Tech Focus: Making the case for open source
HIGHLIGHTS
The Compelling Case for Open Source Embedded Tools
Validating your GNU platform toolchain: tips and techniques
Open Embedded: An alternative way to build embedded Linux distributions
Standardizing on a common embedded Eclipse IDE
Editor's Note
The speed with which Google's Android platform has captured the imagination of embedded systems developers has been a boon for all things open source. Not only is a Linux operating system distribution at the core of the mobile development platform, but a wide range of open source tools, including the GNU tool chain and the Eclipse IDE , are used and promoted as preferred methods of software development.
No matter how wedded you are to the security that proprietary tools and RTOSes provide in terms of reliable operation and long-term support, the fact that Android is so widely used in mobile designs and is moving into a number of non-hard real-time embedded apps is a good reason to familiarize yourself with the variety of open source tools and building blocks available.
Collected in this issue of the Embedded Tech Focus is a repository of open source related design articles, product news stories, white papers and webinars that you can use as resources. Of these, my Editor's Top Picks are:
“Understanding Android's strengths and weaknesses , ” where Juan Gonzales, Darren Etheridge, and Niclas Anderberg discuss a number of other less-used open source tools such as X11/KDE, Qt/Embedded, Packet Video OpenCore, Google Starbright, and OpenMax.
“Do it yourself embedded Linux development tools , ” in which Alexander Sirokin provides a good breakdown of all of the open source resources available for use when doing Linux development, with a particular focus on the smaller, less well-known but useful tools such as BusyBox, Wine, VirtualBox, Emacs, Cscope, Insight and OProfile.
“Open Embedded: an alternative way to build embedded Linux distributions,” in which Nick Lethaby and Denys Dmytriyenko provide an overview of the Open Embedded Linux build environment with particular attention to BitBake, a cross-compilation and build tool.

Robert Day of LynxWorks provides an overview of the Eclipse open-source IDE framework that is integral to many embedded systems development tools, roll-your-own, open source, and proprietary.
Debugging of embedded Linux applications on ARM9/ARM11 processors
Embedded Linux as an operating system for modern ARM processors? Maybe not such a bad idea? Linux is a multitasking operating system and therefore, each process must be assigned its own process address space. However, this partitioning greatly complicates the debugging of processors and inter-process functionality. So what can be done to tackle this? This article illustrates some possibilities how you can successfully achieve your goal.
