Hello everyone,
Hello everyone,
I have installed Armbian Bookworm 23.11.1 (kernel 5.10.110).
The fan control does not work. The fan only runs at level 1. None of the many patches I tried worked.
The last one tried was this: https://forum.radxa.com/t/guide-on-how-to-customize-you-pwm-fan-curve/17442
I can adjust the fan manually, but the automatic doesn't work. The "policy" file (/sys/class/thermal/thermal_zone0/policy)
cannot be permanently changed to "step wise" (logged in as root).
After restarting it is back to "user_space"...
The access rights are:
-rw-r--r--1 root root 4096 Feb 11 02:42 policy
Owner: = Root Root: = rw
Other: = r
I would assume that the problem lies in the access rights...?
Probably the "Others" group also needs to be given write and execute rights to permanently change policy to "step_wise"?
How can I change the "policy" file so that step_wise is retained even after a restart?
Or could it be that inheritance plays a role in the access rights - and therefore it is not the rights of the "Policy" file that need to be
changed, but rather those of the parent folder "thermal_zone0"?
How can I change the “policy” file so that the “step_wise” setting is retained even after a restart and the fan control works?
I would be happy if someone could help here.
Greetings
