sorry to bother u all. Actually i was assigning wrong minor numbers.
I got the mtdblock2 mounted using jffs2. But still jffs is not working :(
/dev # mount -t jffs /dev/mtdblock2 /mnt
jffs_scan_falsh():Free size accounting screwed
jfffs_scan_flash():free_chunk_size1 == 0x758c0, free_chunk_size2 == 0x0, fmc->free_size == 0x113540
JFFS: Failed to mount device 1f:02.
mount: Mounting /dev/mtdblock2 on /mnt failed: Invalid argument
Is jffs2 stable enough to use in production use or should i stick with jffs?
If i have to use jffs please guide me in this regard.
