very wierd, no boot, sort of fixed - wdt - 02-10-2020
If this happens to you, something to try, costs little
This fairly serious, I just spent 2-3 hours to narrow it down
So, I thought I had broke it, the power button did nothing, removed q4os SD, still nothing
For some reason, I tried holding power 15 sec, nothing, thought try longer (and 20+ is right)
Then a short push and started right up, hmm, hmm
Put q4os back in, reboot, same senario (dead power button, hold 20+s, then works (q4os out))
Tried with nothing in SD slot, worked OK, tried with debian bullseye, worked OK,
tried with manjaro, worked OK (reboot worked, after shutdown restarts normally)
Checked 1st 16M, diff and cmp they vary quite a bit,
downloaded a stock mrfixit and updated, 1st 16 match (aside from mbr) (with emmc)
So q4os has some problem with uboot? or ibdloader?
I never did get q4os booted
why the 20 second push????
--edit-- SOLVED
turned out to be wrong card, identical (appearance) card hiding nearby
I wish there was a way to mark cards, that doesn't rub off or gum up SD slot
