    Is the CM4 debug UART routed to the USB connector?


      I was following the UART Bare metal sample and trying to see the output from


          Uart_Init(UartCM4Debug, NULL);
          Uart_EnqueueString(UartCM4Debug, "--------------------------------\r\n");
          Uart_EnqueueString(UartCM4Debug, "UART_RTApp_MT3620_BareMetal\r\n");


      But I couldn't see it nowhere in the VS output windows.

      Also tried to connect TeraTerm to all 3 COM ports associated with the SDK and I couldn't see the output on any of them either.


      Looking at the SDK schematic it seems that the debug UART is routed to the lowest COM port.

      What am I missing here?
