Does the poke example work when the JTAG programmer is removed, and you use a USB to serial adapter to talk to the programmed LPC2148 board?
I can see from minicom that the RS232_0 serial port is outputting data. Button presses seem to produce output also. However, the board isn't echoing anything I type at it, so I'm concerned the board can't hear me. The screenshot shows a serial only connection, but I can't use a straight serial cable because my host PC doesn't have a serial port. Suggestions?
