Read only jffs2 filesystem

Iam using a 6 MTD partition structure wherein i have two jffs2
filesystems and when i boot up, it mounts the filesystem as readonly.Even if i reboot my board, i get the root filesystem to be mounted readonly.
I cannot write anything to the filesystem
What could be the problem??

Thanks in advance!

I think the default mount options are ro for mtd. To change this, , you can do 2 things:

1) On the Linux cmdline root=/dev/mtdblockN rw
2) From the prompt/init scripts: mount -oremount,rw -t jffs2 /dev/mtdblockN /

Or you may have set the partitions to be read only oin the MTD map you created. (Check the mask_flags)

Finally, depending on your FLASH chips, the chips may always powerup in the Locked state, mine do, and you will need to unlock them before writing. I do thins under u-boot but iy could also be done with the unlock mtd command.

Those are my suggestions.

Thanks
Brian
