no answers at all? or have you overlooked me? Greetings

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 armbianmonitor.txt

Addendum to Rock 5B, Fan Control doesn't work: Armbian support file attached I would assume the problem is with access rights...? Probably the "Others" group also needs to be given write and execute rights to permanently change the policy to "step_wise"?
