Program crashes to Dummy_Handler (IPSR = 6,3) from code that worked fine with a demo board.
Have my own board that I'm bringing up: ATSAMS70J21B. Code was developed on SAM E70 Xplained board (ATSAME70Q21) and worked fine.
Crash occurs in a library function (library developed in-house). Other than the IPSR code, there appears to be no reason for the crash, it happens right at the function header.
Funny thing is that changing optimization levels affects where the crash occurs.
Only 15% program and 7% data memory used.
