= U=Overview==<span style="color: #000000;">This page is meant to be a starting point for people to learn build a u-Boot boot image and show to people the current status of different u-boot versions for IGEP platforms =Processor Boards.</span>
<span style== Environment Settings =="color: #000000;">That means that U-Boot is necessary to perform a certain task, but it's nothing you want to throw any significant resources at. Typically U-Boot is stored in relatively small NOR flash memory, which is expensive compared to the much larger NAND devices often used to store the operating system and the application.</span>
{{Message/Information Message|message== UThe following steps has been tested using '''Ubuntu 16.04''' and the '''4.9 version''' of the '''arm-Boot 2010.06linux-y series (stable) ='''<span class="mw-headline">'''gnueabihf''' compiler</span>}}

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> 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.
