About this Howto

This documentation is about using Raspberry Pi Foundation downstream kernel and components from Fedora userspace. The Workstation flavor is recommended for the Raspberry Pi 4 B/400 with >=4GB RAM platform. The Server flavor is usable on starting from Raspberry Pi 3 B/B+.

Kickstart files

Kickstart files are located at https://pagure.io/fork/dwrobel/fedora-kickstarts repository and are based on the original Fedora 41 files with the following modifications:

component	Repositories	comment
kernel	spec / copr	Downstream kernel
bcm434xx-firmware	spec / copr
bcm283x-firmware	spec / copr
pykickstart	PR / copr	Adds --priority=<priority>
livecd-tools	PR / copr	Adds support for repository 'priority' configuration

The modifications in livecd-tools and pykickstart allows to generate image with selected downstream kernel (despite it has lower version) over the upstream one. On a system, all aforementioned repositories are installed with priority=50 option to instruct 'dnf' to choose packages from this repository, rather then Fedora default.

Pre-built images (f41)

The location of pre-generated images for Fedora 41 can be found below:

Pre-built images (f40)

Updating Raspberry Pi 4 bootloader EEPROM

Follow the gist available at: https://gist.github.com/dwrobel/266ad5d4e59b05ea26d8bb6725118578.

Raspberry Pi 5

Despite that Rasberry Pi 5 is not supported, images for F41 are reported to work with the following content appended to the /boot/config.txt file:

[pi5]
# Automatically load overlays for detected cameras
camera_auto_detect=1

# Automatically load overlays for detected DSI displays
display_auto_detect=1

# Enable DRM VC4 V3D driver
dtoverlay=vc4-kms-v3d

# Allows the default turbo-mode clock to be increased from 1.5GHz to 1.8GHz
# Based on https://www.raspberrypi.com/documentation/computers/config_txt.html#arm_boost-raspberry-pi-4-only
arm_boost=1

disable_overscan=1

Note: Basically it is the [pi4] section duplicated as [pi5].

Configurations

Booting from external USB drive

Write the image to the external drive, then mount the filesystem and change root=/dev/mmcblk0p2 to root=/dev/sda2 in the /boot/efi/cmdline.txt.

Note: On the Raspberry Pi 4, you may need to adjust BOOT_ORDER= parameter in order be able to boot from the external drive.

Resizing filesystem

After booting the system, please consider to resize the filesystem. The following example assumes system booted from internal SD card.

sudo growpart -u on /dev/mmcblk0 2
sudo btrfs filesystem resize max /

-This documentation is about using Raspberry Pi Foundation "downstream kernel" and components on a Fedora (or CentOS) userspace.
As with Fedora, this process is compatible with Raspberry Pi 2 and later model (No original Raspberry Pi or Pi Zero support is planned).
Unless using a Raspberry Pi 4 with 4G of RAM. It's recommended to use the 32bit version over the 64bit (especially for the Workstation flavor).
For graphics usage, it's really recommended to have a Raspberry Pi 4 which default to the vc4/v3d driver.

== Known issues ==
 * uboot-tools prevents clean update of kernel packages
The "/usr/lib/kernel/install.d/10-devicetree.install" script from uboot-tools package prevents older kernel packages from being removed cleanly during update:
{{{
  Erasing          : kernel-core-5.10.35-1.rpi.fc33.armv7hl
warning: file /lib/modules/5.10.35-1.rpi.fc33.armv7hl/modules.builtin.alias.bin: remove failed: No such file or directory
}}}
To mitigate it run the following command:
{{{
$ echo "FIRMWAREDT=True" | sudo tee /etc/u-boot.conf
}}}

 * There is a CMA memory allocation issue with graphics on the Pi3 using vc4, best is to disable vc4 (will be un-accelerated).
