INTC and IVOR_branch_table

[andrerm]

Hello everyone.
I'm working on MPC5777M. I have a problem with INTC management. When the PIT_CVAL reaches zero and sets the interrupt flag (TFLG0.TIF) register at 1, I jump to the IVOR_branc_table correctly(i think). Although the address is right I can not succeed in making the next jump for managing the IVOR4. It almost seems as if I lose control of the device.

I set the INTC_CPR2 to priority 0 and the register INTC_PSR [TFLG0] to 1 as read on some Application Notes, the IVOR_branch_table address is correct so I do not understand where the problem is.

Do you have any suggestions? Any example?

Hi,

This should be quite strait forward.

We have posted examples for what you are trying to achieve here on community:

Example MPC5777M PIT ISR GHS614 

And also bunch of other examples on main example repository:

https://community.nxp.com/docs/DOC-329623 

I suggest you to check the first one. If you will still struggle we can have a look at yours. But you have to share with us at least output file (bin, elf, s3, etc..)
