Sometimes it is simpler as you thing!!

To philips_apps:
There is an error in the LPC2114/2124/2212/2214 USER MANUAL(date
2004-05-03) 
 - On page 33 figure 2 it shows the LPC 2124 in the block of devices
with 128 kB flash!! It has 256 kB. 

In my example Sector 14 and address 0x1C000 didn't fit for the LPC
2124 doing IAP and resulted in Status Code 9
SECTOR_NOT_PREPARED_FOR_WRITE_OPERATION.
