RPi.GPIO is not working with CM5 Module - many plugins broken with PI5 generation

What is the problem?

I exchanged my Raspberry PI 4b with a CM5 Module to get a SSD and also ext. Ant. With OctoPI 1.1.0 (beta) created also for CM5 modules it breaks GPIO functionality of many plugins like enclosure or GPIO-Status. This seems caused by the standard library RPi.GPIO that is not enhanced anymore but not sure if that is 100% true as I cannot get it running again installing drop-in replacements.

Created a ticket for OctoPI as a workaround should be integrated there if possible to support old plugins out-of-the-box. CM5 or rPI 5 GPIOs are not supported because RPi.GPIO lib does not support it · Issue #848 · guysoft/OctoPi

What did you already try to solve it?

Tried to install an drop-in replacement like GitHub - phylax2020/RPi.GPIO: RPi.GPIO wrapper for WiringPi or RPi.IGPIO on system level with APT and also in the venv with PIP without success.

Have you tried running in safe mode?

No, as it is related to the plugins or e.g. Debian (OctoPI) installation.

Did running in safe mode solve the problem?

Additional information about your setup

OctoPrint 1.10.3, OctoPI 1.1.0 beta - build 10.03.2025, Raspberry CM5 Lite

This is definitely something that needs to be dealt with on the plugin side of things. You mention you tried to install the drop-in replacements, but did you attempt that in OctoPrint's venv?

source /opt/octopi/oprint/bin/activate
pip uninstall RPi.GPIO
pip install rpi-lgpio
deactivate

then restart OctoPrint.
