Hi Paul,
I have had a problem that seems simular to your though not exactly 
the same.  For a new prototytpe device we are designing we had 8 cpu 
boards manufactured, each with a LPC2114 microcontroller on board. 
Five of the eight boards programmed with no problem using IAR 
Workbench and a J-Link adapter.  The flash on three boards would not 
program no matter what I tried.  As a last resort, I had the LPC2114 
replaced on these three boards and the flash on all three of the new 
LPC2114s programmed with no problems.  Three out of eight bad 
LPC2114s seems very unlikely, but I have no other explanation for 
what I experienced.
Good Luck,
Bob Davis
