Device is dead!

  • Hi all. I'm new and need some help. After much effort I managed to get the device to update firmware via the command prompt. I have moved on to try and make a little project with the OLED expansion. I plugged the OLED in and turned the power back on and the Onion 2+ now appears to be dead. I just swapped a new onion 2 into the expansion board and it seems to power on but the other is completely dead- no LED's no life at all. What have I done? Any suggestions?

    Basic debugging on these is to disconnect all peripherals, and connect a logic level serial port or USB converter to the console serial and see what if anything is printed during the boot attempt.

    Permanent damage, while possible, is much less likely than mixed up software state.
