Writing mtdblock

[Rahanesh]

Hi all,

I have four mtdblocks in my flash .
mtdblock0 -> Primary bootloader
mtdblock1 -> uboot
mtdblock2 -> JFFS
mtdbloack3-> config

During Linux booting , it mounts mtdblock2 to a temp folder which can be 
seen as a part of ramdisk(root file system of linux)

Now from Linux i need to flash a new jffs image to mtdblock2 itself. 
Is it possible?  How can we do this?


 
Please help me on this. I am very new to Linux


Thanks
Rahanesh
