Thanxs! man
    But I m at very basic steps .I have some questions?
1> Is the kernel 2.6 comes with JFFS2 support ? And how do i enable/compile 
with JFFS2.
2> After that How will I partition MY flash so its JFFS2? Any tool ot 
specific method of that ?

plz provide methods/steps u have to do this
Thanxs!

is JFFS2 is worth using for NAND flash ?
or it supports only NOR?

I come to know that JFFS2 has some problems at mounting [ takes longer
time ] and occupies more RAM?
How much time does it take to mount 512 and 1 GB flash? How much RAM does it
require?

Thanxs!

I guess you may start from the JFFS3 docs available at
http://www.linux-mtd.infradead.org/tech/JFFS3design.pdf

It is quite old and we changed our minds about several things.

You may also read Szeged guys docs at
http://www.inf.u-szeged.hu/jffs2/jffs3.php

But the last plan is to base JFFS3 on top of UBI which is a new
promising piece of software. Look at

http://www.linux-mtd.infradead.org/doc/ubi.html
http://www.linux-mtd.infradead.org/faq/ubi.html

So, to put it differently, there is no cool and clean documentation.
There is some code and prototypes but they are far from something usable
yet. But if you are eager enough you withstand this :-)

Alternatively, there is a LogFS project, see
http://www.linux-mtd.infradead.org/doc/logfs.html

I do not follow it but there is some code exist. You may be interested.

Just try it. I know people using it with 512 MiB NANDs and are quite
happy.
