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>apt-get</code> tool. Please refer to [[DESK-MX8MX8M-AN-0001:_Package_Management_with_apt-get | this application note]] for more details.

===How to build the Yocto BSP images including the U-Boot binary file, the Linux kernel image, and the target root file system imagewith KAS===

Before running Check that the build, the environment must be initialized properly. [[DESK-MX8M-L | DESK-MX8M-L]] Yocto BSP uses [https://code.google.com/p/git-repo/ git-repo] tool to fetch all the required git repositories. To following packages are install it, please use the following commands:

dvdk@vagrant:~$ mkdir sudo apt-p ~/deskget update && sudo apt install gawk wget git diffstat unzip texinfo gcc build-mxessential chrpath socat cpio python3 python3-l/yoctodvdk@vagrant:~$ cd ~/deskpip python3-mxpexpect xz-l/yoctodvdk@vagrant:~/deskutils debianutils iputils-mxping python3-l/yocto$ curl http://commondatastorage.googleapis.com/gitpython3-repo-downloads/repo-1 > repo % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed100 29945 100 29945 0 0 64816 0 --:--:-- --:--:-- --:jinja2 libegl1-mesa libsdl1.2-:dev pylint3 xterm python3-subunit mesa- 64676dvdk@vagrant:~/deskcommon-mxdev zstd liblz4-l/yocto$ chmod a+x repotool

==== Running the build ==== Please note that even the basic root file system requires a few hours to build on a possible solution mid/hi range desktop (4-6 cores, 8-12 GiB RAM) also depending on your Internet connection speed (all sources are fetched from the network). Nearly 20GiB of disk space is required for the build. The process may be slowed down significantly since the performances of a virtual machine are reduced if compared to the physical hardware. Thus, it's recommended to disable check the hardware capabilities of the host system and, when building with Yocto is required, to consider the following options: * Migrating the build system to a physical machine* Assuming that the host system has the required resources, extending the hardware capabilities of the default MVM (e.g. adding more cores and disk space). Once completed the initialization phase, developers can launch the Yocto image build with KAS, with the SSL verification settingfollowing commands: * for build <code>dave-image-devel</code> image with <code>DESK-MX8MM-L</code> machine
