Sandeep,

It depends on your use case. If you are using the interrupts in your secondary bootloader then you need to remap the vector table. You can find it in any example in C2000Ware which is using the interrupt. Please refer the same.

Hello Vivek,

Thanks for quick reply. I think in our project in secondary boot loader we are going to use interrupts.

i have gone through external_interrupt_cpu01 example code of F2807 in C2000 ware, but still confused about how to relocate vector table.

Is there any document or guidelines for doing this thing.

Sandeep,

You just need to populate the PIE vector table with the address of interrupt handler.

Following code in the example you are referring is doing the same.

Hope this is clear.
