don't know what the sector size is but for nvs this would need to be at least 3 sectors to be usable

sizes are very different? If using different sizes then the extra sector should be in slot 1 and swap using offset should be used rather than swap using move

Thank you for your feedback.
Before addressing the comments, if you could please provide some references on algorithm-based partition distribution or other useful resources, they would be very helpful.

48KB is the minimum MCUboot partition size, Flash sectors are atmost 4KB on this SoC, so why give more to MCUboot?
Same for other Flash-constrainted SoCs with sub-32KB sector size.

I just based it on how the nucleo_wba55cg was added, and also compared the sizes of the flash sectors/pages in the refman and adapted with the rest so that it worked on the tests.
If you have some references on the rules to follow, that would be welcome.
