LPC54114 Example Projects use the same USART as the debugger.

[billcarpenter]

I'm using the LPC54114 development board and the MCUXpresso IDE. I downloaded the SDK for the board. All the example USART projects are written around USART0 but the debugger also uses USART0. The output pins P0.0 and P0.1 never show activity. How do I get around this?

Hi Bill

I just tested NXP LPC54114 board debug interface is also VCOM， it connects with LPC54114 uart0. see it in board schematic.

when you connect computer with debug interface, you will see VCOM shown as below:

Please check which COM number is assigned to your USB VCOM. I tested one of our demo board, there is no problem to send/receive data via COM53.

But please make sure SDK debug console is UART, with Quick settings, you can set UART console

Have a great day,
Jun Zhang
