Boot Flash Burner from serial port

Set serial port of PC to 115200bps, 8N1. Set boot mode of board to download mode. Connect Debug port of board to the serial port of PC. Power on the board, then something like "please send !" will be printed on terminal.

Upload file rzg2-flash-writer/AArch64_output/Flash_Writer_SCIF_RZG2L_SMARC_DDR4_2GB.mot (or rzg2-flash-writer/AArch64_output/Flash_Writer_SCIF_RZV2L_SMARC_DDR4_4GB.mot for V2L SoC) with ASCII mode. After uploading, prompt ">" will appear in terminal.

eMMC Boot Settings

Please note that for eMMC booting, the following EXT_CSD registers need to be modified:

EXT_CSD[B1] = 0x02
EXT_CSD[B3] = 0x08

Use EM_SECSD command to modify EXT CSD registers:

>EM_SECSD
  Please Input EXT_CSD Index(H'00 - H'1FF) :b1
  EXT_CSD[B1] = 0x00
  Please Input Value(H'00 - H'FF) :2
  EXT_CSD[B1] = 0x02

>EM_SECSD
  Please Input EXT_CSD Index(H'00 - H'1FF) :b3
  EXT_CSD[B1] = 0x00
  Please Input Value(H'00 - H'FF) :8
  EXT_CSD[B1] = 0x08

Check Bootloader

Power off the board. Set boot mode to eMMC boot. Then power on. It should be able to boot into u-boot:

Build Linux Kernel

cd linux-cip
./build-g2l.sh

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):

For G2L with 1GB RAM:

sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2l/Image /mnt
cp -v linux-cip/deploy/g2l/r9a07g044l2-rzg2l-novotech.dtb /mnt/r9a07g044l2-rzg2l-novotech.dtb
cp -v linux-cip/deploy/g2l/modules.tar.gz /mnt
umount /dev/sdb1
exit

For G2L with 2GB RAM:

sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2l/Image /mnt
cp -v linux-cip/deploy/g2l/r9a07g044l2-rzg2l-novotech2.dtb /mnt/r9a07g044l2-rzg2l-novotech.dtb
cp -v linux-cip/deploy/g2l/modules.tar.gz /mnt
umount /dev/sdb1
exit

For G2L with 4GB RAM:

sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2l/Image /mnt
cp -v linux-cip/deploy/g2l/r9a07g044l2-rzg2l-novotech4.dtb /mnt/r9a07g044l2-rzg2l-novotech.dtb
cp -v linux-cip/deploy/g2l/modules.tar.gz /mnt
umount /dev/sdb1
exit

For V2L with 2GB RAM:

sudo -s
mount /dev/sdb1 /mnt
cp -v linux-cip/deploy/g2l/Image /mnt
cp -v linux-cip/deploy/g2l/r9a07g054l2-rzv2l-novotech2.dtb /mnt/r9a07g054l2-rzv2l-novotech.dtb
cp -v linux-cip/deploy/g2l/modules.tar.gz /mnt
umount /dev/sdb1
exit

Then create Debian 12 (Bookworm) rootfs:

sudo -s
apt-get install qemu-user-static debootstrap schroot

mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager bookworm "${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-bookworm-rootfs.tar.gz .

exit

Mount and extract rootfs to the second partition of your SD card (replace /dev/sdb2 to your one).

sudo -s
mount /dev/sdb2 /mnt
tar -xpzf debian-bookworm-rootfs.tar.gz -C /mnt

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

umount /dev/sdb2
exit

Using pre-built system image

Debian 12 (Bookworm) pre-built SD card image (need at least 16GB capacity): http://dl.ariaboard.com/renesas_g2l/images/rzg2l-debian-bookworm-sd-20241010.img.gz

on PC:Pre-built system image can be used with both eMMC and SD card. Use commands below on PC to restore disk image to SD card (assume the SD card device is /dev/sdb and image file is emmc.img.gz):

#on a Linux PC:
zcat emmc.img.gz | sudo dd of=/dev/sdb bs=1M status=progress
sync

#on the Linux PC: Copy image to SD card so that you can restore it to eMMC (Optional):
sudo -s
partprobe
mount /dev/sdb2 /mnt
cp -v emmc.img.gz /mnt
umount /mnt

Boot kernel & rootfs from SD card

At u-boot auto booting count down, press Escape twice to break into u-boot command-line. Use commands below to boot from SD card:

run sdboot

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.

If you copied system image to SD card, you can restore it to eMMC with commands below:

zcat emmc.img.gz | sudo dd of=/dev/mmcblk0 bs=1M status=progress
sync

Enable Audio AMP

Set GPIO 43-0 to High:

Kernel 4.19:

echo 464 >/sys/class/gpio/export
echo out >/sys/class/gpio/gpio464/direction
echo 1 >/sys/class/gpio/gpio464/value

Kernel 5.10:

echo 464 >/sys/class/gpio/export
echo out >/sys/class/gpio/P43_0/direction
echo 1 >/sys/class/gpio/P43_0/value

Power Control of Wireless

Set GPIO 4-1 to Low:

Kernel 4.19:

echo 153 >/sys/class/gpio/export
echo out >/sys/class/gpio/gpio153/direction
echo 0 >/sys/class/gpio/gpio153/value

Kernel 5.10:

echo 153 >/sys/class/gpio/export
echo out >/sys/class/gpio/P4_1/direction
echo 0 >/sys/class/gpio/P4_1/value
