Kernel not working
Hello,
I'm a newbie, so please forgive me if this has been answered elsewhere.
I have the 2.6.8rc3 kernel source downloaded from linux.omap.com and have built with GCC 3.3.2. I have not done any tweaking in make xconfig, so it should be the standard OMAP 5912 OSK kernel. I get the vmlinux output which I put through objcopy and the appropriate mkimage for my version of Uboot (1.1.1) to provide me with an image which I tftpboot onto the board.
The system gets as far as uncompressing the kernel and then I get the message:
Starting kernel .
And nothing else happens.
Can anybody tell me it went wrong and what I can do to try and get it working please?
I'm sorry if I haven't provided all of the right information for you to help but I'm not sure what I should be providing at this point. If you can let me know.?
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.

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.

As I am not a OSK user, but I remember someone saying that updating the u-boot helps on OSK. Please try the latest version of u-boot then.

Hello again,
Please accept my apologies if I seem a little slow. I downloaded the pre-built 3.4.2 toolchain and it has the bug mentioned in the newbie guide so that Uboot 1.1.3 does not build. Since, I do not have the source to the 3.4.2 toolchain it is impossible for me to apply the patch recommended by the documentation to elf32-arm.h ;-(
Can somebody point me at a pre built arm-linux tool chain so I can build Uboot 1.1.3 please? Or a pre-built Uboot.bin 1.1.3 for OMAP 5912OSK?
Many thanks,
Richard.

Your problem sounds like the one caused by the bug in the old version
of u-boot. I believe the u-boot binary at the CE Linux wiki is good, so you may like to try it out from here:
