How to compress the filesystem

How to compress the filesystem

[naga rajan]

Hi all,

         I followed the steps in* osk newbie guide & osk4 dummies *and
generated my own filesystem. It comes around 28MB with specific library
files required for my sample application. The factory filesystem image is
around 14MB and it consists of all the library files in the /lib.I like to
know how to compress my own filesystem to the factory filesystem
level.Isthere any parameter has to be included with
*mkfs.jffs2 *filesystem creation process?
Please help me in this regard.

Thanks in advance,
B.Nagarajan,
SANDS

I don't know about the OSK supplied filesystem. But you may like to use
"arm-linux-strip" tool on the libraries.

	JFFS2 already compresses, and quite extensively.  Your problem seems to
be that you have too many libraries: you almost certainly do not need
every library out there.  My /lib/ is 4.9MB, and this includes kernel
modules (my toolchain's lib/ is around 31MB, so you can see that most of
the libraries are not being used).  If you remove all the unused
libraries, you will likely cut things down considerably.  The OSK Newbie
Guide talks about this in the Filesystem chapter.
