This page ===<span style="color: #000000;">What is meant to be a starting point for people to learn build a uU-Boot?</span>===<span style="color: #000000;">[http://www.denx.de/wiki/U-Boot/ Das U-Boot] (Universal Bootloader) is an open source, primary boot image and show loader used in embedded devices. Its primary purpose in the shipping system is to people the current status of different u-boot versions for IGEP Processor Boardsload some operating system. </span>
<span style= What "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>
[http://www.denx.de/wiki/U-Boot/ Das U-Boot] (Universal Bootloader) is an open source, primary boot loader used in embedded devices. It is available for a number of different computer architectures, including PPC, ARM, MIPS, AVR32, x86.
= How to cross compile the U-Boot =
==Necessary package==In order to compile and build the Uu-Boot for IGEP PROCESSOR BOARDS you should boot it is '''necessary''' to set up the CROSS_COMPILE variableCross Compiler correctly. In this [[Set this Up the Cross Compiler|post]] it is detailed how to set up correctly the prefix of your toolchain Cross Compiler (including and the trailing dash "-"desired version). 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-gnu-.
As example, once you{{Message/Information Message|message=The following steps has been tested using '''Ubuntu 16.04''' and the '''ve downloaded 4.9 version''' of the u'''arm-linux-'''<span class="mw-boot source, you should follow these steps:headline">'''gnueabihf''' compiler</span>}}
make CROSS_COMPILE=[cross compiler] [board config] make CROSS_COMPILE=[cross compiler]In order to install the Compiler we can use this command:
