hi Erico,
not sure about boot.ini/UART thingy - i think C2 gets stuck on u-boot as i
never see kernel heartbeat blink the blue-LED and i dont have
UART/Serial/USB cable yet (placed the order for one). SD card is fine
(Sandisk Ultra, fresh, have tried with Armbian and Hardkernel's Ubuntu
images) and is new.
If i had the UART, i'd probably know where it gets stuck. If you do have C2
- can you try building / burning vanilla config (i made 0 modifications)
and see if it would boot on yours ? i doubt it.

tx !
