The SAM9G35 and SAM9X35 are actually identical except […]

Android Scores Last in Open Governance Index

Vision Mobile recently released a report about different open source projects analyzing their openness via their Open Governance Index. The full report (45-pages) examines: Open source cultural roots and working upstream vs downstream Open source licenses vs governance models Analysis and classification of governance models In-depth reviews of Android, Qt, Symbian, MeeGo, Mozilla, WebKit, Linux and Eclipse Best practices in creating an open source project The governance index is not only based on the percentage of source code that is open, but on the whole software development including the transparency of the decision making-process, the involvement of the community in all aspects of the project,  compliance requirements and more. There are a total of 13 metrics accross 4  area of governance: Access: availability of the latest source code, developer support mechanisms, public roadmap, and transparency of decision-making Development: the ability of developers to influence the content and direction of the project Derivatives: the ability for developers to create and distribute […]

ARM DS-5 packages are now available and enabled by default for the […]

List of Wireless Standards for Local and Personal Area Networks

While designing your embedded system, you may have to choose between different wireless standards to match your needs. I’ll provide a list a short and mid-range wireless standards, their description and links to  open source software stacks (when available) to help you better understand the different options available.  Wide Area Network wireless network such as LTE, Wimax, etc.. won’t be discussed in this blog entry. Mesh and IP Networks: Wifi (IEEE 802.11): Wifi is probably the most used wireless standard in consumer electronics devices today as it allows users to connect their device to their LAN wirelessly. An access point has a typical range of about 20 meters indoors and up to 100m outdoors. There are 4 standards 802.11a 802.11b, 802.11g and 802.11n. The latest has a theoretical throughput of 300 Mbps. Check out Wikipedia Wifi page for details. The Wi-Fi stack is part of the Linux kernel but you still need specific drivers for a given hardware that may […]

Calao Snowball Development Boards Are now Available

Earlier in February, ST Ericsson had announced the availability of development boards running Linaro based on their Nova A9500 processor. 4 different development kits based on this platform can now be purchased online on Calao store: SKY-S9500-ULP-C22 (SNOWBALL SDK LITE – Without WLAN/BT/GPS) – 155.73 Euros SKY-S9500-ULP-C32 (SNOWBALL PDK LITE – Without WLAN/BT/GPS) – 226.22 Euros SKY-S9500-ULP-C12 (SNOWBALL SDK) – 164.59 Euros SKY-S9500-ULP-C02 (SNOWBALL PDK) – 241.47 Euros The differences between the SDK (Software Development Kit) and PDK (Production Development Kit) are that the former has no expansion connectors, no battery backup for RTC and only support serial over USB port (for Linux console). Finally, the PDK has a larger e-MMC (8GB vs. 4GB). The price mentioned above exclude VAT (if applicable) and shipping costs. Please note that the boards can be shipped to many countries but not anywhere worldwide (e.g. Shipping is not available to Thailand) and you’ll need to allow 7 to 15 days for shipping. The boards feature […]

25 USD ARM11 Linux Computer

raspberry pi prototype

The Raspberry Pi Foundation has designed a 25 USD Linux computer prototype for computer education in both the developing and developed worlds. The foundation, a registered British charity, plans to develop, manufacture, and distribute the USB key-sized computer within the next 12 months. Their computer has a USB key form factor and is designed to plug into a TV or be combined with a touch screen for a low-cost tablet. Provisional specifications: 700MHz ARM11 128MB of SDRAM OpenGL ES 2.0 1080p30 H.264 high-profile decode Composite and HDMI video output USB 2.0 SD/MMC/SDIO memory card slot General-purpose I/O Open software (Ubuntu, Iceweasel, KOffice, Python) This device is much cheaper than OLPC XO (target price 100 USD), however, it does not include a keyboard, display nor batteries, so the market is different as it won’t work in places where electricity is unreliable. Watch the video below of David Braben introducing the 25 USD module. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 […]

Yocto Project: Build Your Own Custom Embedded Kernel Image

The Yocto Project is an open source collaboration project that provides templates, tools and methods to help you create custom Linux-based systems for embedded products regardless of the hardware architecture. The first official release (Yocto Project 1.0) has been made available on the 6th of April 2011. Yocto Project Overview See this short video presentation of the Yocto Project which explains its goals. It’s a complete embedded Linux development environment with tools, metadata, and documentation – everything you need such as emulation environments, debuggers, an Application Toolkit Generator, etc… It is not a new build system however such as buildroot, instead it relies on the Poky build tools that provide an open source development environment targeting the ARM, MIPS, PowerPC and x86 architectures. Here’s what the Yocto Project provides: A recent Linux kernel along with a set of system commands and libraries suitable for the embedded environment. System components such as X11, Matchbox, GTK+, Pimlico, Clutter, GuPNP and Qt (among […]
