Pengutronix uCLinux 3.2 for Energy Micro EFM32 Cortex-M3 Gecko MCUs

Energy Micro and Pengutronix announced that they will be demonstrating µClinux for Cortex-M3 on the EFM32 Gecko range (Leopard and Giant) of MCU during  Embedded World Conference 2012 on 28 February – 1 March 2011 in Nuremberg, Germany. Pengutronix’s port of µClinux features the Linux 3.2 kernel, providing the cost and time-to-market benefits of Linux operating system, while maintaining low current consumption of just 1.6mA when in idle mode. The company explains that using µClinux reduces design cycles and accelerates time-to-market by giving the designer access to ready-made system functions such as IP connectivity, file systems, and multi-tasking. Users can also employ the broad range of free software and drivers available as open source, within a robust, portable open source framework. The teaser video (below) shows that the demo platform (Giant Gecko Development Kit?) uses 4 MB of RAM (755 KB used after boot-up) and the MCU delivers 9.07 Bogomips. […]

Run Windows 7 (or Any OS) on Android Tablets with PCoIP Protocol

Teradici has developed PCoIP (PC-over-IP) protocol, a technology that allows to  run a full desktop remotely over the network on thin clients, desktops, integrated displays, laptops and even Android tablets. The PCoIP protocol compresses, encrypts and encodes the entire computing experience at the data center and transmits it ‘pixels only’ across any standard IP network to stateless PCoIP zero clients. The PCoIP protocol is implemented in silicon for hardware accelerated performance and in software in VMware View. It supports high resolution, full frame rate 3D graphics and HD media, multiple large displays, full USB peripheral connectivity, and high definition audio all via LAN or WAN networks. A typical network made of PCoIP clients is shown below. Teradici emphasizes three key features of PCoIP technology: PCoIP technology uses host rendering Most other remote desktop technologies uses client rendering which may not be optimal and requires somewhat powerful clients. PCoIP uses host […]

Raspberry Pi Codecs and Graphics/Video APIs

The Raspberry Pi Foundation has announced which codecs and API would be supported in the Raspberry Pi. The Raspberry Pi board will support the following Graphics and Video API via a set of closed source libraries that give access to the GPU acceleration features: OpenGL ES 2.0 –  OpenGL is a 3D Graphics API defined by the Khronos Group. OpenVG – OpenVG is a 2D vector drawing API also defined by the Khronos Group. EGL – EGL is the interface between Khronos rendering APIs such as OpenGL ES or OpenVG and the underlying native platform window system. OpenMAX IL – OpenMAX supplies a set of API’s that provides abstractions for routines used during audio, video, and still images processing. OpenMAX defines 3 layers, Raspberry Pi library will provide an interface to the IL layer, which provides an interface between media framework such as Gstreamer and a set of multimedia components.

Spark: Linux Tablet with KDE based Plasma Active

This must be the very first Linux tablet available on the market. Spark sports an open Linux stack on unlocked hardware and comes with an open content and services market. The user interface is Plasma Active running on KDE. Here are the technical specifications: CPU: ARM AMLogic (Cortex-A9) @ 1 GHz Mali-400 GPU 512 Mo RAM 7″ multi-touch capacitive touchscreen 4 Go Flash SD card slot WiFi, 3G (GSM), HDMI (1080p), 2 mini-USB ports Battery: 3000 mAh at 7,4 volts or 6000 mAh at 4,7 volts Weight: 355 grams You can see Plasma Active interface in the video below: The tablet will cost 200 Euros (about 270 USD). They did not provide availability, but promised further information on Tuesday. You can learn more about the user interface, getting a binary image and/or getting info to development apps for the platform on Plasma Active website.

HUD (Head-Up Display) Comes to Ubuntu 12.04

Ubuntu has announced Head-Up Display (HUD) for Ubuntu 12.04 (Precise Pangolin) a contextual search interface that could, as Canonical expects, ultimately replace menus in Unity applications. So when Ubuntu 12.04 is released in April 2012, it will be the first LTS (Long Term Support) Ubuntu version with the Unity interface and the new HUD feature. I like HUD, as I find it similar to what is done in Windows 7 and what could be done with Google Desktop in Windows XP previously, although Ubuntu HUD goes further as it includes menus in the search. What I would NOT like however, is that they completely remove menus. I’d like to see it as a complement of menus (Which will be the case in 12.04), but this does not seem to be Canonical’s intention for future versions of Ubuntu (12.10 and beyond), as they want to replace menus with HUD. HUD will […]

Linaro 12.01 Release with Kernel 3.2 – Android 4.0.3

Linaro has just released version 12.01 based on Linux Kernel 3.2 and Android ICS upgraded to 4.0.3.  A lot of work has been done to have video hardware decoding on OMAP 4 (in GStreamer) enabling Pandaboard to run Ubuntu TV and XBMC with Video HW acceleration. Prebuilt binaries for Linaro GCC and Linaro GDBare now available which means you don’t need to use Ubuntu with Linaro Toolchain. It has been tested with Debian 6.0.2, Fedora 16, openSUSE 12.1 and Red Hat Enterprise Linux Workstation 5.7 and should run on any Linux Standard Base 3.0 compatible distribution. Windows binaries are also available and known to work on Windows XP Pro SP3, Windows Vista Business SP2 and Windows 7 Pro SP1. Here are the highlights of the release: Android Linaro’s ICS has been upgraded to 4.0.3. Linaro Android ICS builds are now optimized using -O3 with the Linaro Toolchain. Click through builds […]

Cross-compiling libavg 1.7 for ARM on Debian

libavg is a high-level development platform for media-centric applications using Python as scripting language and written in C++ and I’ve already written a post to cross-compile libavg 1.6 in Ubuntu (with linaro cross toolchain) and using Beagleboard qemu image. Since I’ve doing some preparation work to have software running on the Raspberry Pi and that the latter won’t support Ubuntu, I’ve had to cross-compile it again. This time, I’ve found a cleaner way to do the cross-compilation with dpkg-cross and xapt tools which can load the required armel package to the arm toolchain. Those tools really make life easy, as previously (a few years ago), I would have had to cross-compile all dependencies manually. Here are the steps I followed: Install Emdebian ARM Cross Toolchain and Tools in Debian. Download libavg 1.7 source code

Extract it

Install the following armel development packages: sudo /usr/share/pdebuild-cross/xapt -a armel libpango1.0-dev libavformat-dev […]
