Lpc2000

I have been using the Nohau debugger for my project. All the code does
is toggle a port. The code works fine while in debug mode, but when I
pull the DBGSEL line low, and reset the part there is no code
execution.

When I read the flash, it verifies with the code, and if I remove the
pullup and debug dongle while the debugger is "running", the code
continues to execute. However as soon as I reset the part, I loose
code execution.

Anyone seen this problem?

specs:
--------------
part: lpc2104
board: My own
Debugger: Nohau SeeHau
compiler: arm-elf-gcc.exe

A couple of sanity checks
         1 - You have checked that DBGSEL is indeed low?
         2 - Have you checked that P0.14 is high?  If not you may be in 
bootstrap mode.

Thank you.
  I missed the P0.14 altogether. I was reading the wrong Users manual.
  Pulled it high, and it solved the problem.
