Looks like a problem with the underlying flash drivers, not with JFFS2.
Double-check that the partition really is empty when you've attempted to
erase it, and that anything you write to it via pwrite() to /dev/mtd2
actually works.
Check bus width, Vpp handling, etc. are correct. If it's the newer flash
which requires unlocking after every reset, check that's done too.
