Does it mean that UBI volumes are not in > /proc/partitions? Yeah, the thing is that neither UBI volumes nor MTD devices are in /proc/partitions, just because they are not block devices and they are not members of the blkock device infrastructure. They form a completely separate subsystem. Here are some more data: http://www.linux-mtd.infradead.org/faq/general.html#L_mtd_what http://www.linux-mtd.infradead.org/doc/ubifs.html#L_raw_vs_ftl There are already 3 FSes which work with MTD: JFFS2, UBIFS and (out-of-tree)YAFFS2. -- Best Regards, Artem Bityutskiy (Артём Битюцкий)
