Portenta PWM issues

Official Hardware Portenta Family Portenta H7

I’ve had issues with my Portenta H7 running PWM on a couple of pins.
I notice that more people have same issues, but see no reply.
The issues are regarding cross-feed or similar between the USB-C port and the PWM for pins D1(PK1), D3(PG7) – PWM on this pin freaks the Portenta out, and D6(PA8).
For D1 and D6 I can see cross-talk of some kind when I have the USB-C connected. If I power the Portenta through the breakout carrier only, there are no cross-talk on the PWM output associated with PK1 and PA8. I use the portent pin numbers because the documentation seems to be a bit confused of what it’s supposed to be. :roll_eyes:

I made a video in case its easier to follow the issues there:

I have noticed the same issue. Very disappointing. I spent $150.00 US on this "professional" grade product and cant do the same projects I can do with a $10.00 ESP32. Documentation is sparse and sloppy. They really need to jump on this problem or tell us how to get our money back.

Would you like to try the new PWM examples of my new Portenta_H7_TimerInterrupt Library to see if it's better ?
