We are now moved to vger.kernel.org based OMAP list, so removing old
list. Your kernel version looks very old. Could you please try the
kernel from OMAP GIT. You can find instructions at
http://www.muru.com/linux/omap. GIT tree is at

http://source.mvista.com/git and also at http://www.kernel.org/git.

If you are trying to use the 2.6.8 kernel with the default file-system
that comes with the OSK, I don't believe this will work. The montavista
kernel that comes with the OSK is a 2.4 kernel and not 2.6. Therefore,
you should create a new flash file-system for the 2.6.8 kernel. 

Check out the OSK wiki page: http://elinux.org/OSK

In particular see the "OSK5912 Newbie Guide" that provides details on
how to create a flash file-system. 

http://www.capgo.com/Resources/SoftwareDev/osk-newbie-guide.pdf

Also, please copy the list. You can also search the mailing list on the
following page, as there has been a lot of discussion with regard to the
OSK in the past.

Cheers
Jon

You can download a rootfs and a 2.6.23 based kernel from:

http://www.angstrom-distribution.org/releases/2007.12/images/omap5912osk/

Let me know of they work for you.

Hi Rajagopal Venkat,

I´m using GIT´s Kernel, but I think it works the same. I´ve tryed to
follow TI´s instructions but it doesn´t help me very well.

I think you must configure your u-boot´s variables related with file
system. Send your your u-boot config.

regards

Fabiano
