how to change the section message in s32ds from another project?

[vegetarian1]

Hello,

I create a project in s32ds. I find a file named "vector.c" and assembly language code in it. I make breakpoint in it, but can not be hit. When would these code be called? How to change it with another  function?(e.g. user application change these message in the bootloader)

Thanks for your attention!

I am a novice at S32DS.

The assembly code in vector.c would be invoked in a function named "xcptn_xmpl". It initializes core IVPR. The breakpoint in it can't be hit for assembly code, I don't know why.
