Hi Senlent,
Thanks for Providing the Reference code, but the issue is still not solved.
Please take a look at the code which we are using.
Application Linker File:

Bootloader Linker File:

The Jump to application code used is as per the s32k312 code.

When i run in Debug mode it is going to Default handler in the bootloader code.
If i add VTOR relocation SCB->VTOR = (0x0044A200 ); then it is not going to default handler, but still Jump to application is not happening.
I have used the offset as per s32k312. Can you please let me know if the offset for s32k311 is different as i am not able to get the information.

Thanks
Kiran
