sudo ./fastboot flash ram ./images/boot/u-boot-with-spl.bin
sudo ./fastboot reboot
# Wait a few seconds for the board to reboot.
sudo ./fastboot flash uboot ./images/boot/u-boot-with-spl.bin

Logging into the System

Insert the MicroSD card into LPi4A and reboot. Use a serial connection to log in; the author used minicom.

minicom -D /dev/ttyACM0 -c on

Default username: root Password needs to be set after boot.

Boot logs are in bootLog.txt in the same folder.

Expected Results

System boots normally and allows login via onboard serial port. If network is connected, SSH login should also work.

Actual Results
