My project runs when connected to the LPClink, but won't run standalone when I disconnect the LPClink.

I'm guessing at a watchdog timer reset. Trouble is, I don't know where the watchdog reset is occurring.

What's the best way to find out?
Is there a better way that to watch the outputs on an oscilloscope?
Is there a way to switch on the watchdog whilst debugging?

Any suggestions gratefully received!

I don't need the watchdog (I only used the LPC1225 because the pins are arranged in a sensible order!)
I tried unsuccessfully to switch it off.

This paragraph (on the WDEN bit) puzzles me:

"The watchdog timer is running. The watchdog timer is automatically enabled
at reset without requiring a valid feed sequence. Any subsequent writes to
this bit require a valid feed sequence before the change can take effect."
