- UART has unusual speed: 1500000
- boot from SD card is possible by shorting TP50265 to the ground and powering the board. After Armbian boots up, you can overwrite eMMC. You need to do this procedure only once or in case you totally brick your system.
- once you have Armbian booting from eMMC, you can boot SD card in more simple manner: stop booting from UART console and execute those commands:
setenv devnum 1
followed byrun mmc_boot
- you need to use
EXPERT="yes"
to build kernel or images.
