Continuing tests of distribution installers. This time I installed Fedora ‘rawhide’ from netinst iso (2020.06.20). Fetched, wrote to USB pen drive and booted. Due to U-Boot being present in on-board SPI flash I did not had to mess with installation media.
Issues
There were some issues:
- Panfrost failing to initialize
- U-Boot unable to load grub efi
Panfrost initialization failure
Panfrost kernel module needs some devfreq governor. Kernel has four of them, Fedora enables one. There are no dependencies between those modules which ends with the same error as with Debian:
panfrost ff9a0000.gpu: devfreq_add_device: Unable to find governor for the device
panfrost ff9a0000.gpu: [drm:panfrost_devfreq_init [panfrost]] *ERROR* Couldn't initialize GPU devfreq
panfrost ff9a0000.gpu: Fatal error during devfreq init
panfrost: probe of ff9a0000.gpu failed with error -22
Solution was the same as before — boot without ‘panfrost’ module. I interrupted
grub from starting and added rd.driver.blacklist=panfrost to “linux” command.
This allowed me to boot into Fedora installer and system installation went smoothly.
First boot on installed system shown working Panfrost driver:

U-Boot can not load Grub EFI
After reboot U-Boot was not able to load Grub from EFI System Partition:

How to work around it?
- connect your Fedora storage into other computer
- copy “/efi/fedora/grubaa64.efi” to “/efi/boot/bootaa64.efi”
This way U-Boot will get grub efi binary to load in default location.
Final effect
Board boots directly to graphical login manager and then to GNOME3 session. Extreme Tux Racer and Xonotic worked out of the box. Speed-wise it feels slower than KDE Plasma session on Debian.
