= U-Boot for IGEP platforms =__TOC__
==Overview==<span style="color: #000000;">This page contains information about the customized Uis meant to be a starting point for people to learn build a u-Boot provided by ISEE, as well as boot image and show to people the mainline Ucurrent status of different u-Boot. Both can be used on the boot versions for IGEP platformsProcessor Boards.</span>
== Environment Settings =<span style="color: #000000;">What is U-Boot?</span>===<span style="color: #000000;">[http://www.denx.de/wiki/U-Boot/ Das U-Boot] (Universal Bootloader) is an open source, primary boot loader used in embedded devices. Its primary purpose in the shipping system is to load some operating system.</span>
First of all setup the build environment sourcing this script<prespan style="color: #000000;">$ source /usr/local/poky/eabiThat means that U-glibc/arm/environmentBoot is necessary to perform a certain task, but it's nothing you want to throw any significant resources at. Typically U-setupBoot 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.</pre>or<prespan>$ 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 ==
As of the 2012.10 release, mainline U-Boot has got SPL (Secondary Program Loader) integrated, which replaces X-Loader ('''not IGEP-X-Loader!''') in the [[Boot up sequence|boot sequence]].
Download ==Necessary package==In order to compile the source from u-boot it is '''necessary''' to set up the git repository:Cross Compiler correctly. In this [[Set Up the Cross Compiler|post]] it is detailed how to set up correctly the Cross Compiler (and the desired version).
$ git clone git:{{Message//gitInformation Message|message=The following steps has been tested using '''Ubuntu 16.denx04''' and the '''4.de/u9 version''' of the '''arm-boot.git $ cd ulinux-boot $ git checkout v2012.10 '''<span class="mw-b v2012.10-localheadline">'''gnueabihf''' compiler</span>}}
Configure for your board withIn order to install the Compiler we can use this command:
$ make CROSS_COMPILE=sudo apt install gcc-arm-nonelinux-linuxgnueabihf==Download U-Boot Source== First of all, will be a distintion between '''NXP'''-gnueabiprocessors products and '''ARM'''- <boardprocessors products. Because there are different kinds of U-config>Boot depending of each processor.
