Are you grounding the pin before reading? Are you connecting to 3V3
before reading?
If you are reading a floating input (ie not connected) you will have
problems.
If you have a copy of the Device Summary, SPRS717G, you can find out
what the floating pin will read.

I'm trying simple scripts and find that P8_7 - 10 always return "1"
when set as inputs. Researching this I find that all sample code uses
P8_11, 12 or 14 for digital input. I understand that some pins might
be requisitioned for other functions in the Beagle, but I don't see
that these pins are. It took me HOURS to figure out why dirt simple
code would not run. But I'd like to understand why I can't make these
pins inputs (with Adafruit GPIO or Unix file commands) when the
documentation suggests they would work.
