Hello! I'm quite new at LPC21XX world and in the beginning I stumble at UART0 problem. I can get it right. I copied example program from Phillips site, try to correct it and no luck. When ever I try to program my KEIL MCB2140 board with ULINK and have UART0 connected I get "NO JTAG device found". Can any one help me on that? Best regards, Karl
Might be that you disable the JTAG interface by accident. Take a look to: http://www.keil.com/support/docs/2993.htm
