Raspberry Pi 5: invalid GPIO 9

[igo]

Hi,
after migrating to RPi5 from RPi4 I cannot run mysgw:

pi@pi:~/projects/MySensors $ ./configure --my-transport=rf24 --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mysgw1
pi@pi:~/projects/MySensors $ make
pi@pi:~/projects/MySensors $ sudo ./bin/mysgw 
Aug 27 15:16:32 INFO  Starting gateway...

Aug 27 15:16:32 DEBUG TSF:WUR:MS=0
Aug 27 15:16:43 ERROR Could not open /sys/class/gpio/gpio9/direction

Any idea what is happening or how can I debug it? I found this which says "raspi-gpio is deprecated and doesn't support Pi 5".

@igo
Is it resolved?

@igo As you may be aware, MySensors is not well supported these days. In fact, the support comes from people like you and me who still find value in MySensors.

That said, search for a replacement for raspi-gpio. There may be a few. See if they work. It's important to the MySensors community that you report your success or failure to do so.

I've done this sort of thing before and learned a lot from the experience. Let us know how it goes!

https://github.com/mysensors/MySensors/pull/1562 switches to using libgpiod instead of the earlier interface. I have not tested it myself but it looks good.
