__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;">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>
=How to cross compile the U-Boot=
<span style="color: #000000;">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-.</span>
<span style="color: #000000;">As example, once you've downloaded the u-boot source, you should follow these steps:</span>
<span style="color: #002d87;">make CROSS_COMPILE=[cross compiler] [board config]
make CROSS_COMPILE=[cross compiler]</span>
<span style="color: #000000;">The result will be a MLO and a u-boot.img file. You can install these files, for example, in the boot partition of a SD-card.</span>
==Necessary package==
