Radxa zero 3W PWM

Hi,

I’m trying to use the PWM pins to generate PWM with no success.
Anyone have a working example?

Please look at: https://docs.radxa.com/en/zero/zero3/app-development/mraa

Can anyone tell me are PWM drivers available in Kernel 6.1 of Armbian 'NOBLE` I simply cannot get PWM pins of RADXA RK3566 to work. In details my effort Zero 3E PWM GPIO under Kernel 6.1 Ubuntu
