Hello, I have a TMS570LS1227 development kit. I want to create a "POR" interrupt when I press the "PORRST" button in the dev kit. I couldn't find any documentation on this, how can I do this?

    Pressing the nPORRST button will generate a cold reset rather than a interrupt.

    An interrupt is caused by an external event. When an interrupt occurs, the CPU will store the state of the running code into the stack and jump to a vector or address. A POR reset has nothing to do with code, it causes CPU to restart the program execution at the entry point. The POR reset doesn't save the state of the running code.
