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 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):
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
Then create Debian 11 (Bullseye) rootfs:
sudo -s
apt-get install qemu-user-static debootstrap schroot
mkdir debian-rootfs
cd debian-rootfs
export ROOTFS="$(pwd)"
qemu-debootstrap --arch arm64 --variant buildd --include=ca-certificates,apt,wget,sudo,debootstrap,isc-dhcp-client,nano,network-manager bullseye "${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
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-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
Using pre-built system image
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
