Subject: How to set up kernel 3.5.0 for Pandaboard ES

Hi there,

I kind of new to kernel building but I would like to try my own kernel. I
pretty much followed the "how to" on this site (
http://elinux.org/Panda_How_to_kernel_3_5_rcx ) to install the 3.5.0-rc7
everything is okay but I don't get why they I need some different files
(generating an MLO and an u-boot.img) for the Pandaboard ES (the older
board doesn't require these) and what should i do with these files?
How can I configure or install the MLO & u-boot.img

When I just preoceed with the normal "how to" I just get an
vmlinuz-3.5.0-rc7-omap4 and an initrd.img-3.5.0-rc7-omap4 which is enough
for the flash-kernel script.

Regards,

This link may help you to understand why you need MLO/uboot:

Thank you to pointing me to this tutorial. But I still not clear with the
Kernel installation.
Because now I have a MLO & a u-boot.img (which I should copy to the FAT
partition of the SD card)
Are these additional files to the compiled kernel from source or is this
standalone?

I'm just wondering because compiling the kernel from source takes almost an
hour compared to this solution, which takes 2 min

Hi there,

I used the tuorial from this site to build and install ne new kernel.
I copied the MLO u-boo.bin and the uImage to the FAT partition of my
Pandaboard and then I can boot but I get following message:

FATAL: Could not load /lib/modules/3.5.0-rc7-dirty/modules.dep: No such
file or directory
fsck from util-linux 2.20.1
/dev/mmcblk0p2: clean, 319456/3887104 files, 10158442/31093248 blocks
modprobe: FATAL: Could not load /lib/modules/3.5.0-rc7-dirty/modules.dep:
No such file or directory
modprobe: FATAL: Could not load /lib/modules/3.5.0-rc7-dirty/modules.dep:
No such file or directory

after the boot up I tried to load a module manually without success. This
is the result:
ls: cannot access /lib/modules/3.5.0-rc7-dirty: No such file or directory

would be great to get your help. I dont know where the failure is..

Regards,

sorry I forgot the link of the tutorial. (
http://elinux.org/Panda_How_to_kernel_3_5_rcx )

Basically I do.

Getting mainline Kernel

git clone http://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
cd linux
git checkout v3.5-rcx

Getting special uboot and MLO for Pandaboard ES

mkdir pandaboard-es
cd pandaboard-es
git clone git://git.linaro.org/boot/u-boot-linaro-stable.git
cd u-boot-linaro-stable
git checkout -b pandaboard-es origin/Linaro-u-boot-2011.12

Make my own config file ( copied the rc7 inside
http://elinux.org/images/1/14/Config.3.5-rc7.1)

vim .config

sudo make menuconfig

build the uImage

make ARCH=arm CROSS_COMPILE=Path_to_your/arm-2010q1/bin/arm-none-linux-gnueabi- uImage

then I copied everything to my FAT partition and booted
