==Overview==
<span style="color: #000000;">This page is meant to be a starting point for people to learn build a u-boot image and show to people the current status of different u-boot versions for IGEP Processor Boards.</span>

==Prepare your U-BOOT==Once we have downloaded we the U-Boot source. We will '''execute ''' the file called '''defconfig,'''  (default configuration) that it variates in function of each model. In order to load the default configuration of the target board, we have to write the following command:

==Build your U-BOOT==
After running the defconfig. You can build the U-Boot by executing this command:
====<span id="Build_u-boot" class="mw-headline">Build u-boot</span>====You can build u-boot executing this command:  <span style="color: #002d87000000;"><code><span style="color: #002d87;">$ make  make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-</span></code></span>   * The result for '''Texas Instruments''' processor based board Once the compile process has sucesfully finished, we will be a '''MLO''' and '''find the resulting files inside the u-bootroot folder.img'''.* The result for <strong style="font-size: 0.939em;">iMX6 </strong><span style="font-size: 0.939em;">Depending on the processor based the generated files will be a </span><strong style="font-sizedifferent: 0.939em;">u-boot.imx.</strong>  You can install these files, for example, in the boot partition of a SD-card.  
* The result for '''ARM''' processor based board will be a '''MLO''' and '''u-boot.img'''.
* The result for '''Freescale'''-'''NXP'''<strong style="font-size: 0.939em;"> </strong><span style="font-size: 0.939em;">processor based will be a </span><strong style="font-size: 0.939em;">u-boot.imx.</strong>
Finally we can copy this files in a '''boot device''', for example, a microSD Memory Card. It is explained in the following [[How to prepare a bootable MicroSD Card|post]].
{{Message/Information Message|title=TITLE|message= <span style="color: #000000;">In case of the Freescale-NXP Porcessor Boards, it is not possible to copy directly the u-boot.imx file. It is necessary to copy in the first blocks of the boot device using the dd command. It is explained in the following post [[How to prepare a bootable MicroSD Card|How to prepare a bootable MicroSD Card]].</span>}}
