hello_world.c Posted November 15, 2018 Share Posted November 15, 2018 There's this: Anybody knows about the status of PWM on the H5 (OPi PC 2 in my case) with mainline kernel? BTW am I off-topic asking about H5 in this forum? Thanks. Link to comment Share on other sites More sharing options...

It works on A64/Pinebook (LCD brightness). It should work on H5 but I haven't done any tests. DEV branch (4.19.y). Link to comment Share on other sites More sharing options...

Looking at my OPiPC2 with 4.19.2, it is present in DT, but with disabled status by default : pwm@1c21400 { compatible = "allwinner,sun8i-h3-pwm"; reg = <0x1c21400 0x8>; clocks = <0x10>; #pwm-cells = <0x3>; status = "disabled"; phandle = <0x57>; }; So, you need to add the PWM overlay in /boot/armbianEnv.txt : overlays=pwm BTW, this overlay is connecting PWM to PA5 ...
