This article shows how to create a bootable microSD card for the [[AXEL_ULite_and_SBC_Lynx_Embedded_Linux_Kit_(XUELK )|XUELK]] kit by using a simple bash script. The procedure has been tested on a Linux PC running Ubuntu 12 distribution with
*a 16 GB microSD card [1]
*the binary files delivered along with the [[AXEL_ULite_and_SBC_Lynx_Embedded_Linux_Kit_(XUELK)#Downloadable_binary_images|XUELK 1.1.3]].
The resulting card is partitioned as depicted [[AXEL_ULite_and_SBC_Lynx_Embedded_Linux_Kit_(XUELK)#XUELK_microSD_Layout|here]].
The script - named <code>mksd.sh</code> - looks like this:
<pre>
#!/bin/bash
*bootscript: <code>boot.scr</code>
*Linux kernel: <code>uImage</code>
*Device tree blob: <code>imx6ul-lynx.dtb</code>.
This is the list of the binary files that will be used by the script:
<pre>
</pre>
You can now run the script, by passing the following parameters:
*device Device file of the microSD card (<code>/dev/sdc</code> in the example)
*U-Boot image
*path Path of the directory containing the bootcript bootscript file, the Linux kernel image, and the device tree blob*Archive of the target's root file system (compressed as <code>.tar.bz2</code> file).
