feature request..... info request.... Fedora ARM support

[jacksnodgrass]

Trying to see how the Fedora ARM stuff works. I run this ( and a different php gpio that I found ) and it complains that:

sh: line 1: /sys/class/gpio/export: No such file or directory
sh: line 1: /sys/class/gpio/gpio18/value: No such file or directory

some gpio stuff is missing. I think that it's ok on Debian.... I know that the /sys/class/gpio/export file/dir exists at least.

Is Fedora ARM just broken / not there yet as far as the gpio support goes?

Hey @jacksnodgrass,

To be honest, I'm not too familiar with running Fedora on the Raspberry Pi but I suspect that you may need to install GPIO support or obtain a build that contains GPIO support for the Raspberry Pi.

EDIT: I just found this post (https://discussion.fedoraproject.org/t/fedora-iot-raspberry-pi-and-gpio-access-in-podman/2153/4) that suggests that Fedora uses a different character device.

Therefore there are a couple of suggestions:-

1. You could try symlinking the standard (eg. /sys/class/gpio) required paths to /dev/gpiochipN.
2. See if there is a way for you to install a backport with this support into your existing Fedora installation.
3. Switch to a distribution/flavor of Fedora that supports the /sys/class/gpio character paths.
4. ...give me a few weeks (as I'm super busy at the moment) and I'll bake optional support for these paths.

Hope this helps :)
