Cross-compiling Python for MIPS and ARM Platforms

Python programming language is used in several open source projects such as Sugar OS and Xibo. Let’s see if we can cross-compile it in Ubuntu 10.10 using a mips compiler. I’ll use the instructions given at http://randomsplat.com/id5-cross-compiling-python-for-embedded-linux.html. Let’s download Python 2.7.1 first and extract the source code:

Then run the following command in Python-2.7.1 in order to build some tools for the host:

There is no patch for Python 2.7.1 cross-compilation in the link above, so let’s just try to configure and build it:

If we don’t use a patch the first error is:

So I used some older patch to create a new patch: http://www.cnx-software.com/patch/python-2.7.1-cross-compile.patch. You can download it an apply it as follows:

And repeat the step above to configure and cross-compile Python for mips. Finally install Python in ~/Python-2.7.1/install for example:

After that copy all necessary files in ~/Python-2.7.1/install to your […]

Ayuda Splash Digital Signage Player Becomes Open Source

Ayuda Media Systems announced OpenSplash – a free, open source digital signage player at ISE 2011. Press Release Excerpt: Ayuda Media Systems (“Ayuda”) announced today at ISE 2011 that it will be open sourcing its Splash Digital Player. Dubbed “OpenSplash”, it is a free, multi-platform open source player that can be driven by any content management and scheduling system. “Offering a free, open source media player will enable a new wave of innovation in the signage industry” said Andreas Soupliotis, President & CEO of Ayuda. “There are a multitude of software vendors in the space that basically all do the same thing – push content from a content management system (CMS) to a network of players. Some do it a little better than others but the differentiation of identity is just not there. If there were a standard open software player that the industry rallied behind then everyone could focus […]

Resources for Atmel AT91SAM9: SAM926X, SAM9GXX, SAM9M1X, SAM9XE…

Atmel AT91SAM9 – or simply Atmel SAM9 – series are versatile microcontrollers and embedded microprocessors used in variety of products such as internet radios, embedded p2p downloaders, smart grid in-home displays, and much more.

SAM9M eMPU based on ARM926EJ-S clocked at 400Mhz and with a video decoder: AT91SAM9M10 and AT91SAM9M11 SAM9R MCU based on ARM926EJ-S running at 210 Mhz with similar characteristic as the original SAM9 MCU, except it does not support USB Host but can be used as a High Speed USB device: AT91SAM9R64 and AT91SAM9RL64 SAM9XE MCU are also based on ARM926EJ-S running […]

Nufront ARM Cortex-A9 Laptop running Ubuntu at CES 2011

Nufront (新岸线) showcased their minipc based on Nusmart 2816 at Techcon 2010, they are now back at CES 2011 to show off their laptop reference designs. They provide two laptop designs with 10″ and a 14″ displays. The mother board is the same for both devices, only the casing changes to accommodate the display. The laptops runs Ubuntu and Android 2.2. They will also support some undisclosed operating system(s) later on (It should be Windows 8 and/or Chrome OS).  The processor is a dual core Cortex A9 running at 2GHz, so I suppose this is the Nusmart 2816. The laptop will have 1 or 2 GB RAM depending on the configuration. Nufront said those laptops should be available within 6 months. No indication of price has been given. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and […]

Third Generation OLPC XO Laptop powered by ARM Marvell Armada 610

OLPC (One Laptop Per Child) was also at CES 2011 in Marvell stand with their third generation OLPC XO laptop named OLPC XO-1.75, after the first generation using AMD and the second Via Technologies. Charbax interviewed Ed NcNierney, Chief Technology Office at OLPC. They only changed the PCB in this version, i.e. the casing, keyboard, monitor is the same as the previous generations.The processor used in OLPC XO-1.75 is the ARM based Marvell Armada 610 (single core) running at 1GHz with 1GB RAM and 4GB Flash. The laptop can be recharged with a hand crane for 1 minute, then the laptop can be used for 10 minutes (color) and about 12 minutes (black and white). With the third generation, the price is only marginally cheaper than the previous generation (<200 USD), but the power consumption is now 2 Watt (instead of 4 Watt) and it is the most important part, […]

3D Capable Android Tablet: iStation Zood (Z3D)

iStation, a south korean company, announced the iStation Zood (codenamed Z3D) one the first (if not the first) stereoscopic 3D capable Android Tablet. You’ll need 3D content and wear polarised 3D glasses to take advantage of it. It features a 7″ multi-touch capacitive touchscreen and is powered by a Telechips ARM11 core processor (TCC8900?) running Android 2.1. The performance does not seem that great, but it’s still usable and being based on Telechips the price should be relatively low. Here are the Zood specifications on iStation website: Real 3D panel 7″ TFT-LCD (WVGA, 800×480) Capacitive touchscreen 16/32 Nand flash Acceleration sensor Wifi 802.11 b/g/n Bluetooth v2.1 + EDR FM Radio USB 2.0 Host and Slave SDHC card reader HDMI output Android 2.1 In the video below (but not in the specs?), they say this tablet also supports digital terrestrial television (DTT), now only supporting T-DMB, the standard used in south […]
