error when using GPIO from Python

[dcatteeu]

Hi,

I have a docker that runs a Python application which uses GPIOs (via the Python RPi.GPIO library).

This docker runs fine on the Raspberry Pi 3B, but not on the netPI. I get:

Code:

RuntimeError: No access to /dev/mem.  Try running as root!

Further information:
- I do start the docker container with the `--priviliged` option.
- I have not yet attached a DI DO extension the netPI. I assume the module is "just" extending the GPIOs to the outside.
- On the Raspberry Pi, I don't use portainer.
- I've upgraded the firmware of the netPI to the latest version on September 5.

Are there any differences between the netPI and Raspberry Pi concerning the GPIOs or am I doing something wrong?

Thanks,
david.
