How to output debug message to VCOM(OM13093)

[kimhorng]

Hello,

Does anyone know how to send debug message to VCOM?

I have a OM13093 board, and already short the R30 and R29, and my laptop can get the VCOM.

But I still can't get any debug message.

I used LPCopen and printf() function.

Thank you.

Kim

Update the status,

I can send message to VCOM by Chip_UART_SendRB(LPC_USART, &txring, inst1, sizeof(inst1) - 1);

And send message to Debugger Console by printf when add DEBUG_SEMIHOSTING and set library to Redlib(semihost).

I was wondering if I can send message to VCOM by printf.

How can I do it?

Thanks you

Kim
