Lpc2000

This occurs when I jump to main (C code) from the startup code (Keil).
 I have added files to this project from one based on an 8051,
modifying them of course to compile.  Before I added the files I could
debug with no problems.  They also include several header files.  
I can step through the assembly code in the startup file but as soon
as I step past the branch to main I get a data abort. 
I am hoping this will ring a bell for someone in the group.

Thanks

Rich
