Recovery boot
1. Make sure the BOOT mode is set to UART. 2. Connect to the debug UART with your computer and launch the serial terminal application
picocom -b 115200 /dev/ttyUSB0 --send-cmd "sz -vv -X" --receive-cmd "rz -vv -X"
3. Start the board. When "CCCC" characters appear on terminal window, do:
C-a C-s *** file: u-boot-spl.bin
4. Exit from picocom using C-a C-q, and relaunch picocom with
picocom -b 115200 /dev/ttyUSB0 --send-cmd "sz -vv -Y" --receive-cmd "rz -vv -Y"
5. When "CCCC" characters appear on terminal window, do:
C-a C-s *** file: u-boot.bin
6. Hitting any key to stop automatic boot, should present the U-Boot prompt.
