s32g3 - unused exceptions/interrupts?

[RandyKrakora]

Customer is Ford.

The are trying to define default handlers for all their unused exceptions and interrupts on each core. Wondering if we have ever seen or recommended something like this?

And whether there is anything specific they should be aware of regarding this?

HI Randy,

I have seen both approach at customer Ignore or Reset.

Reset argument: because interrupt handler is not activated if we end-up in the interrupt handler something really wrong must of happen, therefore as we can't know the cause we Reset.

Ignore argument: this interrupt/exception is not relevant.

I would recommend Reset, it should not reduce system level availability as by design you should not go into this interrupt handler.
