Cost-effectiveness, excellent quality, and open standards - these are just a few benefits of open-source technologies that have made Linux the right choice for many device software developers. By leveraging advances from the open-source community, Linux has rapidly evolved as a viable, flexible, and extensible platform for building a broad range of tools and devices once constrained by technical limitations. Major industries, including networking, telecommunications, aerospace and defense, automotive, and consumer devices, have built and deployed devices running on embedded Linux platforms. This presentation is about Linux for device software development. The speaker gives insights on where the industry stands, current trends, and when it makes sense to start using Linux. He covers the variety of Linux distributions available today, compares the challenges of rolling your own versus employing the pre-packaged Linux distribution that comes with hardware boards, and discusses the power of a commercial-grade solution.
