In this [[Set Up the Cross Compiler| post]] it is detailed how to set up correctly the Cross Compiler (and the desired version).!| {{Message/Information Message|message=The following steps has been tested using '''Ubuntu 16.04''' and the '''4.9 version''' of the '''arm-linux-|||||'''<span class="mw-|||||headline">'''gnueabihf''' compiler</span>}}
In order to install the Compiler we can use this command:
sudo apt install gcc-arm-linux-gnueabihf
==Download U-Boot Source==
 First of all, will be a distintion between '''NXP'''-processors products and '''ARM'''-processors products. Because there are different kinds of U-Boot depending the of each processor.

==Prepare your U-BOOT==
Once we have downloaded the U-Boot source. We will '''execute''' the file called '''defconfig''' that  (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:
<span style="color: #002d87000000;"> $ make  make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-[defconfigyour_defconfig]</span>* In the following table we will show you our diferent models with their defconfig and an example with our compiler.it can be found the name of each default configuration associated to each IGEP PROCESSORS BOARDS:

==Build your U-BOOT==
After running the defconfig. You can build uthe U-boot Boot by executing this command:  <span style="color: #002d87;"> $ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-</span>
* After doing that we will have our U-Boot ready with their files to execute.** The result for '''Texas Instruments''' processor based board will be a '''MLO''' and '''u-boot.img'''.** The result for  <strong span style="font-sizecolor: 0.939em#000000;">iMX6 </strong><span style make ARCH=arm CROSS_COMPILE="fontarm-linux-gnueabihf-size: 0.939em;">processor based will be a </span><strong style="font-size: 0.939em;">Once the compile process has sucesfully finished, we will find the resulting files inside the u-bootroot folder.imx.</strong>Depending on the processor the generated files will be different:
* 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>
You can install these files, for example, in the boot partition of a SD-card.
