Embedded Systems Conference 2015 Schedule – May 6-7, 2015

The Embedded Systems Conference took the name “Design West” for a couple of years, but this year, there’s no mention of Design West, and the Embedded System Conference 2015 will take place in Boston, MA, US on May 6-7, 2015. The 2-day event will have a demo hall, and well as sessions divided into 8 tracks: Connected Devices and the IoT Embedded Software Design Hardware: Design, I/O and Interfacing Prototyping Embedded Systems Design Software: Design, Languages, & Quality Fantastical Theater Teardowns The full schedule has now been posted, and I’ll build a virtual schedule with some of the sessions provided. Wednesday May 6, 2015 8:00 – 8:45 – Understanding Google/Nest Thread by Michael Anderson, Chief Scientist, The PTR Group, Inc. The IoT will live or die based on its connectivity. In examining existing wireless protocols, Google/Nest found most of them lacking. In order to address the needs for low-power wireless […]

Android 4.4 Source Code Released for ODROID-C1 Board

ODROID-C1 development board was launched on December 10, 2014, and a few days later U-boot and Linux source code was released for this low cost Amlogic S805 board, but Android was only due later due to licensing issues. I’ve just noticed Hardkernel uploaded Android 4.4 source code to github at the end of February. The build instructions are provided on ODROID-C1 wiki, and there are quite straightforward. You’ll need to type four command lines to get the code in a working directory:

mkdir odroid-c1
cd odroid-c1
repo init -u https://github.com/hardkernel/android.git -b s805_4.4.2_master
repo sync

mkdir odroid-c1

cd odroid-c1

repo init -u https://github.com/hardkernel/android.git -b s805_4.4.2_master

repo sync

and three more to build an Android image:

source build/envsetup.sh
lunch odroidc-eng
make -j8

source build/envsetup.sh

lunch odroidc-eng

make -j8

All relevant binary files (system, userdata, bootloader, kernel…) will be located in out/target/product/odroidc/ directory, and can be flash to your board via fastboot. Alternatvely, you can create an Android SD card image (out/target/product/odroidc/selfinstall-odroidc.bin) with:

make selfinstall

1	make selfinstall

That means developers will be able to easily customize source code for ODROID-C1 board, but they should also be able use this base […]

FOSDEM 2015 Schedule – January 31 – February 1 2015

FOSDEM (Free and Open Source Software Developers’ European Meeting) takes place every year during the first week-end of February. This year the developer-oriented event expects to bring over 5000 geeks to share ideas and collaborate on open source projects. Contrary to most other events, it’s free to attend, and you don’t even need to register, just show up. FOSDEM 2015 will take place on January 31- February 1 in Brussels. There will be 551 sessions divided into 5 keynotes, 40 lightning talks, 6 certification exams, and with the bulk being developer rooms and main tracks, divided into 7 main tracks this year: Languages, Performance, Time, Typesetting, Hardware, Security and Miscellaneous. I’m not going to attend, but it’s still interested to see what will be talked about, and I’ve concocted my own little virtual program out of the main tracks and developers’ rooms. There’s a few minutes overlap between some talks […]

How to Install Ubuntu ARM64 on Nexus 9 Tablet

HTC Nexus 9 is one of the first 64-bit ARM platform with powerful ARMv8 cores (e.g. not Cortex A53) that both commercially available, and relatively affordable at $399 to $599, at least significantly cheaper than the server boards such as Applied Micro X-C1. The tablet comes with Android 5.0 Lollipop, but for those of you who wish to have an ARM64 platform running Ubuntu or other 64-bit Linux operating systems, Ubuntu installation instructions provided by Ryan Houdek, Dolphin emulator developer, might come handy, especially it won’t affect your Android installation provided you have already unlocked your bootloader. The instructions are fairly long so I won’t reproduce them all here, so I recommend you check the detailed instructions on XDA, but the short summary below may give an idea of the amount of work needed: Install dependencies such as Aarch64 toolchain:

sudo apt-get install gcc g++ git gcc-4.9-aarch64-linux-gnu g++-4.9-aarch64-linux-gnu

1	sudo apt-get install gcc g++ git gcc-4.9-aarch64-linux-gnu g++-4.9-aarch64-linux-gnu

Build a initramfs with buildroot. You’ll need to enable […]

TyGL OpenGL ES 2.0 Backend for WebKit Speeds Up Web Rendering by Up to 11 Times

ARM, Szeged University in Hungary, and Samsung Research UK have been working on TyGL, a new backend for WebKit accelerated with OpenGL ES2.0, and developed and tested on ARM Mali-T628 GPU found in Samsung ARM Chromebook. It will typically provide 1.5 to 4.5 times higher performance, but in the best cases, it can achieve up to eleven times the performance of a CPU-only rendered page. The key features of TyGL include: Web rendering accelerated by GPU – Batching of draw calls delivers better results on GPUs. TyGL groups commands together to avoid frequent state changes while calling the Graphics Context API. Automatic shader generation – TyGL generates complex shaders from multiple shader fragments, and ensures the batches fit into the shader cache of the GPU. Trapezoid based path rendering – Work in progress. It will leverage GPU capabilities such as the Pixel Local Storage extension for OpenGL ES. No software […]
