Hello,
I am using the F28004x from the C2000 family from TI.
I have been programming the ePWM using the Simulink blocks to achieve the next 4 signals.

First, I did a test model as shown in the next image.

It was working perfectly, but when I added it to the controler to these ePWMs the phase shifted signals stopped working.

I have tried to debug with Code Composer and all the modified registers were properly working for all different ePWM (included the shifted ones).
Any idea of what is happening?
Thank you so much.
