Doesn't work on Linux 4.9.0 with aarch64

[russell]

From what i can see some of the expected values from /proc/cpuinfo when running with a aarch64 kernel are missing. This is causing the board detection to fail. But it seems that there is some device info is also listed in /proc/device-tree/model is there a possibility to add a fall back to that value for detection? The image I'm using is listed on this page https://wiki.debian.org/RaspberryPi3

I've tested this with the 0.10.0 and the v2 branch.

/root/plantower/venv/src/rpio/source/RPIO/__init__.py in <module>()
    113 """
    114 from threading import Thread
--> 115 import RPIO._GPIO as _GPIO
    116 from RPIO._RPIO import Interruptor
    117 

SystemError: This module can only be run on a Raspberry Pi!

Thanks for the detailled report. Will look into it.
