<2db66cb8-eb3d-e7cc-03ff-e3538b794c77@disroot.org>Hello, I want to use a RPi power button <https://howchoo.com/g/mwnlytk3zmm/how-to-add-a-power-button-to-your-raspberry-pi> and this requires GPIO <https://pimylifeup.com/raspberry-pi-gpio/>. However, it looks like GPIO is disabled in RPi 4. When I start a relevant Python program I get this error: $ sudo /usr/bin/python3 /opt/fanshim-python/examples/poweroff.py traceback (most recent call last): File "/opt/fanshim-python/examples/poweroff.py", line 12, in <module> GPIO.wait_for_edge(button_pin, GPIO.FALLING) RuntimeError: Error waiting for edge Can you please advise how to fix this issue? This isssue is not reproducible with Raspbian OS (based on Debian). THX Thomas

Can you see gpio in /sys/class/gpio ? Or an overlay might help: https://github.com/raspberrypi/firmware/blob/4fe2e4af02058f88f991469349a335a25a2c719d/boot/overlays/README#L1166 > On 17 Apr 2022, at 15:55, Thomas Schneider <t.schneider@disroot.org> wrote: > > Hello, > > I want to use a RPi power button > <https://howchoo.com/g/mwnlytk3zmm/how-to-add-a-power-button-to-your-raspberry-pi> > and this requires GPIO <https://pimylifeup.com/raspberry-pi-gpio/>. > > However, it looks like GPIO is disabled in RPi 4. > When I start a relevant Python program I get this error: > $ sudo /usr/bin/python3 /opt/fanshim-python/examples/poweroff.py > traceback (most recent call last): > File "/opt/fanshim-python/examples/poweroff.py", line 12, in <module> > GPIO.wait_for_edge(button_pin, GPIO.FALLING) > RuntimeError: Error waiting for edge > > Can you please advise how to fix this issue? > > This isssue is not reproducible with Raspbian OS (based on Debian). > > THX > Thomas >
