Dear Ricardo and Wolfgang,
Very thanks for your kindly support.
I am sorry I made a mistake.
Before you mount /dev/mtdblock4, you have to use mke2fs to format it.
Now I think my MTD function is almost ready, except write.
When I run "dd if=/dev/mtd1 of=kernel.img", it's OK.
But when I run "dd if=kernel.img of=/dev/mtd1", it's failed. No error
message printed, and the process time is shortly, cause Bad CRC.
Thanks,
Johnson Cheng

Well, do you have an mtdblock4 entry in /dev?
Also, you should specify your filesystem type to mount, like in:
mount -t jffs2 /dev/mtdblock4 /mnt
BTW, -t jffs2 is just an example.
HTH,
