How to cross compile X-loader

Overview of How-To

This How-To is meant to be a starting point for people to learn build the x-loader software for IGEP v2 devices as quickly and easily as possible.

This How-To works with the Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine but most of the contents are valid also for other GNU/Linux distributions. We do not issue any guarantee that this will work on other distributions.

Requirements

• Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine

X-loader for IGEP v2

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 v1.4.2-2 (stable)

This version supports full OneNAND DDP

Download the IGEP v2 X-loader sources and follow next steps:

$ wget http://downloads.igep.es/sources/x-loader-1.4.2-2.tar.gz
$ tar xzf x-loader-1.4.2-2.tar.gz
$ cd x-loader-1.4.2-2
$ scripts/./autobuild.sh arm-none-linux-gnueabi-

The result will be :

• 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)

X-loader mainline tree (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.myigep.com

$ git clone git://git.igep.es/pub/scm/x-loader.git
$ cd x-loader

and build with

$ cd x-loader
$ scripts/./autobuild.sh arm-none-linux-gnueabi-

The result will be :

• 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)
