Hello,

We are flashing our software using debugger Lauterbach or custom flashing tool. In both cases after flashing (sometimes) we got a trap 7 for NMI.
We have to execute a reset after that.
Do you have any idea why we get a Trap class 7?
Thanks!

The most likely cause is a watchdog timeout.

Have you checked the value of TRAPSTAT after the NMI occurs?

If TRAPSTAT.SMUT is set, what are the SMU alarm register values (SMU_AG0...SMU_AG6)?
