Own Bootloader / IAP

Hi all,

hope I did not miss a similar topic here. I searched, but did not find anything appropriate.

I want to have my device (LPC2368) to be updatetable via USB. To accomplish that, I think about two separate applications, a simple + small USB program (as H I D device, located at adress 0) that, upon reset checks for an USB link and, if none exists, starts the second "main" application, starting at address, say 0x8000.

Upon an USB connection at startup, the bootloader would erase/program the flash using IAP.

How do I have to set up uVision/the linker to build this application
a) at adr 0 for debugging / test purposes
and
b) at the higher address for release versions

any tips highly appreciated
kind regards + thanx in advance
