*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:
mkfs.vfat -F 32 -n BOOT "$DRIVE$PART"1 #> /dev/null
mkfs.ext3 -F -L ROOTFS "$DRIVE$PART"2 #> /dev/null
 
# wait for the VM to recognize the uSD
sleep 60
echo "[Copying files...]"
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>
* Linux kernel: <code>desk-mx6-l-4.0.0_uImage</code>
* Device tree blob: <code>desk-mx6-l-4.0.0_imx6dl-sbcx-cb0012.dtb</code>.
 
In the case of you don't have some file on MVM, please download it from [https://mirror.dave.eu/desk-mx-l/ mirror.dave.eu].
We will copy them into <code>~/desk-mx-l/desk</code> directory. Needed binary files can be found on <code>MVM</code> in the following location:

Then copy the ''boot.scr'' into the <code><binaries_dir></code> directories used by the script to create the SD card.
 
===Install Module===
 
To install kernel modules, follow the steps below.
 
<pre>
root@desk-mx6:~# sudo mount /dev/mmcblk0p1 /media
root@desk-mx6:~# tar xvzf /media/desk-mx6-l-4.0.0_modules.tar.gz -C /
</pre>
 
After installation, run the following command to verify that the installation was successful:
 
<pre>
root@desk-mx6:~# ls -l /lib/modules/$(uname -r)
total 304
