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
lpc2138 taking commands merely as a suggestion?

If he doesn't, try Olimex support.
