[Rakesh Jagota]

Hi all,
I am using montavista linux priviewkit 2.4.17. Currently I am using nfs. How
can I create jffs2 file fyftem. I am working with IBM power pc 405. Can
anyone suggest me, how to create the jffs2 filesystem for PPC 405.

Thanks & Regards,

Create a directory  with  all  the  required  files  for  yout  JFFS2
filesystem,  and use the mkfs.jffs2 which comes with the MTD tools to
create a JFFS2 image.

See also the mkfs.jffs2 man page.

Best regards,

Wolfgang Denk

Hi all,
I have downloaded the source and I have installed it my host machine as per
the instruction. I am not able to compile it for jffs2, but its getting
compiled for jffs, using the following command:

In the Makefile I have chnaged the linux directory as per my target sourec
directory for IBM Power PC 405.

make jffs


After that I have complied the "util" using "make" command.
I am getting confused , to get the final image. I am using the following
command, can you pl tell em whether I am doing it right or wrong:

====================================================================
[root@Rakesh mtd]# ./mkfs.jffs -d /home/test/mtd/fs/jffs -o /tmp/jffs.image
====================================================================

and


====================================================================
[root@Rakesh mtd]# ./mkfs.jffs2 -d /home/test/mtd/fs/jffs -o /tmp/jffs.image1
====================================================================

With the first option I am getting the jffs.image of  1705432Kb and with the
second option , when I use mkfs.jffs2, I am getting the jffs.image1 of size
657876KB


Can anyone suggest me whether I am doing  it right or not. And can I use
anyone of the command like mkfs.jffs or mkfs.jffs2.


Thanks & Regards,

Rakesh

JFFS2 uses compression.
There is a paper in Red Hat's web site about JFFS/JFFS2 that you could read.
