Lpc2000

I have the olimex LPC-P1 board & I'm evaluating the crossworks system.

I placed a breakpoint on the first code of line in my main procedure 
and the debugger stopped at this point, the debugger is working and 
allows me to step/watch/etc.  

If I let the software break at this instruction and don't do 
anything, after a while the view switches to assembler and it appears 
to have jumped off to an exception vector, for example data abort, 
without me actually doing anything.

I can't get their uart example working properly either, I modified 
the cpu frequency so that it is correct.  If I single step through 
the uart initialisation (assuming I make it all the way through 
without it not jumping to an exception handler) and then run, I get 
all the "hello worlds" on the serial port.  However, if I just run 
the code without single stepping the initialisation then I get random 
sequences of "H" "L" and "."....

So, I decided to try gdb, I downloaded the 2 packages for windows 
from the mcgraigor site.  When I run the "ocdlibremote -c ARM7 -d 
WIGGLER -a 1 -s 8" I can get gdb to connect but it doesn't work and 
usually results in gdb stopping.  If I try any speed other than 8 I 
can't get it to work.

Anybody got any ideas about what's going on here?  I really don't 
know what to do - other than trying another pc.

Thanks.
