Testing update
I made a clean 08-31-2917 sd card image and bootsd it to see if that
worked as well and it worked running python and the ADC test.
I did the test both in cloud9 and ssh into as debian user.
I made none of the fixes from this thread to the image just booted and
tried the ADC test
So 08-31-2017 image works in flash as stated in my previous post and
from an sd card with a working 0831-2017 image in eMMC.
So I ask did you apply a fix to the 08-31-2017 image such as the udder rule
mentioned here.
