Fernvale Open Source Hardware IoT Board Based on Mediatek MT6260 SoC with GSM Connectivity

Andrew Huang (Bunnie), an hardware engineer, known for hacking the original XBOX, and more recently for Novena open source laptop, has decided it could be interesting to reverse-engineer Mediatek MT6260 processor, as in China, it’s difficult to get documentation, SDK, and tools if you don’t commit to purchase X chips, where X is a rather large number. He and others also checked whether their work could be open sourced legally, and assert their “fair use” rights to reverse-engineer hardware and firmware. And so Fernvale project was born both as a technical challenge and to make a point. MT6260 is a $3 ARM7EJ-S processor clocked at 364 MHz with 8MB built-in RAM, interfaces such as I2C, SPI, PWM, UART, as well as LCD and touchscheen controller, and audio codec, battery charger, USB, Bluetooth, and GSM support, which make the $6 Atmel MCU used in Arduino board look expensive. The main differences […]

3D Graphics Acceleration in Linux on Allwinner A80 based Cubieboard4

Allwinner A80 is a powerful octa-core processor found in development boards and TV boxes such as Cubieboard4 or Tronsmart Draco AW80. Some early Ubuntu images and instructions had already been released for A80 Optimusboard and Draco AW80, but none of these featured GPU drivers for 3D acceleration, which to be honest, has limited advantages in Linux desktop distributions since desktop environments and most apps require full OpenGL support, i.e. not only OpenGL ES, and the only ARM SoC that can provide OpenGL support without external graphics card is Nvidia Tegra K1 SoC. Having said that GPU drivers would pave the way for smooth OpenELEC / Kodi user interface support in Allwinner A80 Linux distributions. That’s only one part of the puzzle, since the GPU normally handles the user interface, while the VPU takes care of video decoding. The good news is that CubieTech release updates images for their Cubieboard4 (CC-A80) […]

WeTek Play Giveaway with DVB-S2 or DVB-C/T/T2 Tuner

WeTek Play is dual core set-top box officially supporting Android 4.4 and OpenELEC 5.0, and with support for several other Android or Linux distributions. I’ve recently written an updated review of WeTek Play with the latest Android 4.4 firmware, and it’s a pretty good device to watch Live TV either from the Internet via WeCloud Antenna app with over 180 free-to-air channels, or from satellite, cable or terrestrial TV thanks to the DVB-S2 or DVB-C/T/T2 tuner included in the box. EPG, PVR and timeshifting functions are all working very well, except some display issues with Asian languages. The company proposed to give away two WeTek Play STB to CNX Software readers. My model comes with a DVB-S2 tuner, but winners will be able to chose either DVB-S2 or DVB-C/T/T2 tuner as per their preference. Here’s what you have to do to enter the contest, and some terms and conditions: To […]

OpenELEC 5.0 Linux Distribution Released with Kodi 14

OpenELEC (Open Embedded Linux Entertainment Center) is a lightweight Linux distribution aiming at turning your computer or device into a Kodi media center. So instead of installing Kodi as a program or app on a desktop OS or Android, you could have a dedicated machine, which boots faster, has lower requirements (90-125 MB required for a full installation), and supported external tuners to watch live TV, as well as PVR & timeshifting functions out of the box. The developers have now announced OpenELEC 5.0 release, the successor of OpenELEC 4.2. Key changes for OpenELEC 5.0 include: Update from XBMC 13 (Gotham) to Kodi 14 (Helix) Update from Linux 3.16 to Linux 3.17 Switch from OpenSSL to LibreSSL Freescale i.IMX6 support for SolidRun CuBox-i, CuboxTV, and Hummingboard AppleTV support has been discontinued Beside build for the CuBox devices, OpenELEC 5.0 can be downloaded for x86 (32- and 64-bit builds), and the […]

Iliad’s Online Labs Offers Quad Core ARMv7 Dedicated Servers

Iliad (Free) is a French company known to bring the price of technology down for the masses. Several years ago, they disrupted the Internet broadband market, by bringing low cost triple play broadband services to market, and more recently they entered the mobile market with 2 Euros 3G/4G monthly subscriptions. The company also owns Online.net providing hosting services, and which has recently launched a public preview for Online Labs cloud platform. Most hosted solutions nowadays relies on x86 servers and virtualization, but Online Labs instead features dedicated physical ARM servers connected to SSDs. The company call their custom-made credit-card size server modules C1 boards, completely unrelated to ODROID-C1 boards, as those are powered by a quad core ARMv7 Marvell processor with 2GB RAM, and a 1Gb/s network interfaces. These are then assembled into racks as shown below. And finally 16 racks are inserted into a chassis with a control board, […]

Snail Games OBox is an Upcoming High End Android Game Console Powered by Nvidia Tegra K1 Processor

Snail Games is a gaming company based in Suzhou, China, with a branch in the US, specializing online games with over 85 million account on sites like woniu.com for the Chinese market, and playsnail.com for the North American market. Snail is now planning to launch an Android 4.4 console called OBox Online at CES 2015. Internally, the gaming console is comprised of a motherboard, a processor board, an HDD board, and an optional multi-media board. Two processor board are currently available with variants of Nvidia Tegra K1 quad core 32-bit processor, and I assume it should be possible to upgrade the console with a more powerful processor and more memory in the future. Technical specifications listed in a leaked/released PDF: Processor Board SoC Option 1 – Nvidia Tegra K1 TD570D quad-core ARM Cortex A15 CPU @ 2.0 GHz, and Kepler GPU with 192 CUDA cores Option 2 – Nvidia Tegra […]

LA1016, LA2016, and LA5016 Logic Analyzers Cost as Low as $75

I remember 10+ years ago, when my managers argued whether buying a logic analyzer, because some of its functions could be done by an oscilloscope, and logic analyzers were selling for a few thousands dollars at the time. Fast forward to 2014, it’s now possible to acquire lower end logic analyzers that connect to a PC for as low as $75 thanks to products such as LA1016, LA2016, and LA5016, all supports 16-channels and respectively 100, 200 and 500 Mbps sampling rate. Key features and specifications: Input channels – 16 Max Sampling Rate: LA1016: 100M; LA2016: 200M; LA5026: 500M Measurement Bandwidth – LA1016: 20M; LA2016: 40M; LA5016: 80M Min pulse width – LA1016: 20ns; LA2016: 12.5ns; LA5016: 6.25ns Hardware memory size – LA1016/LA2016: 1Gbits; LA5016: 512Mbits Hardware sampling depth – LA1016/LA2016: 50M/channel; LA5016: 32M/channel Max compressed depth – LA1016/LA2016: 10G/channel; LA5016: 5G/channel Input voltage range – -50V ~ +50V Input […]
