Hope someone can help...
I use the keil development system and I use Flash Magic V4.18.1224 to program my prototypes. Flash Magic works great, I have no problems here.
I want to have AvNet program my LPC2194's for me before they are soldered to the PCB. I sent them the same .hex file I use with Flash Magic but it does not work. After some poking around the memory locations using FM I found that 4 bytes starting at location 0x14 were different between a working and non-working board.
The memory dump of the non-working chip matches exactly the .hex file I sent Avnet. The working chip that I used FM to program has 4 bytes changed from the .hex file that is loaded into FM.
Works:

Does not work:

Why does my .hex file not work with Avnet's production programmer?
And what is FM doing to the four locations to get the .hex file to run properly when using FM?
I've been trying to figure this out by myself for the better part of a day now and I'm getting no where.
Much thanks for anyone who can help me out!!!
