Dear Friends,

I'm currently working on 68HC908LK24 and was having a question concerning the boot loader:

Freescale provided an application note about bootloader in HC08, in this application note we have two Tables for interrupt vectors, one at the protected segment of the flash and another at the non-protected segment.

I need someone with good understanding to explain to me how to use those two tables and how to make them point to my actual interrupt service routines in the programmed application via boot loader. Please help me as I'm really in a real mess here, Thanks

Hi!,
Freescale has developed a generic bootloader for all variants of HC908 and HCS08, the use of it does not require the user to modify their development, simply follow some simple steps.
Try this:
