Hi all,

i just wanted to know if there is any utility to see how the JFFS2
filesystem is written on the flash. Places where inode structures are
stored when a new file is created or if a file has been modified where
actually on the flash this part is written is a new inode created or the
same inode is re-written to some another location along with the data
node.

i tried to view the flash layout using the "mtd-debug read" utility and i
can view part of the data nodes but i am not able to view what exactly is
written as the metadata of the file. Is there any way of getting the
information of the metadata stored on the flash. 

thanks in advance

Not sure if jffs2dump can meet your requirement......
It can dump the meta data of each node on the flash.
