TinkerBoard not booting 6.18

[Foz]

I think I have a dodgy board, so ignore me now. It was old, and I was planning on buying an sbc with more gumption soon.
So that will have to be put to the top of the list.
Sorry to have wasted time.

No worries, if you are as well not able to run another Debian-based OS currently, then I agree .
