This one is already solved. Please refer below discussion and its previous thread on why NAND_NO_SUBPAGE_WRITE should _not_ be set, because it breaks compatibility with older UBIFS images. http://lists.infradead.org/pipermail/linux-mtd/2014-April/053262.html Also below is the appropriate fix without breaking backward compatibility. http://lists.infradead.org/pipermail/linux-mtd/2014-May/053745.html with regards, pekon -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
