Links used in video
Linux Kernel Source at Github
https://github.com/beagleboard/linux
Getting Kernel from github
git clone git://github.com/beagleboard/linux.git
Dependencies
Install lzop ( file compression software)
$ sudo apt-get install lzop
Install compiler gcc compiler for Linux “gcc-arm-linux-gnueabihf”
$ sudo apt-get install gcc-arm-linux-gnueabihf
Steps to building Linux Kernel
$ make j4 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf mrproper
(clear all previous kernel compilation configuration and files left from previous build)
$ make -j4 ARCH=arm bb.org_defconfig
(Generate .config file)
$ make j4 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf zImage
(Building kernel to generate zImage)
$ make j4 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf modules
(Building kernel to generate Kernel Modules)
$ make j4 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf dtbs
(Building device tree)
