Quoted from Wolfmarsh:I was wondering the same, but I bet you'd have to be logging the voltage on a scope or something when it fails to see the drop.
I know the SoC they used has a watchdog, but I am not 100% sure if it has brown-out detection or not.
Guessing the PSU is likely the case here not the Cpu board. Would make more sense for the cheap china psu to bite the dust before the medium priced china cpu bit the dust.
Sigh. I like how my question just gets glossed over. whats the point in asking for help if you wont take advice from real techs. Check the 5volt rail. Shotgunning parts is not gonna tell you anything.
check it at the psu unit itself and on the cpu. Should be a test point on the cpu saying 5voolt test. Likely a stand off stud or large solder pad.
Also are these psu adjustable? is there a 5 volt pot that can be adjusted? They look like server psu units.
dead smack in the middle of board is a rx tx led tell me if those are on when the game fails to boot.
