bootloader for SAM7 parts

Hello, All!

I'm studying SAM7 and going to implement a simple bootloader for sam7s256 and sam7s64 later on. I already checked the application note "Safe abd secure bootloader" provided by Atmel. It's source code is based on IAR compiler, and it's confusing me a lot.

What I don't quite understand now is the concept of remapping. When and where in bootloader design I need remapping functionality? As I understood, booting code, which is responsible for uploading image via RS232 or, for example, USB doesn't need to be remapped, but application being uploaded is needed.

Am I correct?

Would appreciate any hints and help! Thanks.
