This is just a set of scripts to rebuild a known working kernel for ARM devices. This git repo contains just scripts/patches to build a specific kernel for some ARM devices.

Please send bug reports to "[email protected]".

1. GCC/ARM cross toolchain
2. Linaro

A cross compiler and the kernel source will be downloaded when you run any of the build scripts. By default this script will clone the linux-stable tree to ./ignore/linux-src with full history.

If you've already cloned torvalds tree and would like to save some hard drive space, just modify the LINUX_GIT variable in system.sh to point to your current git clone directory.

For users building the linux-stable tree with full history, at least 1GB of memory should be available for git(1) to clone the repository. If this is a problem for your build system, you can use a swap file to add more memory to your system.

To create a swap file on disk, you can run the following commands as a privileged user.

dd if=/dev/zero of=/swapfile bs=1024 count=1024k
mkswap /swapfile
swapon /swapfile

The preferred way of building the Linux kernel et al. is to build the Debian package. This has a number of advantages, including the ability to build the package on a host other than the one you install it on.

To build a Debian package one can use the following command.

./build_deb.sh

Optionally, to build the kernel image as a tar achive, use the following command.

./build_kernel.sh

To install a Debian package, use the following commands.

dpkg -i <deb>

To install the kernel image to an SD card (requires MMC variable set in ./system.sh) use the following.

./tools/install_kernel.sh

To install the kernel image to the local system use the following. Note, the kernel must've been built on the ARM board for this command to work.

./tools/local_install.sh

For development, one must first run ./build_kernel.sh, then use the files inside of the KERNEL directory for your local kernel development. To rebuild the kernel with local modifications, use the ./tools/rebuild.sh script.
