CAN Bootloader for MC9SXEP

Hi everybody,
i'm new of this group.
I've to do a CAN bootloader for mc9s12xep100 microcontroller i've read AN2546 and AN3391 application notes but at this moment i'm a little confused.
Some of you have already write a bootloader for this family? Can you explain the step i've to do to write a bootloader?

Thanks

In my opinion AN2548 is more useful. AN2720 is a distillation of the flash programming routines but isn't a bootloader (no reset management or real/pseudo vector tables). You probably want something in the middle.

V2.03 of the software works with xgate.

I have a version of the AN2548 bootloader for the S12XE. I'll attach it.
It's a CW project.
