Who Am I ?
What is embedded Linux ?
Linux kernel
Open source components
Specific applications
Demo hardware platform
● Fairly typical ARM evaluation platform
● Many devices: Screen, Network, SD card, USB ...
● Used to develop prototypes
● Reference to design specific board Atmel AT91SAM9G45 (ARMv5) processor
Building an embedded Linux system
Binary distributions Building tools
PTXdistOpenWRT● Automate system
reconstruction from source code
● Support many more CPU architectures
● High flexibility on components configuration
● Most used solution
● Heavyweight systems
● Not all CPU architectures supported
● Not flexible to choose the configuration for each components
What is Buildroot ?
● Simple build system - http://buildroot.org :– automate the cross compilation process – generate kernel images, file system and bootloader
● Developped by :– an open source community– vendor neutral– under GPLv2
● Actively developped and used for many products● Written in make language ● Choice of options in configuration interface

Why Integrating Buildroot in Eclipse ?
System developers Application developers
Why Integrating Buildroot in Eclipse ?
● Open source IDE for Application developers– Preconfigured with the cross compilation toolchain– Transfer / Execute remote application– Remote Debug
Buildroot toolchain Eclipse plugin
● Integrate the toolchains to Eclipse CDT– Read the toolchain description file (/home/.buildroot-
eclipse.toolchains)– Register dynamically the toolchains in CDT– Project toolchain selection:
● Set the C/C++ compiler path● Integration with scanner information● Remote Launch configuration● Remote Debug configuration
Integration with CDT
● Inspired by the Eclipse Blackfin plugin and the GNU ARM Eclipse plugin
● Use CDT extension point : org.eclipse.cdt.managedbuilder.core.buildDefinitions
– with a dynamicElementProvider and according to the Buildroot configuration file:
● declare toolchain ● projectType
Integration with CDT
● Missing dynamic extension points in CDT ?● scanner configuration discovery profile● launch configuration
Integration with CDT
Buildroot Eclipse Update-site
● Update-site integrating embedded Linux tools :– Buildroot Toolchain Eclipse Plugin– CDT – Linux tools– Autotools …
● Make a Ready-to-Use development platform for embedded Linux
Buildroot Eclipse plugin demonstration
Availability
● Buildroot : http://buildroot.org● Buildroot Eclipse plugin sources (EPL licence):
– https://github.com/mbats/eclipse-buildroot-toolchain-plugin– Also contains the Buildroot patch to add Eclipse toolchain
generation menu● Buildroot Eclipse bundle sources :
https://github.com/mbats/eclipse-buildroot-bundle● Buildroot Eclipse bundle update-site (based on Eclipse
3.8) : available soon
Future work
● Create an Eclipse bundle with Tycho which will be available on Buildroot website
● Integrate :– pkg-config– RX-TX– LTTNG– Other relevant Eclipse plugins for embedded Linux
development● Write documentation and make a video tutorial
