This error means that you are trying to mount too small UBI volume. -Probably because you flash is too small? Try to use JFFS2 then, becasue it +Probably because your flash is too small?

Indeed, UBIFS stores much more indexing information on the flash media than JFFS2, so it has much higher overhead. Also, UBI has some overhead (see -- 1.7.1
