Raxda Rock Development Board Unboxing, Quick Start Guide, and Benchmarks

Radxa Rock is an Android & Linux development board based on Rockchip RK3188 with 2GB RAM, 8GB NAND Flash, several I/Os that’s been available in beta version to a small number of developers in September 2013, with general availability starting at the very end of December 2013. Radxa team has sent me a board for me to try out. I’ll start with some unboxing pictures, write a Quick Start Guide for the first boot with Android 4.2.2, and run some benchmarks on the board. In another post, I’ll try some of the instructions to build Android and Ubuntu for the platform. Radxa Rock Unboxing Pictures & Video I’ve received the board in the following package via Fedex. Beside the board, we’ve got a Wi-Fi antenna, a USB power cable, and a plastic casing. Checkout Radxa Rock unboxing video below, if you want to find out exactly what’s you get when […]

Embedded Linux Conference Europe 2013 Schedule – Build Systems, Security, Device Tree, Debugging & Profiling Techniques, and More

Embedded Linux Conference Europe 2013 will conveniently start right after LinuxCon 2013, last 2 days (October 23-24), and take place at the same location: the Edinburgh International Conference Center, Edinburgh, United Kingdom. The Linux Foundation has published the schedule for the conference, so I’ll make my own virtual schedule with sessions that I find particularly interesting. Thursday – 24th of October 9:30 – 10:10 – Timeline For Embedded Linux by Chris Simmonds, Consultant, 2net Limited Today, Linux is woven into the fabric of our technology. Things such as printers, routers, TVs and phones all have their own “Inner Penguin”. Yet it was never originally intended to be used beyond desktop and server PCs. A lot of things had to happen before Linux could break out of the PC environment and make its way in the world as a jobbing jack-of-all-trades. Since the early beginnings of embedded Linux in the late 1990’s many people have contributed […]

ARM TechCon 2013 Schedule – ARM Servers, Internet of Things, Multicore, Hardware and Software Optimization and More

ARM Technology Conference (TechCon) 2013 will take place on October 29 – 31, 2013, in Santa Clara, and the detailed schedule for the event has just been made available. In the previous years, the conference was divided into  Chip Designs day (1 day), and the other 2 days were reserved for Software & System Design, but this year it does not appear to be the case. Whether you’ll be able to attend the event or not, it’s worth having a look at what will be discussed there in order to have a better understanding of what will be the key ARM developments in the near future in terms of hardware and software. There will be around 90 sessions categorized into 15 tracks: Accelerating Hardware Development – This track explores the resources, tools, and techniques that designers can employ to quickly bring hardware to market. Topics include multicore design, ARM IP, […]

Posted on by Jean-Luc Aufranc (CNXSoft) - 8 Comments on Wandboard Dual Benchmarks, Serial Console Fun, and Distributions List

Wandboard Dual Benchmarks, Serial Console Fun, and Distributions List

Since last time I tried Android and Ubuntu on the Wandboard, a few things happened. I’m not talking about Wandboard Quad announcement, but instead I received a Class 10 SD card, which makes the system so much responsive, and a RS232 to USB adapter so that I can access the serial console. So today, I’ll publish some benchmark results on Wandboard Dual since none appear to be available, and play a little with the serial console. A few things also happened on the operating systems side with more distributions now available for the board. Prerequisites I ran benchmark in Android, so I installed the latest Android 4.1.2 image (11th of April 2012) to my new SD card (ADATA 16 GB Class 10), and contrary to my poor experience on a 4GB Class 4 micro SD, everything was very fluid. I’ve also installed Google Play in order to install the applications. […]

Using ARM Development Studio 5 (DS-5) Streamline with MK802II mini PC

MK802-II is an Android 4.0 mini PC powered by AllWinner A10 (ARM Cortex A8) with 1GB RAM and 4GB flash. Instructions are also available to run Ubuntu, or other Linux distributions. ARM Development Studio 5 (ARM DS-5) is software development tool suite for ARM processors that can be used for both Linux and Android debugging, and available in 2 versions: professional edition and community edition, the latter being free of charge. I’m writing about both today, because Bob Peng, Technical Marking Engineer for ARM China, recently wrote a blog post in Chinese [Update: An English version is now available] showing how to use MK802-II, preloaded with the required drivers and daemon, with DS-5 Streamline Performance Analyzer with is part of both versions. The community edition may be missing some features of Streamline however. Streamline Performance Analyzer allows you to: Find out which modules or functions to take up most of […]
