Hi,

Is there anyone enables FIH when developing or releasing?

Background:

We got a couple of HAL updates during feature development and found FIH affects the development progress much, as we need to provide two sets of prototypes and implementation for involved functions, this doubles the efforts on debugging or coding.

So a draft idea in my mind is to shut down part of the functionalities during this update stage and recover them back if FIH still can prove its importance later.

These functionalities are KEPT during the update stage:

- FIH delay, which makes it harder to find the exact time point.

- Protection unit validation, ensures the protection unit is initialized as expected.

Please provide your feedback about the usage and the idea. For platforms that are applying this feature, we need to find out a trade-off way.

Thanks.
