Make sure to set fm_autoconvert: http://www.linux-mtd.infradead.org/doc/ubi.html#L_fastmap If set, UBI create after a few writes a fastmap. Speaking of other techniques, you can improve scanning time also by tuning UBI for your NAND controller/setup. E.g. transferring only the amount of bytes needed for an header. Or reading without ECC and re-reading with ECC if the header CRC-check fails. Thanks, //richard
