Embedded Linux Conference Europe (ELC-E) 2012 wrapped up last week in Barcelona. By far, the most popular embedded platform of choice for demonstrations was BeagleBone. Here are four examples that include links to the slides taken from the eLinux wiki ELC-E presentation page. Videos of the presentations should be available from Free Electrons soon.
Commodore 64 demoscene with "What's Old Is New: A 6502-based Remote Processor". While this might seem like a bit of a throw-back, many modern issues and solutions were explored to give us this taste of the past, including the Linux remoteproc/virtio interfaces to remote processors, the AM335x PRUSS processor that is extremely adept at bit-banging and the Fritzing design tool. Matt has also shared a picture of his wiring handy-work.
Supporting 200 Different Expansionboards: The Broken Promise of Devicetree". If you frequent #beagle, you probably already know that Koen isn't easy to please and so the title shouldn't be much of a surprise. You might then be surprised to note on the first slide where "broken" has been scratched out! We certainly aren't there yet, but the device tree maintainers and AM335x kernel developers are starting to address the unique opportunities around BeagleBone cape expansion boards in the mainline Linux kernel, making a reality out of the dream of supporting hundreds of boards with a single kernel distributed ahead of the add-ons!
The continued enthusiasm of the embedded Linux community is just one element of what makes BeagleBoard.org successful, but it probably makes me happier than any other. With many of these developers moving the state of the Linux kernel ahead and even looking at sharing their hardware ideas in the BeagleBone Cape Plug-in Board Design Contest, I see a bright future where the largest collaborative software project of all time fully embraces the hardware and maker communities such that we can build a world where individuals and even children can reproduce electronics and computers down to the circuit level, not simply build on black magic.
