lpc2138 taking commands merely as a suggestion?

Started by kosta July 29, 2007
Im working on an embedded project and I'm currently using an Olimex P-
Lpc2138
board. After having the device misbehave badly, I decided to try
something
simpler - to control the leds on the development board.

After seeing what happened, I realized that something is very wrong.

Even very simple code which just turns on and off the leds
repetitively, doesn't
work correctly - sometimes the PLL would fail to lock, sometimes loops
don't
work and cause he code not to run at all...

I compile the code with -O0 optimizations usually, but oddly enough
sometimes
when I try other types of optimization, some work better in making the
leds work
correctly.

Obviously I'm getting very frustrated over this, and I'm starting to
lose
hope... - I can't even get dbg in eclipse to debug the code!

I will be glad to provide any other information which might help
resolve this, I
just don't really know what might be needed - please tell me if theres
anything
else you need to know, and I will promptly provide the info.

Thanks in advance,
Kosta

:-) OK, the board designer is a moderator of that group, so he may get back to you eventually. If he doesn't, try Olimex support.
