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.

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

• 2011-07-29 Release 2010.06-3
  • fix boot hang with DM37x and TPS65950 A3
• 2011-03-07 Release 2010.06-2
  • Set MPU to 1GHz and IVA to 800MHz by default for DM3730
  • Improve GPMC timming for SMSC LAN9221
• 2010-11-03 Release 2010.06-1
  • Improve I2C driver support
  • Use default NET_GPMC configuration to be compatible with DM37XX. This worsens a bit the SMSC LAN9221 throughput.
• 2010-10-19 Release 2010.06-0
  • Add support for DM37XX

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.

CHANGELOG

• 2010-06-15 Release 2009.11-2
  • improve SMSC LAN9221 throughput
  • add support for OMAP3 IGEP module (igep0030)
