You have most probably heard of Lima, an initiative to provide fully open source Mali-200 & Mali-400 drivers by reverse-engineering the closed source Mali GPU drivers. A separate effort, Etnaviv Project, has now started to offer open source drivers for Vivante GCxxx GPU used in SoC such as Marvell Armada 1500 (notably used in mainly Google TV platforms), Rockchip RK2918 (present in many older tablets), Freescale i.MX6 (used in newer tablets, low cost development boards, some SoMs and GK802/Hi802 mini PCs). The project is called Etnaviv. The introduction of Etnaviv Project reads as follows on the corresponding Github account: Project Etnaviv is an attempt to make an open source user-space driver for the Vivante GCxxx series of embedded GPUs. The current state of the project is experimental. It is currently only of use to developers interested in helping develop open source drivers for the hardware, reverse engineering, or in interfacing […]
$159 CuBox Pro: Open Source Development Platform Based on Marvell ARMADA SoC
Back in 2011, SolidRun unveiled the CuBox, a miniature open source development platform based on Marvell Armada 510 SoC (88AP510) and aimed at applications such as multimedia, set-top-box, network attached storage (NAS), thin client, digital signage, automation… SolidRun has now announced an upgraded version called CuBox Pro based on the same platform but with 2 GB RAM, and a redesigned casing.

3.95 Euros RPI-UEXT Breadboard & UEXT Adapter for Raspberry Pi is Now Available
Last month, I wrote about an upcoming T-shaped adapter for the Raspberry Pi that can easily plug into a breadboard, and provides a UEXT connector that can bring new features (RTC, GPRS, sensors, relays…) to the Raspberry Pi via low cost external UEXT modules. Olimex has just announced the RPI-UEXT adapter is now available for 3.95 Euros. To connect RPI-UEXT adapter to the Raspberry Pi, you’ll need to purchase a 26-pin ribbon cable and a breadboard if you don’t have these already. Olimex provides those 2 for respectively 2 & 2.95 Euros. That means a complete set would cost 8.90 Euros. As discussed on my first RPI-UEXT post, what makes this little board really interesting are all the existing UEXT modules (over 20) that bring new features at very low cost. Olimex uploaded a video showing the Raspberry Pi, the RPI-UEXT and the MOD-IO UEXT module connected together, with the Raspberry […]
Build Your Own Freescale i.MX6 Quad Laptop
Andrew Huang (“Bunnie”) and others have been working on an open source laptop based on Freescale i.MX6 Quad processor since June, and they’ve recently got the motherboard. Beside featuring a powerful quad core ARM processor, the design files are also provided, so if you have the right skills and resources you can build it yourself. The open source laptop mainboard (Codename: Novena) has the following specifications: SoC – Freescale iMX6 Quad @ 1.2GHz with Vivante GC2000 GPU System Memory – 64-bit DDR3-1066 SO-DIMM, upgradable to 4GB Storage – microSD boot flash, SATA-II connector for hard drive / SSD, SD card reader and serial EEPROM (for storing crash logs and other bits of handy data). FPGA – Spartan-6 CSG324. It has several interfaces to the CPU, including a 2Gbit/s RAM-like bus. Internal ports & sensors: mini PCI-express slot UIM slot for mPCIx mobile data cards Dual-channel LVDS LCD connector (up to […]
Open Hardware System on Module Project
“JM” has started working on a system-on-module project with the goal “to create a whole range of SoM boards and motherboards that can handle a large number of embedded projects”. He has just released schematics and layout files created with Kicad for a dual NXP LPC1764 SO-DIMM module and the baseboard under GPL3 license. The next goal is to release an AllWinner A10 SoM and corresponding baseboard. Kicad is an open source schematics capture and PCB layout software that can run in Windows, Linux and Mac. If you want to read the schematics or try it out, you can freely download it. In Ubuntu you could just use apt-get:
1 |
sudo apt-get install kicad fped |
The hardware files for the module and carrier board are available here. JM explains that the LPC module and baseboard have already been manufactured and tested, so it could just be a matter of adapting the module for AllWinner A10/A20. […]

Le Labo Citoyen Gasser – Raspberry Pi Based High Precision Pollution Monitoring System
“Le Labo Citoyen” is a recently founded French non-profit organization aimed at “promoting and experimenting with innovating and free technologies for the citizens and the environment”. Their first project is to gather pollution data (NO2, O3, and SO2 levels) in Paris using 2 (soon to be) open source components: Gasser – Self-contained mobile sensor currently powered by the Raspberry Pi ThingStream – Open source IoT datastore which should be similar to iDigi Cloud, except you can just store data in your own server or on “Le Labo Citoyen” servers. Gasser has four main parts: Sensor(s) – Alphasense B4-series sensors (black and red component in the top left of the main box) with accuracy of up to <10 ppb (parts-per-billion). Cost: ~110 Euros. They currently only use the NO2 (nitrogen dioxide) sensor. ADC & Computer – Raspberry Pi (Cost: ~30 Euros) & Delta-Sigma ADC (Cost: ~30 Euros). Communication Medium – Huawei […]
