__TOC__
==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>
===<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. It Its primary purpose in the shipping system is to load some operating system.</span> <span style="color: #000000;">That means that U-Boot is available for necessary to perform a number of different computer architecturescertain task, including PPCbut it's nothing you want to throw any significant resources at. Typically U-Boot is stored in relatively small NOR flash memory, ARM, MIPS, AVR32, x86which is expensive compared to the much larger NAND devices often used to store the operating system and the application.</span>
=How to cross compile the U-Boot=
In order to compile and build the U-Boot for IGEP PROCESSOR BOARDS you should set the CROSS_COMPILE variable. Set this to the prefix of your toolchain (including the trailing dash "-"). So if your toolchain is invoked as say '''arm-linux-gnueabi-gcc''', just chop off that trailing gcc and that's what you use: arm-linux-gnueabihf-.
As example, once you've downloaded the u-boot source, you should follow these steps:
make CROSS_COMPILE=[cross compiler] [board config]
make CROSS_COMPILE=[cross compiler]
