The (half) board voltage is connected on board to the ADC subsystem @
channel AIN-7. Just read that samples. (I wrote libpruio

*io_input* or *oszi*.)

Sure this is a hardware-problem and not caused by the software on your

firmware ever work properly with the original BBB-hardware?

Angstrom is far more complicated than Debian. Based on your experience
level, I would go with Debian.

I have done nothing to mess with the hardware or the EEPROM.
All I have done it loaded machinekit from a sd card.

I think this can only mean that a device isn't responding to the address
