Bootloader int_global information

[niccolo.calandri]

I'm triying to modify the BOOTLOADER in order to update the firmware from an External EEPROM, for OTA.

I almost understand all the CCSC example except for this sentence:

It's the 'revectorer' (created word...).

The bootloader sits at the bottom of memory (it has to in order to be called on boot). Problem is that the interrupts call one or two locations immediately above this (one for a PIC16, two for a PIC18). The 'jump_to_isr()' instruction, is a special one, that automatically inserts the jump(s) (both if necessary), 'up' to where the boot code resides in your loaded program.

So it 'revectors' the one or two interrupt calls up to the loaded code. Does nothing else.
