New page

=== Introduction ===

For the second day of this course we will actually be building our own kernel
and work on writing our first own driver. This builds on top of the
[[KernelDriverProgrammingCourse2015/Preparations | preparations]] and
[[KernelDriverProgrammingCourse2015/OutlineDay1 | activitiers] from the
first course day.

=== Preparation ===

If you've not done so already first walk through the [[KernelDriverProgrammingCourse2015/Preparations | preparations from day 1].

Since building a kernel from scratch can take a long time, it is a good idea to build the kernel beforehand:

1) cd into the linux directory:

cd linux

1) Update your kernel tree to my latest sunxi-wip branch

git remote update
git checkout -B sunxi-wip jwrdegoede/sunxi-wip

2) Make sure that you've the latest kernel configuration:

wget https://fedorapeople.org/~jwrdegoede/kernel-driver-programming/kernel-config
mv kernel-config .config

3) And build the kernel

make -j4 ARCH=arm CROSS_COMPILE=arm-linux-gnu- oldconfig
make -j4 ARCH=arm CROSS_COMPILE=arm-linux-gnu- zImage dtbs

This will take a while, once this is done (assuming there are no errors), you are
all set for the second day of the course.
