U-Boot for IGEP platforms

This page contains information about the customized U-Boot provided by ISEE, as well as the mainline U-Boot. Both can be used on the IGEP platforms.

Environment Settings

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)

Mainline U-Boot, 2012.10 release

See the U-Boot Mainline Series article.

As of the 2012.10 release, mainline U-Boot has got SPL (Secondary Program Loader) integrated, which replaces X-Loader (not IGEP-X-Loader!) in the boot sequence.

Download the source from the git repository: 

$ git clone git://git.denx.de/u-boot.git
$ cd u-boot
$ git checkout v2012.10 -b v2012.10-local

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 results will be a MLO and a u-boot.img file in the u-boot directory.

CAVEAT: Wifi is not set up in this version, the pin mux for the MMC2 interface needs to be configured first!

U-Boot 2010.06-y series (stable)

See the U-Boot 2010.06-y series article.


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

Either download the sources from the git repository 

$ git clone git://git.isee.biz/pub/scm/u-boot-arm.git
$ cd u-boot-arm
$ git checkout v2010.06-3 -b v2010.06-3-local

Or get the snapshot from the downloads directory 

$ wget http://downloads.isee.biz/pub/SW_Releases/sources/u-boot-arm-2010.06-3.tar.gz
$ tar xzf u-boot-arm-2010.06-3.tar.gz
$ cd u-boot-arm-2010.06-3

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)

See the U-Boot 2009.11-y series article.


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

$ git clone git://git.isee.biz/pub/scm/u-boot-arm.git
$ cd u-boot-arm
$ git checkout v2009.11-2 -b v2009.11-2.local

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.
