The bootloader X-loader

X-loader 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)

X-loader v1.4.4-3 (stable)

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

$ wget http://downloads.igep.es/sources/x-loader-1.4.4-3.tar.gz
$ tar xzf x-loader-1.4.4-3.tar.gz
$ cd x-loader-1.4.4-3
$ 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)

X-loader 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/x-loader.git
$ cd x-loader
$ git checkout origin/for-next -b for-next

and build with

$ cd x-loader
$ make CROSS_COMPILE=arm-none-linux-gnueabi- igep00x0_config 
$ make CROSS_COMPILE=arm-none-linux-gnueabi-

The result will be :

• x-load.bin.ift in ./ directory
