Missing TI AM3352 PWM drivers

#1 Post by I am a nobody »

Hi,

I built a TI image running on TI AM3352 MCU, my dts file includes am33xx.dtsi which defines all enhanced pwm:

epwmss0: epwmss@48300000 {
...
};

epwmss1: epwmss@48302000 {
...
};

epwmss2: epwmss@48304000 {
....
};

But the PWMs are missing:

$ ls -l /sys/class/pwm
total 0

What could I be missing?

Thank you.

Kind regards

Texas Instruments seem to have forums for their processors. Maybe try a search there or ask a question. There is mention of Linux drivers provided on git.kernel.org.
