Ooppps ... you are right...  

> cat /proc/mounts /proc/filesystems

/mnt # cat /proc/mounts 
/dev/root / ext2 rw 0 0
/proc /proc proc rw 0 0
/dev/mtdblock0 /mnt usbdevfs rw 0 0

/mnt # cat /proc/filesystems 
nodev   sockfs
nodev   shm
nodev   pipefs
nodev   proc
        ext2
nodev   usbdevfs
nodev   devpts
        jffs

but where is the flash ?
Is the major and minor number are correct which I have specified in 
previous mail? (for the reference mtd0 90 0, mtdr 90 1, mtdblock0 31 0)
In the /proc/mtd it shows the mtd0, mtd1 and mtd2 entries.
And when i give the command

mount -t jffs /dev/mtdblock0 /mnt/
mount: Mounting /dev/mtdblock0 on /mnt failed: Permission denied

how do I mount the jffs??
