by Peter Robinson
Hi René,
I've copied the Fedora arm list, please email the list or post on the
Fedora forumus in the future, it allows others to reply as well as
learn from replied.

TBH I had never heard of pigpio until you just mentioned it now.

The main way we support GPIO on any device in Fedora is via the gpiod
character interface: /dev/gpiochip*
The main userspace libaries for this is libgpiod and python3-libgpiod
but anything that supports the kernel gpiod character interfaces
should work.
The problem with a lot of the RPi specific interfaces for GPIO is that
the RPi has uses an old deprecated GPIO interface with their own
custom set of patches on top. We don't support those.

CoreOS on NanoPC-T6 (RK3588)
by Waldemar Kornewald
Hi,
did anyone succeed booting a FriendlyElec NanoPC-T6? Since there was some success report with Radxa Rock 5B recently, I was hoping that the NanoPC-T6 wouldn't be too different.
So, I tried CoreOS 40 with EDK2 (https://github.com/edk2-porting/edk2-rk3588) and the Linux 6.7-rc2 rk3588-nanopc-t6 device tree placed in the ESP. While ACPI didn't want to boot at all, the device tree boot at least spits out some more logs. However, the system just abruptly disappears in the end: https://pastebin.com/zqs7nQ8L
I also tried Fedora 40 (Minimal), but that runs into a CPU lockup: https://pastebin.com/aafvP6du
In both cases the OS image was copied to eMMC while EDK2 was on an SD card.
Any ideas why the NanoPC-T6 doesn't want to boot?
Greetings,
Waldemar

Re: Possible deprecation/removal of Initial Setup from Fedora
by Dennis Gilmore
All of the Arm disk images use initial-setup to configure the image.
There would need to a concrete plan on how to manage the transition to
something else.

Raspberry Pi 5 support - how to contribute?
by Daniel Miranda
Hello,
I've recently - and somewhat surprisingly - already got my hands into a Raspberry Pi 5. I would like to contribute to make it supported , as the Pi4 is.
I have extensive Fedora experience, but not with ARM, and how the whole ecosystem works. What would be useful to get started with a test image for the Pi5? Or if that's not yet possible, what information or resources can be of use to get to that points?
Thanks!
