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

*the binary files delivered along with the [[Axel_Embedded_Linux_Kit_(XELK)AXEL_ULite_SOM/DESK-MX6UL-L/General/Release_Notes#Downloadable_binary_images|DESK-MX6UL-L 1.0.1]]The resulting card is partitioned as depicted [[Axel_Embedded_Linux_Kit_(XELK)#XELK_microSD_Layout|here]]below:

* bootable partition (mmcblk0p1, vfat) containing:** binary images (u-boot and kernel images)* root file system partition (mmcblk0p2, ext3)** root file system binaries and init scripts The script - named <code>desk-mx6ul-l-1.0.0_mksdmksd.sh</code> - looks like thiscan be realized with the following code:
