xdc.runtime.Error.raise: terminating execution

If I set a break point on 0x80015254

That gets me to line 1026 in Hwi.c

Which is in Hwi_dispatchIRQC

This is the line.

oldTaskSP = Hwi_switchToIsrStack();

The BIOS_start(); is the first real executable line in my main.c after initializing some local variables.

What am a missing here? I used this product many years ago and with the GUI and settings somethings became hidden or I just not remembering.
