Andrea Posted February 21 Posted February 21 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! 0 Quote
ning Posted February 22 Posted February 22 what's charge pump, is there devicetree yaml to let you know how to use pwm? 0 Quote
Andrea Posted February 22 Author Posted February 22 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). 0 Quote
