[ABANDONED] IAR J-Link SAMA5D2 Undefined Instruction Exception

40490FDB · May 18, 2018 at 6:00 PM

Using IAR IDE and a J-Link Base ICE with SAMA5D2 on XPlained eval board. Stepping through the code, the IDE locks up. When I break, the code is execting the Undefined Insruction exception handler. Looking at the LR, the instruction at that address disassembles, so I presume it is not the problem. Stack pointer looks good.
Any suggestion how to diagnose this condition?

Maybe it is a valid instruction, but maybe not for the active processor mode: privilege; thumb/arm mode..
