I suspect you'll need to post a minimal demonstration, and see if any other G4 users can confirm or refute.

Strikes me that the HW should be capable, check the channel relationships, and register level configurations when the issue occurs.

Is "rubbish" associated, pattern wise, with what the other UART is sending? Do you have any more specific analysis/observations from a scope or logic analyzer?

Sorry i am still testing but so far i can see was de problem in my wiring diagram and not in de processor.

On this moment everything is working correct.
