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.

U-Boot for IGEP platforms

First of all setup the build environment sourcing this script 

$ source /usr/local/poky/eabi-glibc/arm/environment-setup

or 

$ source /usr/local/poky/eabi-glibc/environment-setup-arm-none-linux-gnueabi

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)

Download the IGEP X-loader sources and follow next steps: 

$ wget http://downloads.igep.es/sources/x-loader-1.4.3-0.tar.gz
$ tar xzf x-loader-1.4.3-0.tar.gz
$ cd x-loader-1.4.3-0
$ scripts/./autobuild.sh arm-none-linux-gnueabi-

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.

U-Boot mainline tree (development)

Note: The 'master' branch is where the development work takes place and you should use this if you're after to work with the latest cutting edge developments. It is possible trunk can suffer temporary periods of instability while new features are developed and if this is undesirable we recommend using one of the release branches. Use ONLY for development purposes.

Clone the GIT repository from git.igep.es 

$ git clone git://git.igep.es/pub/scm/u-boot-arm.git
$ cd u-boot-arm
$ git checkout origin/u-boot-2009.11.y -b u-boot-2009.11.y

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.
