Archlinux on Rock5b

[Benno]

It seems to have stopped working. I had been using fanctrl-rock5b to control the fan on my board. The program panics now. I’d also tried following the old radxa wiki instructions on how to start the fan from the shell and I get this error message from the first command:

echo: write error: device or resource busy

I’m thinking that at some point, the way that the fan is supposed to be accessed was changed. The procedure is different in the new radxa wiki. So, I guess I could modify fanctrl-rock5b, and get it to work again. Also I’ve noticed that I can’t change the way that the blue led flashes anymore as well.

In most newer kernels (5.10.160+), the fan is controlled via a kernel driver, not a userspace script.

[Benno]

Which kernel driver?

[incognito]

Is there a name for it? If there is, I don’t know what.

Dear boogiepop,

I got a kodi compiling error and can’t find the solution (missing package?)
(OP5B, OP ArchLinux Kernel 5.10 +Xfce v4.18, Using java7 for compiling now)

agr install kodi-mpp-git

The compiling error

The fan is enabled with the rock 5’s dtb and being managed by Linux’s fan kernel driver.

Check amazingfate’s post, it was also mentioned before in this thread.

Guide on how to customize you pwm fan curve

Now the new kernel has used pwm-fan kernel driver to deal with the fan control, so the old pwm fan scripts won’t work. Here is a guide on how to customize your onw pwm fan curve since different cases/environment/fans need different fan curve. I will take armbian’s kernel as example because I use armbian as my daily use os. But it will be similar if you’re using official radxa’s kernel, radxa’s kernel uses different cooling levels. If you take a look at the devicetree of rock5b, there is a node…

Any news for the panfork driver for the 6.1-panthor kernel ?
Panfrost performance is not really sufficient.

[Schnabulator]

Hey guys,
do any of you know when the panthor release in mainline is planned? 6.9 or 6.10.
And last but not least thanks for all the work and support here

greetings

Hi, I was wondering if someone could help me. I’ve been trying to update system and as systemd gets updated, it triggers a glibc_2.39 not found. Does anyone how to fix this?

[spikerguy]

Who ever provided this archlinux pkgs needs to rebuild the whole pkg list as the base pkgs are updated.

gcc 14.1 binutils 2.42 glibc 2.39. got updated

[Eric_Woudstra]

Did you do:

sudo pacman -Syu

?

[Mangled]

Yes I ran that. I can’t seem to boot into BredOs once the update is done. However its good I made a backup. If I remove the drive, I was able to restore my data from another PC.

[Eric_Woudstra]

I recently got similar errors, when I did a partial upgrade, which officially is nor supported.

[Mangled]

How do you know if your doing a partial upgrade? Most often I’ve been running pacman -Syyu. Then I recently found out should rather be doing -Syu. Would this make a difference? Neither work for me either way. I still get the error after systemd updates.

[Eric_Woudstra]

-Syu is OK. I did just install 1 package with -Sy.

Maybe the mirror you are using is not synced yet? Try another mirror (and 1 time -Syyu)

[rippanda12]

I personally dont have this issue i updated recently on a few machines. could it be an old mirror?

[Mangled]

Thank you for your help. I’ve tried a different mirror and still have the same issue. I think I may just have to reinstall the OS.

panthor was mainlined in 6.10 kernel

[radtech]

Just burned and installed kwankiu Arch-nodesktop with collaborra kernel 6.9.rc1. Can I get a 6.10-rc3 to test panthor X and wayland on KDE6. Better yet a stock mainline rc3 would be best since thats what will be used soon by most arm distros for Rock5b.

Also Installed full xorg with startx accelleration working after installing libmd and libbsd.
It took awhile for arch to install after some installer hiccups it fixed itself. Overall not too bad since it did leave me with a decently configed base for KDE eventually.

collaborra kernel 6.9.rc1. Can I get a 6.10-rc3

Collabora kernel is at 6.10-rc1 now…
