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 2010.06-y series (stable)

Download the IGEP U-Boot sources and follow next steps: 

$ wget http://downloads.igep.es/sources/u-boot-arm-2010.06-2.tar.gz
$ tar xzf u-boot-arm-2010.06-2.tar.gz
$ cd u-boot-arm-2010.06-2

Configure for your board with, 

$ make CROSS_COMPILE=arm-none-linux-gnueabi- <board-config>

where:

  • <board-config> is igep0020_config for IGEP v2 platform.
  • <board-config> is 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 local directory.

CHANGELOG

KNOWN ISSUES

  • This versions does not work if you use gcc 4.4 or upper.

U-Boot 2009.11-y series (stable)

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 local directory.
