I tried it several ways and sometimes it worked and sometimes it does not. First I tried creating a filesystem using mkfs.jffs2 using argument -n --pad --little-endian --eraseblock=0x20000 and then write it to a nand partition using nandwrite -p /dev/mtd2 root.jffs2. Then I mount using -t jffs2 /dev/mtdblock2 /mnt/root. This never worked and sometimes I get an uncorrectable error <3> and sometimes I get the errors below. I also tried using another method where I first erase using flash_eraseall -j /dev/mtd2 then uncompress the root unto the partition (using tar -xz -C /mnt/root ). This worked sometimes and on the board that works it works and but I also notice that the board it worked on did not have any bad blocks in that partition. It may also worked on others that have bad blocks in one or two places. However, on other boards I get the same uncorrectable error repeating. Does anyone have any ideas? I would really appreciate the help. I'm on a sam9263 platform using 2.6.28.4 kernel and mtd-utils 1-1-0 and I also tried 1.2.0.
