From all the posts i read here in the list, there seems not to be any solution guaranteed. The tricky change to mkfs.jffs2 don't work for me. It seems to work for small files, but i still get error messages copying a 600KB file in the partition. If it's true that the minimal jffs2 block is 4KB + some bytes, of course the patch to mkfs.jffs2 can't work. Some one suggested the "virtual erase block" solution. I would like to try to implement it, if i have the time. In any case, for the common users, is there maybe another flash file system that can work with 4KiB erase size ? Many thanks, Regards Angelo Dureghello
