Contents
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-2010.06-1.tar.gz $ tar xzf u-boot-arm-2010.06-1.tar.gz $ cd u-boot-arm-2010.06-1
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
- 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
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.
CHANGELOG
- 2010-06-15 Release 2009.11-2
- improve SMSC LAN9221 throughput
- add support for OMAP3 IGEP module (igep0030)
