I have just received the Olimex LPC-H2103 board from Spark Fun and I’m having some trouble getting started.
Out of the box both jumpers are installed. I applied +5V to EXT2.17 and GND to EXT2.19. The power LED comes on and the other LED turns on, off, then blinks rapidly. So far, so good, now I want to program the part using the Philips LPC2000 Flash Utility V2.2.3.
I attached the Spark Fun RS232 Shifter to +5V, GND, P0.0(TXD0) and P0.1(RXD0). Then I connect P0.14 to GND and power or reset the board. In either case the power LED turns on but the other LED stays off. That makes me think the LPC2103 is in ISP mode. However, the Philips Flash Utility will cannot talk to the board.
The Flash Utility is set for the correct COM port, 9600 baud (though I believe it will autodetect), and XTAL freq 14745 kHz. When the util tries to talk to the board the RS232 shifter tx led blinks but not too brightly and the shifter rx led blinks faintly with occasional bright flash. Once the utility times out the shifter’s tx led goes off and the rx led stays slightly illuminated. Now I’m lost.
Can anyone help?
