Greetings!
I am working on Rock 3A and using ubuntu 20.04 version on that. I’ve connected POE hat on the board, and installed libmraa and poe dependencies. Restarted the rockpi-poe service. But the issue is the fan continuously running even after changes made on poe config file. I checked the service again and got below mentioned error.

Can you please help me with this issue?
I checked my uEnv.txt file also. I mentioned the overlays, please check whether it is correct or not.
