playback Switch" on
amixer cset name="HPO MIDAC1 Switch" on
amixer cset name="Stereo DAC MIXL DAC L1 Switch" on
amixer cset name="Stereo DAC MIXR DAC R1 Switch" on
amixer cset name="DAC MIXL INF1 Switch" on
amixer cset name="DAC MIXR INF1 Switch" on
amixer cset name="DAC MIXL Stereo ADC Switch" off
amixer cset name="DAC MIXR Stereo ADC Switch" off
amixer cset name="ADC Capture Switch" on
amixer cset name="Stereo1 ADC MIXL ADC1 Switch" on
amixer cset name="Stereo1 ADC MIXR ADC1 Switch" on

amixer cset name="RECMIXL INL1 Switch" on
amixer cset name="RECMIXR INR1 Switch" on
amixer cset name="RECMIXL BST1 Switch" on
amixer cset name="RECMIXR BST1 Switch" on

alsactl store
</pre>

If you are using non-standard Linux distributions (like customized Yocto or buildroot), you should write the mixer configurations in startup script.

==Using Camera==
Camera Module: Sony IMX219

Use commands below to initialize media controller:

FHD(1920x1080) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_1X8/1920x1080 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/1920x1080 field:none]"
</pre>

VGA(640x480) mode:
<pre>
media-ctl -d /dev/media0 -r
media-ctl -d /dev/media0 -l "'rcar_csi2 feaa0000.csi2':1 -> 'VIN4 output':0 [1]"
media-ctl -d /dev/media0 -V "'rcar_csi2 feaa0000.csi2':1 [fmt:SRGGB8_2X8/640x480 field:none]"
media-ctl -d /dev/media0 -V "'imx219 0-0010':0 [fmt:SRGGB8_1X8/640x480 field:none]"
</pre>

Camera device will be /dev/video0 on Debian rootfs, and /dev/video8 on Yocto rootfs.

Camera subdev device will be /dev/v4l-subdev1 on Debian rootfs, and /dev/v4l-subdev18 on Yocto rootfs.

You can use <code>mediactl -d /dev/media0 -p</code> to check device status.

You can use commands below to configure camera parameters (on Debian rootfs):
<pre>
#Set exposure
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl exposure=1600

#Set analog gain
v4l2-ctl -d /dev/v4l-subdev1 --set-ctrl analogue_gain=232

#Check camera controllers
v4l2-ctl -d /dev/v4l-subdev1 --list-ctrls
</pre>

Use GStreamer to get a photo (on Debian rootfs):
<pre>
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! video/x-bayer,format=rggb,width=1920,height=1080,framerate=30/1 ! bayer2rgb ! videoflip video-direction=4 ! videoflip video-direction=5 ! jpegenc ! filesink location=camsnap.jpg
</pre>

Use GStreamer to show video from camera (on Yocto rootfs, need Wayland support):
<pre>
gst-launch-1.0 v4l2src device=/dev/video8 io-mode=dmabuf ! video/x-bayer,format=rggb,width=640,height=480,framerate=30/1 ! bayersink
</pre>

==Known problems==

===WiFi module does not support random MAC===
By default, Network Manager will use random MAC for better security, somehow the module used on this board does not support it. You should disable it by edit file <code>/etc/NetworkManager/NetworkManager.conf</code>, add add lines below:
<pre>
[device]
wifi.scan-rand-mac-address=no
</pre>

===Set MAC address of ethernet card===
There is no EEPROM or SPI Flash to save MAC address for ethernet card. So you can set MAC address by yourself. e.g. Using Network Manager:
<pre>
sudo nmtui
</pre>

Edit your ethernet connection, unfold ETHERNET option, set "Cloned MAC address" to the address you want. Then exit the tool to save your settings.

Or you can set MAC address in u-boot, press Enter key when u-boot is waiting for interrupting, then set MAC address with commands below:
<pre>
setenv ethaddr "AC:F3:5F:1E:87:53"
saveenv
</pre>

You can replace the address with the one you want.

===No Graphic Accelerations on Debian rootfs===
2D/3D Graphic Accelerations are only supported in Renesas's customized Yocto, and only Wayland is supported.

===No Bayer Color Encoding Support===
Some cameras (like Sony IMX219) can only output RAW bayer video data, which is not supported by hardware encoders on the board. Even through you can convert color space with GStreamer element like bayer2rgb, it will cost lots of CPU resources and RAM bandwidth.
==Test==
===Enable Speaker Output===
<pre>
echo 393 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio393/direction
echo 1 > /sys/class/gpio/gpio393/value
gst-launch-1.0 audiotestsrc ! audioconvert ! audioresample ! autoaudiosink
</pre>
===Use Mic===
<pre>
arecord -Dhw:0,0 -f S16_LE -t wav -r44100 -c 2 record.wav
Note: not support sample rate 48000
</pre>
===RS485 Port===
<pre>
TTY： ttySC2
Note：
1. disable flow control
</pre>
