Yet another Android 4.0 demo on a development platform. This time, Android 4.0.1 runs on a Jaguar Tablet powered by Ziilabs ZMS-20 ARM Cortex A9 processor. It runs pretty smoothly. 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 starting to write daily news, and reviews full time later in 2011. www.cnx-software.com
ARM announced a free version of its Eclipse-based DS-5 tools for small development firms (with 10 or fewer developers) and individuals who publish applications for Android. The ARM Development Studio 5 (DS-5) Community Edition (CE) helps create performance- and power-optimized native software by integrating a graphical debugger for code generated for the Android Native Development Kit (NDK) and a basic version of the ARM Streamline performance analysis tool. DS-5 CE is designed to work with Android Virtual Devices ( AVDs), development boards and devices that run Android 2.2 and API 8 or higher. ARM Development Studio 5 (DS-5) Community Edition is distributed as plug-in for Eclipse and completes the app developer toolkit with a C, C++ and Assembly graphical debugger that builds on the Android Debug Bridge (ADB), a software performance profiler and system analyzer (ARM Streamline). To get started, you’ll need Eclipse IDE, the Android SDK and the Android NDK […]
Rockchip has announced Android 4.0.1 (ICS) would be ready by the first week of December with Rochchip RK2918 based tablets shipping with the new OS available later in December. The company claims this will be the first Android 4.0 tablet available in the market. That also means that owners of Archos Arnova G2 tablets should be able to run Android 4.0 very soon. The demo below seems relatively smooth compared to other demos I have seen on development boards such as ST Ericsson Snowball, so I suppose Rockchip has already enabled hardware acceleration.

Android 4.0.1 can now run on ST Ericsson Nova A9500 low cost development board “snowball”. The build is available at https://android-build.linaro.org/builds/~linaro-android/staging-snowball/. You can Android 4 (ICS) it in action in the Snowball board in the video build using build number 84. This is a bit sluggish since Android 4 currently lacks hardware acceleration on this development board but Linaro and the igloocommunity will implement it in the next few weeks. If you have an ST Ericsson snowball board, here are the instructions to try the latest Android 4.0 build for the platform: Get the images: wget –no-check-certificate https://android-build.linaro.org/jenkins/job/linaro-android_staging-snowball/lastSuccessfulBuild/artifact/build/out/target/product/snowball/boot.tar.bz2 wget –no-check-certificate https://android-build.linaro.org/jenkins/job/linaro-android_staging-snowball/lastSuccessfulBuild/artifact/build/out/target/product/snowball/system.tar.bz2 wget –no-check-certificate https://android-build.linaro.org/jenkins/job/linaro-android_staging-snowball/lastSuccessfulBuild/artifact/build/out/target/product/snowball/userdata.tar.bz2 Get the linaro-image-tools and create the image: bzr branch lp:linaro-image-tools ./linaro-image-tools/linaro-android-media-create –mmc /dev/sdc –dev snowball_sd –system system.tar.bz2 –userdata userdata.tar.bz2 –boot boot.tar.bz2 MINICOM settings: minicom -D /dev/ttyUSB0 -w -C minicom.txt You must setup the boot args as follows: U8500 $ setenv loadbootscript fat load mmc 1:1 ${loadaddr} […]
Romotive startup has designed “Romo”, a tank-like Robot controlled by Android or/and iOS mobile devices. Peter Seid and Phu Nguyen – Romotive’s co-founders – have raised over 114,000 USD on KickStarter website from more than 1,100 contributors looking to buy the Romo robot. The company has reached its founding target (32,000 USD) and can now move forward on production. You can still get the Robot for 78 USD (+12 USD shipping if you live outside the US) on KickStarter. You’ll need two Android or iOS devices to play with it: one acting as a camera that sits on the “Romo” and the other to control the robot’s movements and receive the camera stream via Wi-Fi. The motors are interestingly controlled by audio signals coming from the smartphone. Romo’s Hardware is composed of the following: A motorized, acrylic base with an accessory port that can be controlled by any smartphone (or […]
Sola has written the instructions (in Japanese) to build Android 4.0 (ICS) for Beagleboard and Beagleboard-xM.

Paul O’Brien, founder of modaco, has created a custom kernel with CIFS/SAMBA support, USB drive and keyboard / mouse support for Galaxy Nexus smartphone running Android 4.0 (ICS). This is a temporary download until MCR (MoDaCo Custom ROM) is released. This should be flashed via ‘fastboot flash boot boot.mck.img’ to a device with an unlocked bootloader. This is designed for devices running the I9250XXKK1 / ITL41D (android-4.0.1_r1) ROM.
