=== Setting the cross-compiler ===
It is assumed that the development environment has been set up properly as described [[DESK-MX6MX6UL-L#Quick_start_guide|here]].
* start the Linux development VM and login into the system
* open a terminal window and ''cd'' into your source code directory
* configure the build environment

=== Running the example on the target ===
Now it is enough to copy the object file in the <code>/home/root</code> rfs directory and [[AXEL ULite/DESK-MX6UL-L/General/Booting_from_NFS | boot from nfs...]]
