The kernel source is maintained in the oswald-kernel git repository found at https://code.oregonstate.edu/git/oswald-kernel.
Notice that there are a number of branches on the main kernel tree:
- master - This is the main branch, use this for normal use
- oswald-dss2 - This branch keeps up to date with upstream video trees
- oswald-origin - This branch keeps up to date with upstream (kernel.org)
- oswald-goskab - This is Ben Goska's branch, be careful if you decide to use it as it is never considered stable
Checking out the code
The OSWALD kernel repository is maintained using git so it can be checked out using:
git clone git://code.oregonstate.edu/oswald-kernel
Configuring the kernel
To configure the kernel with the default settings for the OSWALD run the command:
Then, you can manually configure kernel options using your favorite method such as:
Building the kernel
In order to build the kernel, you must have a cross-compile toolchain for the OSWALD on your system. The easiest way to get one is get use the provided SDK. Otherwise, if you are familiar with Gentoo you can build the cross-compile toolchain using these instructions.
If you are using the toolchain provided with the SDK, you can execute the following command to build the kernel:
CROSS_COMPILE=arm-radix-linux-gnueabi- make -j2 uImage
If you are using a Gentoo cross-compile toolchain you will have to use the command:
CROSS_COMPILE=armv7a-unknown-linux-gnueabi- make -j2 uImage
Note that you should increase the "-j2" argument if you have a fast, multi-core system and want to speed up the compile time.
