Hi all,
I'm just starting looking into JFFS2 & MTD, after following the HOWTO,
mounting JFFS2 gives the following complain:

# mount -t jffs2 /dev/mtdblock3 /mnt
mount: Mounting /dev/mtdblock3 on /mnt failed: No such device or address

Hope somebody can hints me what am I missing.
Thanks in advance.

More info:

cat /proc/mtd gives:
dev:    size   erasesize  name
mtd0: 00020000 00020000 "bootp"
mtd1: 00080000 00020000 "zImage"
mtd2: 000a0000 00020000 "initrd"
mtd3: 00020000 00020000 "part1"

mtd3 is a jffs2  file system image created by mkfs.jffs2

ls /dev/mtd* gives:
