Banana Pro, PWM control

[zgoda_j]

In my /boot/config for 3.4.112 I have CONFIG_SUNXI_PWM=y yet there is no /sys/class/pwm-sunxi directory. Do I need to do anythig special to control onboard PWM? This is stock Armbian 5.16 with legacy kernel.

You probably need to add pwm0_para section to your FEX file like this

[pwm0_para]
pwm_used = 1
pwm_period = 20
pwm_duty_percent = 50

Don't forget to recompile it to .bin afterwards.

Thanks, that was the missing part.
