It is the full size Pixhawk before the 2.1.
I have had it for about two years with no problem, it started this last week, so I was hoping that this new firmware would hopefully sort it out.
The only thing I did differently was power the board up while the outboard motor was running at the time.
Could the vibration from the motor during the startup have anything to do with it?
Yes, I tried that boot procedure, still nothing.
It appears this board is 'shot', no idea why or what caused it.
