hi..
I m using custom board same as MPC8272ADS board,
linux is montavista 2.6.10 boot loader is u-boot-1.1.2.
I m getting jffs2 mounting on PQ2FADS-ZU board.

Through nfs mounting of root file system.I m trying jffs2 mounting without any image( with empty patition).. it is giving 100% of space is used.I m getting same output with jffs2 image also.
what is the actual problem?

Here is the output...

14000000
root@cashel:/# cat /proc/mtd

The actual problem is that your don't read error messages.

                                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^

Your file system / partition is read-only, probably because the flash sectors are locked.

Try unlocking the flash partition before using it.
