Couple of newbie questions (LPC2294)

Couple of newbie questions (LPC2294)

2006-04-04 by flocheckv10

Hi,

I recently bought the IAR kickstart kit for LPC2294 (came with a 
phytec board, PCM023 header + HD200). I hope someone can help me 
answer these questions..

1.

When I try the philips LPC2000 flash utility I get the error "can't 
communicate with target board". There are two buttons on the HD200 
board, one reset and one boot. Isn't it correct that I can force the 
chip in ISP mode by pressing both and releasing in the order reset, 
boot? I have tried various communication speeds (still there is auto 
baud detection so shouldn't matter) and different serial cables, but 
the problem remains.

2.

With the kickstart kit I got this J-link debugger. With this one I 
can start a debug session in internal flash/ram. My question here is 
about the program signature. Do I have to add it myself or does the 
J-link do that for me? The reason I ask it that if I stop the debug 
session and recycle the power to the board my program is not 
running. Tried with the Blinky sample app (simple LED flashing 
program).

3.

When it comes to external flash (4Mb mounted on the PCM023). Lets 
assume I want to program this with a serial cable from a stationary 
computer. As I understand it right now I have to write my own 
flashloader that must be uploaded to internal flash/internal RAM 
first (by the LPC2000 flash utility for example). Then I can 
communicate with this new flash loader with some other serial 
program to write external flash.

4.

What is the correct output file format from IAR for the LPC2000 
flash utility. I have tried project->options->linker->output format 
to "intel-extended" and format variant "none" and in output file I 
have override default checked and changed the name to .hex. Since 
the flash utility does not work (see question 1) I can't say if this 
format will work, will it?

Thanks
