kernel compiling

So by now there are real limitations to the demo kernel's available and I have been really wanting to enable some of the missing features as well as disable things I don't need.



EDIT:  The below links are broken. go here instead:

The best and most recent tutorial I've found on compiling the kernel is http://wiki.replicape.com/index.php?title=Compile_kernel_3.12 see also http://wiki.replicape.com/index.php?title=Compiling_the_kernel I'll copy his stuff to here just in case it gets deleted.

 Get and patch the kernel:
 git clone https://github.com/beagleboard/kernel.git 3.12
 cd 3.12
 git checkout origin/3.12 -b 3.12
 ./patch.sh

Compile the kernel:
 cd kernel
 cp ../configs/beaglebone .config
 make ARCH=arm CROSS_COMPILE=arm-angstrom-linux-gnueabi- LOADADDR=0x80008000 uImage dtbs
 make ARCH=arm CROSS_COMPILE=arm-angstrom-linux-gnueabi- modules
 mkdir rootfs
 make ARCH=arm CROSS_COMPILE=arm-angstrom-linux-gnueabi- INSTALL_MOD_PATH=./rootfs modules_install

Install the kernel on your BeagleBone:
 scp arch/arm/boot/uImage root@192.168.7.2:/boot/uImage-3.12.0
 scp arch/arm/boot/dts/am335x-bone*.dtb root@192.168.7.2:/boot/
 rm rootfs/lib/modules/3.12*/build
 rm rootfs/lib/modules/3.12*/source
 scp -r rootfs/lib/modules/3.12* root@192.168.7.2:/lib/modules/

Log in, move link, sync and reboot:
 ssh root@192.168.7.2
 cd /boot/
 rm uImage
 ln -s uImage-3.12.0 uImage
 sync
 reboot
