M203 clean evok install not working

rob

Hi,

I bought an M203, and flashed the official UniPian Neuron OS image available here
Trying to access the web interface showed an empty list of inputs and outputs, nothing was working:

So I tried an apt-get dist-upgrade followed by a manual installation of latest evok 2.0 as per instructions available here

Rebooted, I get the same result.

Here is the log I get when launching evok manually as instructed in the debug section of the documentation:

^C[I 180106 15:58:07 evok:1779] Shutting down

Is there something wrong with my hardware? It seems to me the RPI can not communicate with the internal plc boards.
Or is it a configuration mistake? What could I possibly have done wrong?

I'll be very grateful to anyone who could shed some light.
Thanks!

Quick update:

I repeated the Evok installation as per the instructions above on a clean vanilla raspbian stretch image taken from the official raspberry pi repo (not the UniPi customized one) and everything works fine.

Thus - there seems to be some misconfiguration in the official UniPi image, at least when used with M203: beware.
