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
