→Introduction
[[DESK-MX8M-L | DESK-MX8M-L]] 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>desk-mx8m-l-rel-2.0.0-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>smart</code> tool. Please refer to [[Advanced_use_of_Yocto_build_system_([[DESK-MX8M-L | DESK-MX8M-L]])#Using_pre-built_package_archive|this section]] 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.
