Actually, pushed this patch to l2-mtd.git: From: Artem Bityutskiy <artem.bityuts...@linux.intel.com> Date: Sun, 19 Aug 2012 22:22:23 +0300 Subject: [PATCH] arm: sam9_l9260_defconfig: correct CONFIG_MTD_UBI_BEB_LIMIT UBI has changed the MTD_UBI_BEB_LIMIT semantics. It used to be a percent of total amount of eraseblock in the partition, and now it is the maximum amount of bad eraseblocks on the entire devise per 1024 eraseblocks. So not only the units changed, but also the meaning. Richard Genoud <richard.gen...@gmail.com> says: "I found the board: https://www.olimex.com/dev/sam9-L9260.html and the nand datasheet: http://www.rockbox.org/wiki/pub/Main/LyrePrototype/K9xxG08UXM.pdf page 11, we can see that the max_bad_bebper1024 is 25 (100 for 4096)" Thus, use "25" for sam9.
