Set of example kernel-modules for the Raspberry Pi (includes basic module sample as well as samples for GPIOs, GPIO-interrupts)
To compile the module examples, a cross-compiler for the Pi is needed:
$ git clone http://github.com/raspberrypi/tools $ su -c 'cp -r tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/ /opt/'
Also make sure, to adjust the path to your cross-compiler in setenv.sh.
In the top-level directory first make sure your cross-compile environment is set propperly in setenv.sh.
Then source it by issuing:
$ source ./setenv.sh
Now, build everything with
$ make
This may take some time, since it downloads the Pi kernel sources, and also compiles them (otherwise you will not be able to produce any modules).
The resulting modules (the examples and the default modules) could then be found under sysroot. For easier
transfer to the Pi, also an archive rpi-modtest-sysroot.tar.bz2 is provided. For transfering the modules
to the Pi, again see this [page] (http://elinux.org/RPi_Kernel_Compilation).
