15 USD ARM Cortex A8 Linux Computer by Rhombus Tech

Many of you already probably know the Raspberry Pi Foundation 25 USD ARM Linux Computer. Rhombus Tech, another non-profit organization, is planning to design a 15 USD ARM Linux computer (excluding casing, power supply, shipping, VAT and custom duties) that the company claims would be at least 3 times faster that the Raspberry Pi. This computer would be an EOMA-PCMCIA CPU card powered by an Allwinner A10 ARM Cortex A8 CPU clocked at 1.5ghz. Here are the (expected) specifications of this board: Approximately Credit-card size format (56mm x 90mm) An Allwinner A10, 1.5ghz ARM Cortex A8 1GB of RAM At least 1gb of NAND Flash (possibly up to 16gb) Operation as a stand-alone computer (USB-OTG powered) 2160p (double 1080p) Video playback MALI 400MP 3D Graphics, OpenGL ES 2.0 compliant. HDMI, Micro-SD, Headphones Socket, EOMA-PCMCIA-compliant interfaces (RGB/TTL, I2C, USB2, SATA-II, 10/100 Eth) Expansion Header (similar to Beagleboard, IMX53QSB, Origen etc.) With this […]

Android 4.0 Source Code For MIPS is Now Available

In the last few weeks, MIPS has already released the Linux Kernel for MIPS Android and shown us a low cost (99 USD) Android ICS Tablet. Today, they announced the official release of MIPS Android 4.0 source code. The latest version of Android 4.0 is “mr0″ and you can read the release notes for further details. Before downloading the Android source code be sure that you have a correctly setup Linux workstation. Now, here are the instructions to checkout MIPS Android 4.0:

mkdir mipsandroid
cd mipsandroid
repo init --repo-url=git://github.com/MIPS/repo.git --repo-branch=stable -u git://github.com/MIPS/manifests.git -b mips-ics-mr0 -m mips-ics-4.0.1_r1m1.xml
repo sync

mkdir mipsandroid

cd mipsandroid

repo init --repo-url=git://github.com/MIPS/repo.git --repo-branch=stable -u git://github.com/MIPS/manifests.git -b mips-ics-mr0 -m mips-ics-4.0.1_r1m1.xml

repo sync

The first time you run the repo sync it will download several gigabytes of source code to your machine so be patient and it may take a few hours. Once the download is completed future updates may take only a few minutes since only the code changes are downloaded. If you just want to have a look, All MIPS Android source code can also be viewed online at http://www.github.com/mips. […]

Android Training & Tutorials

The Android team just announced the launch of Android Training a collection of classes aimed at helping developers to build better Android applications. Each class explains the steps required to solve a problem, or implement a feature, with code snippets and sample code. They’ll add more materials over time, but right now developers can already learn (more) about the following topics: Designing for Multiple Screens Improving Layout Performance Managing Audio Playback Optimizing Battery Life Remembering Users Sharing Content Capturing Photos Maintaining Multiple APKs Developing for Enterprise Monetizing Your App Designing Effective Navigation There are currently 34 lessons on all those topics, and most include code samples such as the News Reader (Designing for Multiple Screens). You can get started immediately by visiting Android Training page.

Android 4.0 Hardware Graphics Acceleration Coming to More Platforms

The Linaro Android Platform Team has just posted a weekly update to their progress. They are going to release 11.12 very soon with hardware graphics acceleration to 2 of their members development boards: ST Ericsson Nova A9500 Snowball and Samsung Exynos 4212 Origen boards. So if you have any boards or products based on those processors you should be able to get an hardware optimized version very soon. Hardware acceleration is already available on all OMAP4 platform such as Pandaboard, since this was the default Android ICS target. They also introduced support for the ARM DS-5 debugger, an Eclipse plug-in to help developer create high performance performance and low power 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. Here’s a list of this week achievements: Key Points for wider discussion […]

Build the bootloaders (U-boot & X-Loader) for Pandaboard

I’ve tried to compile u-boot and x-loader for Pandaboard by following the instructions given at http://omappedia.org/wiki/Get_started_with_ubuntu_on_omap4#Bootloaders. I did this in Ubuntu 10.04 LTS with Linaro gcc compiler. Here are the instructions for the build: Create the folders:

mkdir bootloader
cd bootloader

1 2	mkdir bootloader cd bootloader

Get u-boot and checkout the omap4_dev branch:

git clone git://git.omapzoom.org/repo/u-boot.git
cd u-boot
git checkout L24.9

git clone git://git.omapzoom.org/repo/u-boot.git

cd u-boot

git checkout L24.9

You may use a different tag. Simply run “git tag -l | grep L24” to see the list of tags. (I used the latest at the time of this post). Build u-boot for OMAP4

make ARCH=arm distclean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-

make ARCH=arm distclean

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-

At this point, you should get U-boot (u-boot.bin). get x-loader and checkout the omap4_dev branch:

cd ..
git clone git://git.omapzoom.org/repo/x-loader.git
cd x-loader
git checkout L24.9

cd ..

git clone git://git.omapzoom.org/repo/x-loader.git

cd x-loader

git checkout L24.9

N.B: Both u-boot and x-loader folders must be at the same directory level. build x-loader for OMAP4:

make ARCH=arm distclean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- ift

make ARCH=arm distclean

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- ift

The x-loader (MLO) should now be ready. Finally, you simply need to copy MLO and u-boot.bin files to the SD card. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting […]
