This article shows how to create a bootable microSD for the [[DESK-MX6UL-L/General/Release_Notes|DESK-MX6UL-L Release Notes]] kit by using a simple bash script. <br>'''Note:''' Note: Starting from this '''DESK-MX6UL-L 1.0.1''' release the support for the SPL has been introduced in U-Boot. Previous versions of this script will no longer produce a fully functional and bootable microSD card. <br>

The procedure has been tested on a Linux PC running Ubuntu LTS 16MVM released with '''DESK-MX6UL-L 4.0.04 distribution 1''' release with *a 16 32 GB microSD card [1]*a USB SD card reader*the binary files delivered along with the [[AXEL_ULite_SOM/DESK-MX6UL-L/General/Release_Notes#Downloadable_binary_imagesDownloadable_binary_images_3|DESK-MX6UL-L 14.0.10]]

Here is an example that shows how to use this script. Let's assume that the binary files were downloaded in In the <code>desk</code> subdirectory case of the working directory. Before invoking the scriptyou don't have some file on MVM, the following files has to be renamed in order to make them compatible with the default U-Boot environment variablesplease download it from [https:* bootscript: <code>boot//mirror.dave.scr<eu/code>desk-mx-l mirro.dave.eu].  * Linux kernel: We will copy them into <code>uImage<~/code>* Device tree blob: <code>imx6uldesk-lynxmx-som0013-cb002f.dtbl/desk</code> (or <code>imx6ul-axelulite-cb003adirectory.dtb</code> or Needed binary files can be found on <code>imx6ul-axelulite-cb006c.dtbMVM</code>)in the following location:
