CCS/TMS320C6457: C6457 DSP / BIOS Interrupt Sequence Related

SKANO URI
Prodigy 30 points

Part Number: TMS320C6457

Tool/software: Code Composer Studio

Hello, 

I use the C6457 chip in the project I'm working on.
I am having trouble with the on-chip BIOS and I am looking for help.

I can change the HWI in the DSP / BIOS Config, and I know that these are prioritized in order.
1. I wonder if it is possible to change the priority of these users as they like.
2. And I wonder how to change it.
3. If it is supposed to be HWI_RESERVED0 OR 1, it is possible to make HWI_INT4 ~ 15 higher priority.

I am currently using CCS 3.3.

Thanks, I Waiting your Help

    The interrupts on the C6x are remappable.  You don't need to change the priority of Hwi14 or Hwi15.  You could just remap your interrupt to a different Hwi.

    The only time the priority is taken into account is if more than 1 interrupt is pending at the same time.  You cannot map into reserve interrupts.  Only Hwi 4-15 are re-mappable.
