I'm running OMAP-L138 on the LogicPD evaluation board. I try to use a portion of NOR flash for a flash file system. The /dev/mtdX interface seems to work well. I'm able to write and read data and from the flash. Also I've run mtd_tests (http://www.linux-mtd.infradead.org/doc/general.html#L_mtd_tests) succesfully (speedtest, readtest and stresstest). However, when I try use a flash file system (JFFS2 or UBI) I end up with a corrupted filesystem or UBI won't attach. The problems occur when I use linux davinci kernel 3.10. At least jffs2 works when I use 3.3. kernel (TI PSP kernel without TI patches). So the problem seems to be related to the kernel version. Please, any ideas what could be the cause of my problems? Here's a log of what I try to do:
