Reading theories re: the problem in earlier posts I decided to try an external power supply.
I plugged in a 12 volt 5A supply, and it has modified the behavior (without really solving the problem).
Prior to plugging in the supply, every time I ran ‘LimeUtil --update’ it would report the gateware mismatch, and seem to re-flash the board. Running the update several times in succession, each time it would report the mismatch.
With the external supply the update sometimes works. But even when it does, when I run my software I get a ‘ResetChip()’ fail. At which point the gateware mismatch is back.
How many folks are using V12?
