Syntro 0.5.0 Cross-platform C++ Framework for Distributed Sensor Networks

Pansenti has announced the first release of Syntro (version 0.5.0), a cross-platform framework for creating distributed sensor networks. Syntro is an open source C++ library and a set of applications based on Qt 4.7. The source code is released under the GPL license. Syntro has been developed on the following platforms: Linux Fedora 16 Ubuntu >= 10.10 Mac OS 10.7 Windows 7 Syntro can run on x86 targets as well as ARM based Pandabord, Beagleboard and Beaglebone development boards (Ubuntu only). Syntro is based on the following “SyntroCore” applications: SyntroExec – Start up and management of Syntro apps. SyntroControl – Message switching and multicast distribution. SyntroStore – Multicast stream capture. SyntroCFS – Cloud file storage. SyntroReplay – Multicast stream generation. SyntroLog – Network-wide logging. Some demo applications using one or more webcams and the OpenCV library are also available: SyntroCamera – Capture a stream from a video device (such as […]

Locux: 15 USD Freescale i.MX233 System On Module

These days, low cost boards seem to pop-up a bit everywhere…  Featuring the same processor as Olimex OLinuXino, the Locux board will be powered by a Freescale i.MX233 with 64 MB and boot from a microSD card (no NAND on the board). This project is quite different from other low cost board projects, since it is a system on module (SoM) and will require a carrier board to access peripherals such as Ethernet, USB Host and video output, although  the developers managed to boot it with a simple breadboard. The developers also explain that this board stands apart as it does not feature any BGA parts and can be hand soldered, which could be an advantage when sourcing the boards and some hobbyist may also like to do the soldering themselves. The Raspberry Pi is still hard to get and the some other low cost boards such as the Beaglebone […]

Raspberry Pi Schematics (Model B) are Available

Now that Raspberry Pi passed all certifications and a few boards are out in the wild, the Raspberry Pi foundation has released the schematics of model B, bringing the Raspberry Pi board closer to becoming an open hardware platform like Texas Instruments Beaglebone or Beagleboard. The Raspberry Pi schematics are available in PDF format, which is a good start and would also people to use the expansion headers (e.g. P1 provides access to GPIOs, SPI, I2C and UART interfaces) and create modules more easily. For the Raspberry Pi to come an open hardware platform, the schematics in .sbk format (so that they can be modified if needed),  Bill of materials,  Gerber files and PCB layout files (they laid out the board with Mentor Graphics Expedition) would have to be released, something which apparently they plan to do at a later stage. Once they do, it will be interesting to see […]

Emcraft Open Sources uCLinux and U-boot for Cortex M3 and M4 MCUs

Emcraft Systems has open sourced its ports of U-Boot and uClinux for Cortex-M3 and Cortex-M4 which are available on github at https://github.com/EmcraftSystems. This release supports the following platforms: ST Micro STM32F2 NXP LPC17XX Actel  SmartFusion Freescale Kinetis You can check the source code as follows: uCLinux: git clone git://github.com/EmcraftSystems/linux-emcraft.git U-boot: git clone git://github.com/EmcraftSystems/u-boot.git The company has also designed systems on module (SoM) with enough memory to run Linux with Cortex M3/M4 micro-controllers: Freescale Kinetis K70 SOM Actec SmartFusion SOM ST Micro STM32 SOM You might find more details on building/using u-boot or uClinux on EmCraft documentation page (especially linux-cortexm-um-1.4.1.pdf) and you may want to check EmCraft website for details on available hardware and BSP for Cortex M3/M4 solutions.

Building Chromium OS for Raspberry Pi (ARMv6)

I had previously written the instructions to build an older version of Chromium (via Berkelium) for ARM using Beagleboard/Overo rootfs in order to use it with Xibo digital signage. Recently I’ve been contacted by hexxeh, who maintains Chromium OS vanilla builds for x86 and MacOS computer, as he intends to provide Chromium OS for the Raspberry Pi, and you should be able to get a SD card image once everything is working from the site above. Today, I’ll post the steps followed to build Chromium OS LKGR (“the latest revision to pass only unit tests”) optimized for  ARMv6 processor with soft-float support, which is the type of processor (Broadcom BCM2835) used in the Raspberry Pi. Please note that although it can build, it still does not run properly and a few more changes are needed. First, you’ll need a fast machine to build Chromium OS in a reasonable amount of […]

Ubuntu on AllWinner A10 based Mele A1000 Set-top Box

I’ve recently received and reviewed the 70 USD Mele A1000 STB powered by AllWinner A10, but haven’t been able to hack it yet since I’ve have not received the USB to Serial cable necessary for debugging the board. However, somebody else (Tom Cubie) had time to hack the box and run Ubuntu from a SD card (while still keeping Android in the flash) as you can see below. This port does not seem to include hardware accelerated GUI just yet, but this is definitely a step in the right direction. Tom said he just followed the instructions at http://rhombus-tech.net/allwinner_a10/hacking_the_mele_a1000/ and http://rhombus-tech.net/a10_mmc_boot/ to have Ubuntu working, but those do not appear to be that clear at the moment.

Sunlike UMPC-1021: 85 USD AllWinner A10 Based 10.2″ Android 4.0 Netbook

Sunlike, a Shenzhen-based manufacturer, showcased their UMPC-1021 Android 4.0 netbook at the China sourcing fair last week. This netbook is powered by an AllWinner A10 (ARM Cortex A8) processor with 1GB RAM and 4GB flash and features a 10.2″ LCD display (but not a touchscreen), a 1.3MP front camera and a 2100mAh battery. Here are the specifications of Sunlike UMPC-1021 Android netbook. CPU AllWinner A10 @ 1.2 GHz Operation system Android 4.0 ICS or WinCE Memory 1G RAM Storage Device 2/4/8G NAND Flash LCD 10.2″ PANEL 16:9 wide screen. 1024×600 Resolution LAN 10/100M Ethernet WIFI 802.11b/g USB Port 3x USB 2.0 Host External Storage SD Card Slot Build-in camera 1.3 MPixel Audio Build-in stereo speaker Microphone Dimensions 280 x 189 x 25 mm Battery 7.4V 2100 mAh – 3 to 5 hours usage The company also explains that this netbook can be used for 5 hours with the “default” 2,100 mAh battery, but they can extend that to 10 hours with a 4,000 mAh battery.

Second Release of Debian 6 for Raspberry Pi

As Raspberry Pi boards have started to ship this week, the Raspberry Pi foundation has also posted a new Debian 6.0 “squeeze” release to the downloads section of raspberrypi.org this week-end. This release contains several performance enhancements, including enabling the 128K system L2 cache for the first time, and first-cut ALSA drivers. Enabling the L2 cache will boost the ARM CPU performance, however, it may decrease the GPU performance. So this setup is ideal for headless server, but for other applications, for example a media player decoding 1080p30 videos, the performance might actually go down. This is still customizable, as the L2 cache can be enabled / disabled with enable_l2cache parameter in the config.txt file stored on the SD card. The ALSA drivers are here for audio support, so audio output might not have been supported in the first release (TBC), except if they used another type of audio drivers […]
