斷開連接，關閉電源，更改撥碼開關。

接上SD卡（SD卡需要提前做好分區以及格式），將Linux kernel、Devise tree、root filesystem復制到/media/user/rootfs/home/root/

輸入命令

$ sudo cp ~/rzg_vlp_v3.0.3/build/tmp/deploy/images/smarc-rzg2l/Image-smarc-rzg2l.bin /media/venon/rootfs/home/root/
$ sudo cp ~/rzg_vlp_v3.0.3/build/tmp/deploy/images/smarc-rzg2l/Image-r9a07g044l2-smarc.dtb /media/venon/rootfs/home/root/
$ sudo cp ~/rzg_vlp_v3.0.3/build/tmp/deploy/images/smarc-rzg2l/core-image-qt-smarc-rzg2l.tar.bz2 /media/venon/rootfs/home/root/

插入SD卡，啟動G2L EVK，啟動Linux后以root用戶身份登錄

在eMMC中創建分區

輸入如下命令

root@smarc-rzv2l:~# fdisk /dev/mmcblk0
Welcome to fdisk (util-linux 2.35.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Command (m for help): o
Created a new DOS disklabel with disk identifier 0xf3d53104.
Command (m for help): n
Partition type
p primary (0 primary, 0 extended, 4 free)
e extended (container for logical partitions)
Select (default p): (Push the enter key)
Partition number (1-4, default 1): (Push the enter key)
First sector (2048-124321791, default 2048): (Push the enter key)
Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-124321791, default 1243217

root@smarc-rzv2l:~#

格式化eMMC

輸入命令

root@smarc-rzv2l:~# mkfs.ext4 /dev/mmcblk0p1
root@smarc-rzv2l:~# mkfs.ext4 /dev/mmcblk0p2

格式化eMMC并寫入內核、設備樹和rootfs

root@smarc-rzg2l:~# mount /dev/mmcblk0p1 /mnt/
root@smarc-rzg2l:~# cp Image-smarc-rzg2l.bin /mnt/
root@smarc-rzg2l:~# cp Image-r9a07g044l2-smarc.dtb /mnt/
root@smarc-rzg2l:~# umount /dev/mmcblk0p1
root@smarc-rzg2l:~# mount /dev/mmcblk0p2 /mnt/root@smarc-rzg2l:~# tar xf /home/root/core-image-qt-smarc-rzg2l.tar.bz2 -C /mnt/
root@smarc-rzg2l:~# umount /dev/mmcblk0p2

按下復位按鍵SW10，或者輸入命令reboot重啟設備，配置U-boot環境變量。

=> setenv bootargs 'root=/dev/mmcblk0p2 rootwait'
=> setenv bootcmd 'mmc dev 1; ext4load mmc 0:1 0x48080000 Image-smarc-rzg2l.bin; ext4load mmc 0:1 0x48000000 Image-r9a07g044l2-smarc.dtb; booti 0x48080000 - 0x48000000'
=> saveenv
Saving Environment to MMC... Writing to MMC(0)... OK

按下復位按鍵或者輸入命令‘reset’。重啟設備。
