Hi there, im trying to control the epwm6 in the cpu2 of the refered mcu but im not beeing able to do it. In the cpu1 main i assing the gpio muxus to the correct positions ang give the onwership of the epwm6 module to the cpu2. in the cpu2 i enable the clock for the epwm6 and configure it but it dosent work. do i need to give te onwership of the gpio to cpu2 as well?

There shouldn't be any need to assign the GPIO to CPU2, so long as CPU1 has already configured it as required.

I would first try and set up the ePWM6 with CPU1 only, to make sure your configurations are correct. Then try and replicate it using CPU2.

I recall that peripheral clock control with CPU2 has some tricks to it. Look up the CLKSEM register.

Hi,

Thank you! I found the problem. When passing ownership to CPU2, I completely overlooked that it’s an EALLOW-protected register. Adding the necessary lines solved my issue.

Thanks again!
