*a 32 GB microSD card [1]
*a USB SD card reader
*the binary files delivered along with the [[DESK-MX6-L/General/Release_Notes#Downloadable_binary_images_2Downloadable_binary_images|DESK-MX6-L 4.0.0]].
The resulting card is partitioned as depicted here below:
Here is an example that shows how to use this script. We use here files delivered with [[DESK-MX6-L/General/Release_Notes#Downloadable_binary_images_2Downloadable_binary_images|DESK-MX6-L 34.0.0]] release. Before invoking the script, the following files has to be renamed in order to make them compatible with the default U-Boot environment variables:
* bootscript: <code>boot.scr</code>
* splash image: <code>splash_image.bmp</code>
