Turns out what was in flash was dead, would not even boot.
I may have booted from flash on this board once when I first purchased the
board last fall.
So I have no idea what happened to flash or when.
So I downloaded the latest 08/31/2017 IOT image and converted it to a
flasher image and
flashed the eMMC with it.
It flashed fine and booted, which said at least the eMMC was not defective
I took a look at what was there using a cloud9 terminal as I have not run
connman yet
and tried python Adafruit_BBIO ADC and it worked.
I did not execute any of the commands to create a new group and change file
permissions.
It just worked out of the box.
Did you make any changes to the 08/31 image from this discussion that would
have fixed the issue?
Tomorrow I can try an sd card with a fresh image without the fixed
discussed earlier today and see what
happens with flash having a good image.
Here is what I did
