1> eraseall /dev/mtd1
2> cp test.img /dev/mtdblock1 
     (should i use "nandwrite" instead of "cp" here?)
3> mount -t jffs2 /dev/mtdblock1 /mnt

   dear all,
   thanks for your help,

  now i try to:

 1> eraseall /dev/mtd1
 2> cp test.img /dev/mtdblock1

      test.img is created from:
     mkfs.jffs2 -r rootfs_jffs2 -e 16K -l -o test.img
     nand device is TC58128FT (16MBytes Nand flash)
      (should i use "nandwrite" instead of "cp" here?)

 3> mount -t jffs2 /dev/mtdblock1 /mnt

  then it still report many "magic bitmask not found"
   do i missing something?
   or is it caused by bad-block/ecc-error?

   thanks in advanced!:)

   best regards,
   kevin
