Olimex Offers Up to 50% Discount on OLinuXino Boards to Open Source Developers

Olimex has been providing low cost MCU devkits for many years, and this year they started offering more powerful embedded Linux development boards called OLinuXino. The first family (iMX233-OLinuXino) is based on Freescale i.MX233 ARM9 processor @ 454 Mhz and comes in three form factor: iMX233-OLINUXINO-MAXI – 2x USB host, Ethernet, TV-out, GPIOs, SD-CARD, Audio-In, Audio-Out, UEXT – 44.95 Euros. iMX233-OLINUXINO-MINI – 3x USB host, TV-out, GPIOs, SD-CARD, Audio-In, Audio-Out, UEXT – 34.95 Euros iMX233-OLINUXINO-MICRO – USB host, TV-out, GPIOs, SD-CARD, ready for breadboaring – 23.95 Euros They are also working on A13-OLinuXino board featuring AllWinner A13 Cortex A8 processor. To promote their new boards (and reward open source developers – cf comment below), the company company has decided to offer discount to open source developers. The way I understand it: you need to buy a board first, publish the source code somewhere and write about it on your own […]

Equiso Smart TV: 69 USD Android mini PC with Wireless Remote

Here’s yet another Android mini PC HDMI Stick. Equiso has started a KickStarter compaign to raise funds to complete development and manufacture the Equiso Smart TV, an Android mini PC based on Telechips TCC8925 Cortex A5 processor. It looks very similar to CX-01 mini PC with Android 4.0 running on a TCC8925 processor, 512 MB RAM and the lack of a microSD card slot. The only hardware differences are that it includes 8GB internal storage (vs 4GB for CX-01), and it features an HDMI 1.4 port (vs 1.3 for others). Here are the specs of the device: Telechips TCC8925 Arm Cortex A5 Processor @ 1GHz + Mali 400 3D Graphics Processor 512 MB DDR3 RAM 802.11 N wireless radio 8 GB Memory Internal (WiFi) 1.4 HDMI Plug n’ Play Interface, 3D, ESD protection, CEC USB 2.0 port microUSB 2.0 port to power the device Dimensions – 80mm x 30mm x […]

Quick Binary Debugging in Linux with Strace System Call Tracer

I’ve recently come across strace, a debugging utility for Linux that “monitor the system calls used by a program and all the signals”. It may not be that useful if you have the source code and can run other debugging tools such as gdb, or simply add printf to your code. But if you don’t have source code of the program, or you are a system administrator who wants to check if the program fails due to file access reasons, for example, this is really a great tool as it may help you find out which file causes problem. In my case, I was trying OpenGL ES on an ARM platform, and at least part of the code comes in libraries that are only available in binary form. I got the following error message running es2_info (part of mesa-utils-extra): UMP: ump_arch_open() failed to open UMP device driver ********************************************************************* ERROR: In […]

Rikomagic MK802 II Mini PC Will Be Available in September

Rikomagic announced that they are working on two new versions of the MK802 Android mini PC. The first version (MK802 II) will be based on basically the same hardware (AllWinner A10 SoC), but with a different casing, an HDMI male connector, and 3 USB connectors (2 microUSB and 1 standard USB). They will apparently add some holes to the casing for better ventilation in order to decrease excessive heat. The company also mentioned they are working on a version with a dual core processor without giving further details. If we want to play guessing games, it could be next generation AllWinner dual core Cortex A9 processor (codenamed sun6i), or a low cost dual core Cortex A5 processor such as TCC8925.

Toradex Releases Apalis Computer on Module Architecture Specification

Last month, Toradex released the preliminary specification for Apalis, a Computer on Module (CoM) architecture. Although the Apalis specification has been initially designed with ARM based processors in mind such as the Nvidia Tegra, Freescale i.MX and Texas Instruments OMAP processor families, it aims at being device and chip architecture independent. The Apallis specification defines the following: Interface Specifications: Signal Naming Convention – Rules to name pins (e.g. VCC, PWM1, PWM2, ) which are used for all modules. Signal Definition – Details about the pins named above Physical Pin Definition and Location Mechanical Specifications: Mounting and Fixation Module Size – Standard: 82 x 45mm | Extended: 82 x 56mm Pin Numbering – There is a total of 321 pin numbers (but a few less actually pins) Electrical Specifications: Power Supplies Power Control Back Feed Protection This specifications also defines mounting mechanisms for active cooling (e.g. heat spreaders) in case those […]

Android Transporter Enables WiFi Display Mirroring (similar to Miracast) of Android Devices

E.S.R.Labs is a German embedded software company mainly working for the automotive industry. But this time, they’ve started to work for the consumer market with Android Transformer, a software solution that can mirror an Android display to another Android device display via Wi-Fi in a similar fashion to what WiFi Miracast will do. Eventually, the company plan to make Android Transporter compatible with Wi-Fi Miracast, but in the meantime they rolled out their own solution by taking advantage of H.264 hardware encoders and decoders on Galaxy Nexus S and the Raspberry Pi. If they use standard APIs, I assume any hardware running Android that with H.264 hardware encode/decode should support their platform. I hope it will be work on (or be ported to) CX-01 mini PC which can be bought as low as $40 inc. shipping. It would make an even cheaper hardware than the Raspberry Pi (Up to 33% […]

Mozilla Renames Boot 2 Gecko to Firefox OS and Partners with ZTE & TCL

Mozilla announced it would rename its Boot 2 Gecko (B2G) HTML5 mobile operating system to Firefox OS, and that ZTE and TCL (under the Alcatel brand) would manufacture the first devices running Firefox OS using Qualcomm Snapdragon Processors. The first devices should be available early 2013, at first in Brazil through Vivo, Telefónica’s commercial brand. The company also said that telecom operators such as Deutsche Telekom, Etisalat, Smart, Sprint, Telecom Italia, Telefónica and Telenor are planning to sell Firefox OS based smartphones. The platform is said to be optimized for entry-level smartphones thanks to the removal of unnecessary middleware layers among other things. This should allow mobile operators to provide low-cost handsets with “richer experiences” for the developing markets. Firefox OS will be fully open source and the reference implementation of the required Web APIs is being submitted to W3C for standardization. Internally, the project still appears to be referred to […]

Use GNU Parallel to Speed Up Script Execution on Multiple Cores and/or Machines

I attended BarCamp Chiang Mai 5 last week-end, and a lot of sessions were related to project management, business apps and web development, but there were also a few embedded systems related sessions dealing with subjects such as Arduino (Showing how to blink an LED…) and IOIO board for Android, as well as some Linux related sessions. The most useful talk I attended was about “GNU Parallel”, a command line tool that can dramatically speed up time-consuming tasks that can be executed in parallel, by spreading tasks across multiple cores and/or local machines on a LAN. This session was presented by the developer himself (Ole Tange). This tool is used for intensive data processing tasks such as DNA sequencing analysis (Bioinformatics), but it might be possible to find a way to use GNU Parallel to shorten the time it takes to build binaries. Make is already doing a good job at […]
