LPC 2138 won't verify

[jfw1102]

I am programming on an MCB 2130 LPC 2138. The first time it flashed and the program ran. Subsequent attempts to flash come up with an error verifying. It seems like nothing is being written or erased from the flash. I have the jumpers arranged correctly. Is there something on the board that is preventing writing? I can look at the memory through Flash Magic.

Any help would be appreciated.

Putting 900 into the oscillator allowed the program to be verified.
