== How to cross compile U-Boot == === Overview of How-To === This How-To is meant to be a starting point for people to learn build the u-boot software for IGEP v2 devices as quickly and easily as possible. This How-To works with the Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine but most of the contents are valid also for other GNU/Linux distributions. We do not issue any guarantee that this will work on other distributions. === Requirements === *'''Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine''' === Feedback and Contributing === At any point, if you see a mistake you can contribute to this How-To. === U-Boot for IGEP v2 ==platforms =
First of all setup the build environment sourcing this script
if you have updated your SDK environment to latest version (see [[Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine]])
==== U-Boot v2009.11 -2 (stable) ==== This version support full OneNAND DDP
Download the IGEP v2 UX-Boot loader sources and follow next steps:
<pre>
$ wget http://downloads.igep.es/sources/ux-bootloader-arm-20091.4.113-10.tar.gz$ tar xzf ux-bootloader-arm-20091.4.113-0.tar.gz$ cd ux-bootloader-arm-20091.4.113-0$ make CROSS_COMPILE=arm-none-linux-gnueabi- omap3_igep0020_config$ make CROSS_COMPILE=scripts/./autobuild.sh arm-none-linux-gnueabi-
</pre>
The result will be :
* For IGEP v2 platform
**x-load-ddp.bin.ift in autobuild/igep0020/flash directory (for OneNAND DDP)
**x-load.bin.ift in autobuild/igep0020/sdcard directory (for SD card)
*For OMAP3 IGEP module
**x-load-ddp.bin.ift in autobuild/igep0030/flash directory (for OneNAND DDP)
**x-load.bin.ift in autobuild/igep0030/sdcard directory (for SD card)
 
 
Download the IGEP U-Boot sources and follow next steps:
 
$ wget http://downloads.igep.es/sources/u-boot-arm-2009.11-2.tar.gz
$ tar xzf u-boot-arm-2009.11-2.tar.gz
$ cd u-boot-arm-2009.11-2
 
Configure for your board with,
 
$ make CROSS_COMPILE=arm-none-linux-gnueabi- <board-config>
 
where:
 
* <board-config> is omap3_igep0020_config for IGEP v2 platform.
* <board-config> is omap3_igep0030_config for OMAP3 IGEP module.
 
Finally, build with
 
$ make CROSS_COMPILE=arm-none-linux-gnueabi-
 
The result will be an u-boot.bin file in arch/arm/boot directory.
