In TC27x controller After increasing the interrupt priority bootloader is going to trap. what is the register setting after increasing interrupt priority and what is the connection between increasing interrupt priority and trap?

Hi,

Could you provide more details?
1. Which interrupt's priority is updated, leading to this? Could you share the interrupt configuration?
2. Could you share the working code snippet and the modified code snippet and what registers are changed?
3. You can refer to the example CPU_Trap_Recognition_1_KIT_TC275_LK-TR in ADS to understand the Trap class, Trap number, and how to identify the source of the trap.
4. You can refer to the call stack to find the instruction/access leading to the trap.

Best Regards.
