Raspberry CM3 module unsupported. #112

I installed RPIO (branch v2) on an ACME System CM3-panel board running the last Raspbian Lite available. As per the name, this card is powered by a CM3 module (lite). Running the rpio --sysinfo, I get this error:

pi@cm3panel:/tmp/RPIO $ sudo rpio --sysinfo
Traceback (most recent call last):

KeyError: 'a020a0'

Looking to the code it seems that such revision code is not considered at all into the code. So, I forced in cpuinfo.c to return 3 but no joy, the examples seem to work but I cannot measure any PIN voltage change.

Probably the ID to PIN table should be reworked as well. Any suggestion on where info about this mapping can be found?

Hey,

Did you manage to fix this?
