RE: Kernel not working

["Richard Copeman" <richard.copeman@lauterbach.co.uk>]

Hi,

Many thanks for the pointers. I have taken a look at the newbie guide. I
have got a 2.6.13.4 kernel built with gcc 3.4.1 as per the instructions in
the guide. I have the kernel image tftpboot loaded onto my OSK board and
things progress a little further (but not much).

I get:

Starting kernel ...

Uncompressing Linux......................................................

And then it all stops. In the newbie guide there was a section about this
and I have added the extra head-omap.o to my Makefile in
arch/arm/boot/compressed and rebuilt but still no improvement. Grepping
through the build logs the object has been included so I'm guessing my mods
worked ;-)

On another point, my board does not allow me to save my Uboot environment.
Typing save gives me:

Saving E"@ironment to Flash...
Un-Protected 1 sectors
Erasing Flash...Can't erase unknown flash type 00000000 - aborted
Erased 1 sectors
Error: start and/or end address not on sector boundary
OMAP5912OSK#

This board is set at factory configuration and has not had Uboot updated
since I unpacked it. Is it likely that my board is not functioning
correctly?

Thanks,

Richard.

I don't know if you need to update u-boot or not, but you can update
the kernel from 

http://source.mvista.com/git/gitweb.cgi?p=linux-omap-2.6.git;a=log;t=7

A README for fetching the kernel tree is provided on 
http://www.muru.com/linux/omap/

You then please enable low-level debugging CONFIG_DEBUG_LL in the
kernel configuration and post the serial-output messages if any.
