Hi Christopher,

It’s possible that a stack overflowed. Kinetis platforms have a “system MPU” instead of the Arm MPU, and memory access violations trigger a bus fault.

That's interesting, because now that I think about it, I did have to disable the MPU to even get to main(). Good catch!

Do you know if Zephyr has a way to instrument stack usage?
