Thanks for your replies and sorry for my delay in re-replying.

I understand what you mean and, as we were afraid of, we will have to “translate” like our file to cope with the changed address lines, and then the most difficult part for us: to test it in our boards already made (as the memory we are using is a BGA type…)

Anyway, it would we a lot easier if we find another memory part for the future having “direct” addressing mode rather than this fiddly one
