Dear @royk, Thank you very much for your prompt response and assistance! Your suggestion indeed helped me resolve the issue with PWM on my Orange PI 5 Plus. I also wanted to mention that I am using the Go Lang Periph library, and the error message “pwm is not supported via sysfs” originates from the library itself, indicating that PWM functionality has not been implemented. A clearer error message such as “not implemented” would have been more helpful. Once again, I truly appreciate your help in resolving this matter.

Dear Armbian Community, I hope this message finds you well. I am encountering an issue with PWM on my Orange PI 5 Plus running Armbian. Despite my attempts, I am unable to utilize PWM via GPIO pins. Upon navigating to /sys/class/pwm, I can only see the pin designated for controlling the fan. The PWM pins on the GPIO are not visible. I have successfully controlled GPIO pins using WiringPi and Go Lang Periph libraries; however, when attempting to use PWM via GPIO, I encounter the following error: I have also checked the “hardware setup” screen in armbian-config, where I can see two hardware components listed, but PWMs are not among them. For your reference, here is the output of armbianmonitor -U: https://paste.armbian.com/uvejirijen.yaml I would greatly appreciate any guidance or assistance on how to resolve this issue and enable PWM functionality on my Orange PI 5 Plus. Thank you very much in advance for your help.
