I think I did something dumb - Tried booting Armbian Bookworm for Rock64, now won't boot

uConsole
1

Today I flashed a new SD card with Armbian 23.5.1 Rock64 bookworm. I tried booting from it and got nothing, blank screen.

I swapped the SD card that came with my A06 back in and still no boot. I found this post: A04 won't boot after reflashing sd card but I don’t think it really applies.

I tried finding instructions on how to connect to the UART interface but I’m not seeing anything specific to uConsole.

Any ideas or guidance is greatly appreciated

Tried holding the power button for longer than normal and it booted with the original SD card. Weird.
