OrangePi Zero 2 H616: PWM support

Andrea
in Allwinner sunxi

Featured Replies

Hi all,

 

  I would like to use the PWM1 in order to drive a charge pump, but I am struggling to enable PWM using the DTB on Armbian v23.11.

 

Anyone succeeded in configuring PWMs in H616?

 

Thanks in advance!

    Charge pump is a very simple topology of DC-DC switching converter, normally driven by SoC PWMs. I have checked the DT yaml, but could not find anything useful.

     

    I found a PWM driver for Allwinner H6, but it does not work (I get error -22, EINVAL when loading the driver module).
