You may need to build your kernel (for example, to enable the required modules). To build a kernel for the Wiren Board, you need to use a special repository that contains a kernel adapted for the Wiren Board. | |||
'''0.''' | '''0.''' The kernel should be built on your Linux desktop (not on the Wiren Board - theoretically it is possible, but it will require several gigabytes of free space, and will take a long time). | ||
Make sure you have git installed(http://en.wikipedia.org/wiki/Git_%28software%29). If not, install it:<pre> | |||
sudo apt-get install git | sudo apt-get install git | ||
</pre> | </pre> | ||
Select a random user name and email: | |||
<pre> | <pre> | ||
git config --global user.name "Imya Familiya" | git config --global user.name "Imya Familiya" | ||

'''1.''' | '''1.''' Download a set of scripts that makes it easy to build: | ||
<pre> | <pre> | ||
git clone git://github.com/contactless/build_kernel.git | git clone git://github.com/contactless/build_kernel.git | ||
cd build_kernel | cd build_kernel | ||
</pre> | </pre> | ||
'''2.''' | '''2.''' Clone and initialize the Linux repository. | ||
You can clone repository via https (if you have no account on github.com): | |||
<pre> | <pre> | ||
git clone https://github.com/contactless/linux KERNEL | git clone https://github.com/contactless/linux KERNEL | ||
</pre> | </pre> | ||
or via ssh if you have an account: | |||
