I'm trying to use the ehrpwm.2: 0 and ehrpwm.2.1 that are assigned to P8.19 and P8.13 respectively Pines, I have sent to Mode 4 without problems.

The problem is that when I go to /sys/class/pwm only there are ehrpwm.0:0 ehrpwm.0:1 ehrpwm.1:0 ehrpwm.1:1 NOT EXIST ehrpwm.2:X , then there is no such set the parameters of the pwm like duy_percent, run, stop, etc.

 

Can you help me please????

    Hi Julio,

    Are you still facing the problem

    What processor are you using like am335x or any other?

    What is the SDK are you using?

    As you said you have set it to mode4 in pin mux, have you enable pwm in board file.
