We fixed few bugs in UBIFS and mkfs.ubifs so we recommend to update. However, beware that we changed media format so the old UBIFS images won't mount. The latest UBIFS version is 0.6. 2. We've implemented a new user-space tool "ubiformat" which was our response to this http://lists.infradead.org/pipermail/linux-mtd/2008-April/021203.html post where one of our users constantly used "flash_eraseall" and wiped out the erase counters all the time, so she probably worn out some eraseblocks. Or at least some eraseblocks are now much more used than the others. Please, use this utility instead of "nandwrite" and "flash_eraseall". Please, glance at: http://www.linux-mtd.infradead.org/faq/ubi.html#L_ubierase http://www.linux-mtd.infradead.org/faq/ubi.html#L_flash_img 3. The UBI web-page now contains some hints for the people who are going to add some UBI support to their flashing programs: http://www.linux-mtd.infradead.org/doc/ubi.html#L_format Also, we've got one user who tried UBIFS on his NOR flash, and after some minor bug-fixes it worked. Regards, Adrian, Artem.
