U-boot 

(1) Power on the board and stop in u-boot command prompt 

(2) Run the following command to => mmc rescan 

(3) Use the following command to set bootargs to use USB rootfs 

=> setenv bootargs root=/dev/sda2 rw rootwait rootfstype=ext4 earlycon=uart8250,mmio,0x21c0500 console=ttyS0,115200 loglevel=8 nohz=off 

 (4) Use the following commands to load Linux kernel and device tree blob from USB 

=> usb start

=> fatload usb 0:1 0x81000000 Image (5) Use the following command to boot the Linux kernel 

=> booti 0x81000000 - 0x8f000000

AMD64 Ubuntu rootfs howto

 1. Preparing the packages in host

sudo apt-get install  debootstrap qemu-user-static

2. Download the packages for ubuntu rootfs
debootstrap_dir=ubuntu-arm64-jammy

sudo debootstrap --arch arm64 --foreign jammy "$debootstrap_dir" http://ports.ubuntu.com/ubuntu-ports

3. Install the packages/ second-stage
sudo mkdir -p "${debootstrap_dir}/usr/bin"
sudo cp "$(which qemu-aarch64-static)" "${debootstrap_dir}/usr/bin"
sudo chroot "$debootstrap_dir" /debootstrap/debootstrap --second-stage

4. Remove the passwd of root
sudo chroot "$debootstrap_dir"
Edit /etc/passwd and /etc/shadow, remove the "*" in between ":" and ":" in root:....

5. Enable UART console
sudo chroot ${debootstrap_dir}
ln  -sf /lib/systemd/system/serial-getty\@.service /lib/systemd/system/getty.target.wants/

6. /etc/network/interfaces
sudo apt install ifupdown
vi /etc/network/interface
-----
source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

# The intranet network interface
auto eth1
iface eth1 inet static
     address 10.19.132.49
     netmask 255.255.254.0

7. Add locale
sudo vi /etc/locale.gen
umakrk en_US.UTF-8 UTF-8 and zh_TW.UTF-8 UTF-8
sudo locale-gen
