RTOS/AM4377: HRPWM support in ePWM module

Part Number: AM4377


Tool/software: TI-RTOS

Hi,

I am running into problems, when trying to adapt PWM frequency with eHRPWM. I am using AM437x processor.

I was referring to TRM (am437x) for the eHRPWM and it is mentioned that there are some instances that include a high resolution sub-module that allows more precise control of the PWM outputs.

I am configuring PWMSS0 , to get the waveform from EPWMxA, But I am not able to get any waveform. I verified the signal for EPWMxA and its coming always high.

I believe  eHRPWM is only available on PWMA channel,please correct me if I am wrong  and please provide any sample code if possible. 

Thanks in advance.

Regards
