= 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>
This page contains information about the customized ===<span style="color: #000000;">What is U-Boot?</span>===<span style="color: #000000;">[http://www.denx.de/wiki/U-Boot provided by ISEE, as well as the mainline / Das U-Boot] (Universal Bootloader) is an open source, primary boot loader used in embedded devices. Both can be used on Its primary purpose in the IGEP platformsshipping system is to load some operating system.</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>
First of all setup the build environment sourcing this script
<pre>
$ source /usr/local/poky/eabi-glibc/arm/environment-setup
</pre>
or
<pre>
$ source /usr/local/poky/eabi-glibc/environment-setup-arm-none-linux-gnueabi
</pre>
if you have updated your SDK environment to latest version (see [[Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine]])
== Mainline U-Boot, 2012.10 release ==
See ==Necessary package==In order to compile the u-boot it is '''necessary''' to set up the Cross Compiler correctly. In this [[U-Boot Mainline SeriesSet Up the Cross Compiler|post]] articleit is detailed how to set up correctly the Cross Compiler (and the desired version).
As {{Message/Information Message|message=The following steps has been tested using '''Ubuntu 16.04''' and the '''4.9 version''' of the 2012.10 release, mainline U'''arm-Boot has got SPL (Secondary Program Loader) integrated, which replaces Xlinux-Loader ('''not IGEP<span class="mw-X-Loader!headline">'''gnueabihf''') in the [[Boot up sequence|boot sequence]]. compiler</span>}}
