This command will take a little while to download any extra bits it needs and format your card.

		+
		+	== Compiling your own Kernel (Advanced) ==
		+
		+	This is for advanced users who want more customizability with their kernel. You will need bootable MicroSD card created using linaro-media-create.
		+
		+	Install the cross toolchain to cross compile your kernel. Details to install on Ubuntu 10.04 and 10.10 can be found [https://wiki.linaro.org/Resources/ToolchainInstall-10 here] and for Ubuntu 11.04 and later can be found [https://wiki.linaro.org/Resources/ToolchainInstall-11 here]
		+
		+	Clone the source code for the kernel using git. A list of kernels can be found at http://git.linaro.org.
		+
		+	$ git clone git://git.linaro.org/kernel/linux-linaro-3.1.git
		+
		+	Next, select a defconfig file to use as the .config file. The .config file contains what modules we want built into our kernel. For the Overo, the omap2plus_defconfig works as a good base.
		+
		+	$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap2plus_defconfig
		+
		+	There's no point in building our own kernel if we are going to use default configs. To tweak the modules installed, run the following command. You will be greeted nice GUI to select your modules. Press 'Y' on the module if you want it to be built inside the kernel, 'M' build it as a module, and 'N' to exclude it.
		+
		+	$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- menuconfig
		+
		+	Now build the kernel and modules.
		+
		+	$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- uImage
		+	$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- modules
		+
		+	To deploy your custom kernel, mount your MicroSD card created using linaro-media-create. Find out where it mounts and run the following commands.
		+
		+	$ cp arch/arm/boot/uImage /media/boot/
		+
		+	For the modules, run the following:
		+
		+	$ make ARCH=arm INSTALL_MOD_PATH=/media/rootfs/ modules_install
		+	$ make ARCH=arm INSTALL_FW_PATH=/media/rootfs/lib/firmware/ firmware_install
		+
		+	On the target, pause the boot process and type in the following commands
		+
		+	setenv loadbootscript '' // This disables the UUID validation of the kernel/rootfs
		+	setenv console 'ttyO2,115200n8' // Depends on the console for your platform
		+	run bootcmd
		+
		+	To save these commands, use 'saveenv' before 'run bootcmd'
