Typically U-Boot sources 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 follow next steps:the application.</span>

In 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).
$ wget http:{{Message//downloadsInformation Message|message=The following steps has been tested using '''Ubuntu 16.isee04''' and the '''4.biz/pub/SW_Releases/sources/u-boot-9 version''' of the '''arm-2010.06-3.tar.gz $ tar xzf ulinux-boot'''<span class="mw-arm-2010.06-3.tar.gz $ cd u-boot-arm-2010.06-3headline">'''gnueabihf''' compiler</span>}}
