Instead of using virtual COM port for PUART I want to connect these pins to extenal UART, which then can be connected to other board. I turned of SW5 to OFF position and connected USB to TTL converter pins as below
TX = P4
RX = P33
5v = 5V_Bus
GND = GND
Before SW5 turn off I verified I am getting trace message on Virtual COM port PUART but after SW5 is OFF I did not
observed any output on terminal.
