__FORCETOC__
<section begin=Body/>
''{{{kit-repo}}}'' provides one (or more) pre-built root file system, that can be used during the evaluation/development/deployment cycle. For instance, the root file system included in the <code>{{{kit-repo}}}-image-devel</code> image is suited for the development phase, since it provides a relatively rich set of packages including tools and libraries used to debug the application code. The pre-built root file systems are located here: <code>/home/dvdk/<target_name>/rfs/<kit_name></code>.
Besides the pre-built root file systems, DAVE also provides a rich repository containing pre-built applications and libraries. These packages can be easily installed on the target by using the <code>smartapt-get</code> tool. Please refer to [[Advanced_use_of_Yocto_build_system_(''{{{kitDESK-MX8M-AN-repo}}}'')#Using_pre0001:_Package_Management_with_apt-built_package_archiveget |this sectionapplication note]] for more details.
To generate the supported root file systems, the build of the Yocto BSP has to be run. The output of this process is an image containing the U-Boot binary file, the Linux kernel image, and the selected root file system image. The following sections describe in detail how to execute this operation.
{{ImportantMessage|text=The following procedure requires the access to the DAVE Embedded Systems' git repositories. The access to such repositories is granted to development kit's owners only. Please refer to [[Accessing_DAVE_Embedded_Systems_restricted_git_repositories|this page]] for detailed instructions on how to get it.}}

==== Initialize the build environment ====
Check that the following packages are install:
Before running the build, the environment must be initialized properly.
''{{{kit-repo}}}'' Yocto BSP uses [https://code.google.com/p/git-repo/ git-repo] tool to fetch all the required git repositories. To install it, please use the following commands:
<pre class="workstation-terminal">
dvdk@vagrant:~$ mkdir -p ~/desk-mx-l/yocto
dvdk@vagrant:~$ cd ~/desk-mx-l/yocto
dvdk@vagrant:~/desk-mx-l/yocto$ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo-1 > repo

dvdk@vagrant:~/desk-mx-l/yocto$ chmod a+x repo
</pre>
then, fetch the Yocto repositories with the proper branch:
