Embedded Linux Conference 2015 Schedule – IoT, Cars, and Drones

Embedded Linux Conference 2015 will take place in San Jose, California, on March 23 – 25, 2015, and will focus on Drones, Things and Automobiles. The schedule has been published, and whether you’ll attend or not, it’s always interested to have a look at what will be talked about to have a peak into the future of Embedded Linux, or simply keep abreast with the progress in the field. So as usual, I’ve gone through the schedule, and made my own virtual program with talks that I find interesting. Monday 23rd 9:00 – 9:30 – Driving standards and Open Source to Grow the Internet of Things by Mark Skarpness, Director of Systems Engineering at Intel Billions of devices are beginning to come online, and many of these devices, large and small, are running open source software.  To fuel this innovation, it’s more important than ever for these devices to use a common framework to communicate with each other and the […]

Yocto Project 1.6 “Daisy” Released

The Yocto Project Release 1.6 has just been announced. This release is codenamed “Daisy”, and features Poky 11.0.0, which is the reference system used by the project, but other systems could also be used. The Yocto Project is a framework that creates embedded Linux distributions, and is now being used by many Intel and ARM based embedded boards such as Wandboard, Atmel Xplained, Minnowboard MAX, and the Raspberry Pi. Some of the Yocto Project 1.6 features and updates include: Linux kernel 3.14 and 3.10 LTSI eglibc 2.19, gcc 4.8.2 Support for building Python 3 Toaster web UI for exploring build output Documentation – BitBake user’s manual improvment, and added section explaining how to “Write a New Recipe“. New reference BSP for beaglebone and edgerouter Change to use SHA512 password encryption with shadow by default Various performance improvement, and disk usage reductions. Add support for booting UEFI systems with gummiboot Image / SDK creation code rewritten in Python (previously shell scripts) […]

12MB Minimal Image for Raspberry Pi using the Yocto Project

Last year, I wrote instructions and provided a download link about a minimal image for Raspberry Pi based on Raspbian. The compressed image is 84MB, and the good thing about it is that you can just use apt-get to install packages. The problem is that it’s not actually that small as once it is uncompressed the rootfs is still a massive 414 MB. So today, I’ll explain how to create a smaller (and custom) image using the Yocto Project, a platform that let you build an embedded Linux distribution matching exactly your project’s requirements. Other advantages are that the build is configurable with config files, so it’s easily reproducible with a few command lines, and it might turn out to be useful to learn more about the Yocto Project as many boards and SoC are now making use of the framework, including Freescale i.MX6 (Wandboard, Olinuxino-imx233, Sabrelite, etc…), the Beagleboard, and Minnowboard to name a few. If you just want […]

Yocto Project 1.4 “Dylan” Release

The Yocto Project Release 1.4 has just been announced. This release codenamed “Dylan” and based on Poky 9.0.0 is the sixth release of the project.
