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.shCompile 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_installInstall 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

ReplyDeleteFantastic - for the 3.12 tips.
ReplyDeleteI've got a BBB to investigating the powerManagement. To do above had to get the compiler and angstrom-distribution.org/toolchains/ is down.
So used
sudo apt-get install gcc-arm-linux-gnueabi
which pulled in gcc-4.6
then on building had to modify
CROSS_COMPILE=arm-linux-gnueabi-
It compiled OK. So dumb question (I guess I should try it ..) but do you think its going to be OK to use or likely to brick the BBB?
