This page explain how to '''create a microSD card''' to boot IGEP boards with '''software distributions ( yocto, Ubuntu, Debian ...)'''.
* Now we can see an image of which are the steps to boot any module.
With a general processor all start with MLO file and U-Boot.img. Also it is the same procedure for Freescale- NXP. If you want to see how to create these files follow this [[The bootloader U-Boot|link]].
Next step is that once the processor is initialized,call the linux kernel making the execution of your operative system available.
Finally your OS runs and you can initialize the board correctly

* The microsd card must be content at latest 2 partitions.
* The first one must be primary partition with the boot flag mark and formated using FAT(16 or 32) file system.
''The processor when boot ONLY load and execute the MLO program and ignore all the rest it's the X-loader(MLO) the program responsible to load the next programs such kernel or uboot if you use this last one approach.''

You should see something like this:

<div style="text-align: left;">{{Message/Information Message|message=The following steps has been tested using an Ubuntu 16.04}}</div>
<div style="text-align: left;">First of all it is important to detect which device is our microSD Card. In order to do that we can follow this instructions in a Linux terminal:</div>
<div style="text-align: left; padding-left: 30px;">'''1-''' Clean the ''dmesg'' information:</div>
sudo dmesg -c
'''2-''' Insert the microSD Card and show the ''dmesg'' information:
==<span id="Install_GParted" class="mw-headline">Downloading GParted</span>== dmesgIn order The result have to prepare a micro SD with your already generated u-boot you need be similar to flash the u-boot.imx using the command dd.this:
It is important to prepare your micro SD card first creating a partition that leave some free space for the u-boot.imx. It can be used GPARTED as it is shown in the image:
[[File:GPARTEDdev.png|center|713x201px]]
<div style="text-align: left;">We can see the name of our device in the system: '''/dev/sdX''' where X is the character assigned by our system, in this case /dev/sdc'''.'''</div>
<div style="text-align: left;">Now we have to ensure that the MicroSD Card is completely clean. We can use the following command to do that:</div>
sudo dd if=/dev/zero of=/dev/sdX bs=1024 count=1024
Where '''X''' is the character returned previously by your system, for example, in the previous situation:
And it can be installed with this command sudo dd if=/dev/zero of=/dev/sdc bs=1024 count=1024Before use anyway of partition one good practise is unmount the dev where is inserted the SD.-> <code>umount /dev/sdx</code>
<pre>sudo apt-get install gparted</pre><span style="color: #000000;">Now we will see all are ready to create the steps for this partition with GPARTED after another brief explanation of other methodcorresponding partitions in our MicroSD Card.</span>
==How to partition the MicroSD card==
<div style="text-align: left;">There are several ways to partition a MicroSD Card. In this post we are using the GParted tool that can be installed as:</div>
