==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 available for a number of different computer architectures, including PPC, ARM, MIPS, AVR32, x86to load some operating system.</span>
<span style=How to cross compile the "color: #000000;">That means that U-Boot=In order is necessary to perform a certain task, but it's nothing you want to compile and build the throw any significant resources at. Typically U-Boot for IGEP PROCESSOR BOARDS you should set is stored in relatively small NOR flash memory, which is expensive compared to the CROSS_COMPILE variable. Set this much larger NAND devices often used to store the prefix of your toolchain (including operating system and 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-application.</span>
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]
The result for Texas Instruments processor based board will be a '''MLO''' and '''u-boot.img'''.
==Config filesNecessary package==IGEP0030 DM3730 Module: igep0030_defconfigIn order to compile the u-boot it is '''necessary''' to set up the 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).
