Overview
Linux kernel for CM-X300 modules provides support for on-board peripherals. Current support coverage is specified at O/S support coverage map page. CompuLab provides ready-to-run binary kernel images, and source code of the modifications and additions made to the Linux kernel to work properly with CM-X300 modules.
Building Linux kernel for CM-X300
mkdir /home/development/cm-x300/kernel
cd /home/development/cm-x300/kernel
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.26.tar.bz2
tar xjf linux-2.6.26.tar.bz2
cd linux-2.6.26
cat /path/to/x300-linux/kernel/linux-2.6.26-cm-x300.patch | patch -p1
export ARCH=arm
export CROSS_COMPILE=arm-linux-
make cm_x300_defconfig
make menuconfig
make && make uImage \
INSTALL_MOD_PATH=/home/development/cm-x300/rootfs make modules_install
In the above example, the Linux kernel image (uImage) will be created in /home/development/cm-x300/kernel/linux-2.6.26/arch/arm/boot, and the loadable kernel modules will be installed into the /home/development/cm-x300/rootfs/lib/modules directory.
Now, if you boot CM-X300 with newly created kernel image and with networked root filesysem at /home/development/cm-x300/rootfs/ the system will be able to properly load kernel modules and you avoid modules versioning problems.
