Lpc2000

Hi everybody!!!

I'm new in the group. I'm working with an LPC2194 and the uVision3
Keil Software using the GNU compiler. My boot loader version (from the
Flash Utility is 1.64) 

My problem is related with the IAP. I get to write in the flash, but 
the program a few miliseconds later do not work anymore. 

Before writing to the flash I disable all the interrupts. I do not 
disable the PLL when I work with the IAP.

Is there anybody who could help me?

Best regards, Jaime
