Probably my need seem's curious but in our process it's usefull.

I need to modify a const value in the binary program before flash it in the LPC1768.
This value is a customer code and crypto key, and in production we have to put it in the FLASH for security reason.

I want : In production they take the axf, change the code and key, and program the flash (we have made an internal tools for automate this tasks).
But i don't understand the axf format and i don't find in it my constant !

Does anyone have a suggestion ?
Or an advise for help me ?

Thanks a lots, Philippe.
