Ok so now I have four rockpro64 boards available for testing. Only this one stubborn board refuses to boot after power loss. I must hold down the on/off button for 3 seconds, then short press then it will start.
The offending board is year plus old but has not been in service. Of the 4 two are brand new and the other is the same vintage (no problems with it).
So what could be the reasons that this one board (and only this board) not power up after power loss? It's telling that I can't just hit the on/off button once for it to boot. I must "shutown" the board first with a long press and start again with a short press.
Makes me think that some bootstrap circuit/firmware is hung on poswerloss power on vs power on via the button. At this point it's a bummer not a brick. I won't be able to use it headless/unattended if I can't get to start after power loss.
