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, […]

P2P for embedded systems: BitTorrent and Emule – Part 2

In part1, I explained how to build and install aMule for mips platorm, in part2, we’ll build and install Transmission BitTorrent client for devices based on Sigma Designs SMP8634/SMP8635. Transmission BT is already used in quite a few NAS and media players including Syabas Networked Media Tank, Western Digital WD MyBook, ReadyNAS, D-Link DNS-323 & CH3SNAS… as you can see at the bottom of the transmission download page. Building Transmission 2.13 daemon and client First download Transmission 2.13 source code and required dependencies: OpenSSL 1.0.0c, cURL 7.21.3 and libevent 1.4.14b (do not use libevent 2.0.x). You’ll also need zlib 1.2.5 that we compiled in part1. Extract them: tar xjvf ../Downloads/transmission-2.13.tar.bz2 tar xzvf ../Downloads/openssl-1.0.0c.tar.gz tar xjvf ../Downloads/curl-7.21.3.tar.bz2 tar xzvf ../Downloads/libevent-2.0.9-rc.tar.gz Build OpenSSL 1.0.0c: ./Configure no-asm –prefix=/home/jaufranc/edev/libs linux-generic32 make CC=”mipsel-linux-gcc” AR=”mipsel-linux-ar r” RANLIB=”mipsel-linux-ranlib” make install Build cURL 7.2.13: ./configure –prefix=/home/jaufranc/edev/libs –build=mipsel-linux –target=mipsel-linux -host=i686 –disable-ipv6 –without-random –with-ssl=/home/jaufranc/edev/libs –with-zlib=/home/jaufranc/edev/libs CC=mipsel-linux-gcc LDFLAGS=-ldl make make install […]

P2P for embedded systems: BitTorrent and Emule – Part 1

Whether your device is a Network Access Storage (NAS) or a media player with network capabilities, you may consider adding P2P to allow downloads of files as you would do on your computer. Two of the most used P2P protocols are BitTorrent and eMule, but most of the client have a UI designed for Linux or Windows and may not be easily ported to an embedded system. So what we need to look for here are command line based clients or daemons that can be compiled and run in an embedded platform. After some research, here are the 2 programs we’ll use: aMule 2.2.6 a multiplatform eMule-like client Transmission 2.13 running as a daemon for BT dowloads Today, I’ll show how to use aMule 2.2.6 in Sigma Designs SMP863X target, for example in Popcorn Hour A-100. But a similar method (just a different compiler mips-linux-gnu-gcc and setting Little endian (-EL)) […]

Near Field Communication (NFC) Introduction and Software Development

Android 2.3 features near field communication (NFC) in order to allow payment through your phone as it is already implemented in Japan with FeliCa (Felicity Card), a contactless RFID smart card system from Sony, direct communication between NFC devices, RFID reader, etc… NFC is already supported in Samsung / Google Nexus S. In this blog post, we’ll see what near field communication is, which hardware is needed and what needs to be done at the software level (driver and NFC stack). What is Near Field Communication ? Extract from Wikipedia: Near Field Communication or NFC, is a short-range high frequency wireless communication technology which enables the exchange of data between devices over about a 10 centimeter (around 4 inches) distance. The technology is a simple extension of the ISO/IEC 14443 proximity-card standard (proximity card, RFID) that combines the interface of a smartcard and a reader into a single device. An NFC […]
