I am using an EPM900 emulator to debug a LPC935 application that uses serial output. However, I get nothing in any of the serial windows of uV4 when I run it. I decided to start at the very beginning and loaded the "Hello" example project. Under simulation it works fine and I get the "Hello World" message repeated ad infinitum in the UART#1 window. Under EPM900 emulation it downloads fine and the LEDs flash correctly and the printf(..) instruction is being executed. However, I get nothing in any of the UART windows, including the Debug (printf) viewer. As an aside issue, why does uV4 need 3 UART windows PLUS a Debug (printf) window?
I just wanted to point out the issues with baudrate.
Have you tried an oscilloscope to verify what serial data the chip sends out from the UART, before you transfer the serial data to your PC?
