Recovering from Secure Boot on S32K3

[end48]

Hello,

I'm currently implementing secure boot on a S32K310. I've got two questions:

1. In case I configure secure boot on an SMR, how can I recover if the code in this SMR becomes corrupted? Do I need to flash with a debug probe the non corrupted firmware again? Is there another way?
2. In case I need to modify the code in the SMR after activating the secure boot (during development typically), can I disable secure boot before updating the code and reconfigure secure boot on the new code?

Thanks,

Benoit

1) You will have to update SMR if possible.

2) Once the secure boot is enabled, it can't be disabled.
