se_sc (IVOR8) after jump from bootloader to user application

[bjrajendra]

Hello all,

I tried to implement the flash bootloader in my MPC5602P on CW2.9. I completely flashed user_application code from my bootloader, changed the vector table starting address and executed the jump instruction to address (user_application sector address+4). Immediately, after jump there is an se_sc instruction getting executed which leads to system call interrupt IVOR8. And I got stuck here. Not able to find what to do?

Kindly do the needful,

Regards,

Raju

Hi,

And do you want to call System call?

Then you must implement some handler into IVOR8 exception.

If not, then just remove se_sc instruction to avoid system call.
