Android and Tizen on Intel Medfield Atom Z2460 (Video Interview)

Intel announced the MedField Soc (Atom Z2460) targeted at smartphones and tablet and showcased a smartphone reference design running Android based on this platform. Mike Bell GM of Intel’s Mobile Communications Groups (MCG) has been interviewed by EETimes. He talks about Intel entry into the mobile phone market and explains that MedField boasts similar power consumption than top competitors with better performance (3 to 4 times faster in some web browser benchmark). He mainly talks on what they have done to port Android on the platform (and shows Angry Bird a lot) and what you may expect in the future. He also quickly mentioned Tizen. Here’s the original EETimes’ article. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011. www.cnx-software.com

Intel or ARM NoteBook? Lenovo Says Both

Lenovo has announced the ThinkPad X1 Hybrid notebook which features an Intel Core processor (i3, i5, or i7 depending on the model) AND a Qualcomm Dual core ARM processor, allegedly a Qualcomm APQ8060 and runs both Windows 7 and a custom version of Linux. My first reaction when I read the news was: “What a stupid idea!” :~/ The ThinkPad X1 Hybrid has 13.3″ HD display with 1366×768 resolution and built with Gorilla Glass. The laptop also features an HD webcam, a fingerprint reader, an encrypted hard disk drive, an HDMI port, USB ports, and Intel’s Wireless Display (WiDi) technology. RapidCharge technology charges to 80% capacity in 30 minutes, i.e. approximately the time it takes to take a shower and cook an egg… (Not my idea, see promo video below). The only thing that can possibly justify having two different processors on the machine is the Instant Media Mode (IMM) […]

Enable OpenGL 2.0 and WebGL for Intel GMA3150 in Ubuntu

I wanted to use WebGL in my Acer Aspire One D255E netbook that uses an Intel GMA 3150 onboard graphics card, but it did not work in Chromium nor Firefox. WebGL requires OpenGL 2.0 support, but I found out I only had support for OpenGL 1.4:

But I found out it was possible to enable OpenGL 2.0 for GMA 3150 in Linux by installing and running driconf:

and clicking on “Enable limited ARB_fragment_shader support on 915/945.” and “Enable stub ARB_occlusion_query support on 915/945.” options. They are not enabled by default because they do cause problems. After those two options were enabled, OpenGL 2.0 was enabled.

But I still could not use WebGL in either Chromium nor Firefox, so I decided to install the latest version of Mesa (7.11) with indirect rendering (software) enabled with libOSMesa:

Even with the latest Mesa library, I could not use WebGL […]

Tuning Linux For Embedded Systems – ELCE 2011

Darren Hart, Intel’s Open Source Technology Center, gives a 5 step method to optimize Linux (image size, memory footprint and boot time) for embedded systems at Embedded Linux Conference Europe 2011. Abstract: Although embedded systems are less and less resource constrained, there is still a lot of demand for minimizing the image size, runtime memory usage, and boot time. The firmware, kernel configuration, hardware initialization, boot-time arguments, start-up scripts, and library sizes are all examples of things with a direct impact on your image size and/or boot time. There are several core processes involved with minimizing the size of an image, which has a direct impact on runtime memory usage and boot time. The focus is on configuration techniques that get you most of the way there and follow-up with source-level customizations that get you the rest of the way.

The Yocto Project Eclipse Plug-In – ELCE 2011

Jessica Zhang is Software Engineer at Intel and works on Yocto Application Development Kit (ADT) and its Eclipse plug-in. She presented Yocto Project Eclipse Plug-in at Embedded Linux Conference Europe 2011. Abstract: Yocto project is an open source collaboration project that aims at helping embedded Linux software developers, either for system or application development. The Yocto Eclipse plug-in provides an effective integrated development environment that is based on the widely adopted Eclipse CDT and TCF extensions. It allows user to seamlessly interact with various Yocto project development tools. Yocto 1.0 targeted application developers via cross toolchains and sysroot setup, with remote deploy, debug and analysis. For 1.1, we have added support in the Yocto Eclipse plug-ins for system development through interaction with the bitbake UI interface for a Yocto bitbake commander type project. This talk will demo the end-to-end usage flows of Yocto Eclipse plug-in for both system and application […]

Developing Embedded Linux Devices Using the Yocto Project – ELCE 2011

Presentation entitled “Developing Embedded Linux Devices Using the Yocto Project and What’s new in 1.1” by David Stewart, Intel, at Embedded Linux Conference Europe 2011. Abstract: The Yocto Project is a joint project to unify the world’s efforts around embedded Linux and to make Linux the best choice for embedded designs. The Yocto Project is an open source starting point for embedded Linux development which contains tools, templates, methods and actual working code to get started with an embedded device project. In addition, the Yocto Project includes Eclipse plug-ins to assist the developer. This talk gives a walk-through of the key parts of the Yocto Project for developing embedded Linux projects. In addition, features are described from the latest release of Yocto (1.1). At the end of the talk, developers should be able to start their own embedded project using the Yocto Project and use it for developing the next […]

The Linux NFC Subsystem – ELCE 2011

Lauro Ramos Venancio, Instituto Nokia de Tecnologia and Samuel Ortiz, Intel give a presentation about the NFC subsystem in Linux at Embedded Linux Conference Europe 2011. Abstract: NFC (Near Field Communication) is a wireless protocol mostly designed for fast information reading and writing from nearby devices and tags. It also allows NFC devices to establish a transport layer link and exchange larger chunks of data. While Android ships with its own multi platform NFC stack writing HCI frames to a raw character device and supporting one single device, Linux is currently missing any kind of generic and clean NFC support, from both kernel and user space (cnxsoft: Since end of last month, this is not the case as Linux 3.1 supports NFC). Therefore, a new socket family for NFC, along with a kernel netlink API for high level NFC commands passing is being developed. An NFC user space daemon abstracts […]

Yocto Project Release 1.1 Announced

The Linux foundation announced Yocto Project Release 1.1 today. This release codenamed “Edison” and based on Poky 6.0 is the the second release of the project, one year after it was announced in October 2010 to provide developers with greater consistency in the software and tools they’re using across multiple architectures for embedded Linux development. The Yocto Project reached the following milestones during the last year: Alignment of OpenEmbedded technology and the inclusion of OpenEmbedded representation in the Yocto Project governance structure. The projects share a common core that consists of software build recipes and core Linux components that prevent fragmentation and reinforce the OpenEmbedded methodology as an open standard for embedded Linux build systems. Contribution of tools and technologies such as Cross-prelink, EGLIBC, Pseudo, Shoeleather Lab (for automated testing) and Swabber have been contributed from Intel, Mentor Graphics, MontaVista Software and Wind River. Commercial adoption with examples such as […]
