Hello,
while testing the MCUboot fork from NXP, I noticed that in the September preview release a useful feature has been removed.
Specifically, I am referring to the support for three-slot mode with Encrypted XIP (two staging slots + one execution slot, used to enable revert).
I saw this commit:
7c455cf2d
with the message:
[MCUX-80671] Encrypted XIP: remove customization for three slot mode
Could you please explain why this functionality was removed?
- Is it considered deprecated or no longer supported?
- Are there plans to reintroduce it, or should we adapt our designs to use only two slots in case of encrypted XIP?
- Was this related to technical limitations, or more to simplify the codebase?
This feature was quite valuable for our use case, and understanding the rationale behind its removal will help us plan the next steps.
Thank you in advance for your clarification.
best regards
Max
