Over the last few weeks, my mentors and I worked on the algorithm to be implemented for erase function selection, and it's finally complete. Please look at this
the depicted strategy looks quite good, IMO :) I originally thought we could solve the problem without a global view (building the list of everything that needs to be erased). But having read your flow chart, I believe it's a very good solution.
I have two remarks on the selection of later erase functions, i.e. the step
Are more than half the subsectors within the current sector also marked
You already mentioned at the beginning that we might have a problem if the region is not erase-block aligned. If this is the case, we should choose the smallest erase block to minimize the risk to hit any read/ write protection, e.g. check
region start <= current sector start && current sector end <= region end
If not, skip the sector for the current erase function.
And because we have to deal with a non-homogeneous sector selection (marked subsectors of different sizes) eventually, we shouldn't count "subsectors" but bytes, I guess.
And many thanks for drawing the picture! its quite helpful. We should definitely keep a final version in the documentation.
