Hey struggling with a project - and it’s basic. I’ve got my first u2s HD DAC and I want to use the hardare UART defined as MCU UART on a 3 pin header.
It seems to be completely dead, I receive or can send nothing over the interface. I dove into it and even through a debugger on boot-up, no boot chatter.
Is this not working?
I see a number of posts with folks in the same situation that went unanswered. Is the UART port non operational?
