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. […]

Emcraft Systems K70 SoM is a system-on-module powered by Freescale K70 Cortex M4 micro-controller with enough RAM (64 MB) to comfortably run uClinux. They used to charge $99 for their uCLinux BSP, but it’s now free of charge, and the company also provides full hardware and software documentation, including a getting started guide, schematics and BoM for the baseboard, application notes and more… Many of their clients want to use Wi-Fi with K70 SoM, and it can easily be done by using Wi-Fi USB dongles based on Ralink RT5370 chipset such as D-Link DWA-140 (H/W rev B3) or Comfast CF-WU815N. Emcraft has provided detailed instructions to do so with K70 SoM, their latest baseboard (SOM-BSB-EXT) and a demo image based on their uClinux BSP. I’ll summarize the instructions to use K70 SoM as a Wi-Fi access point below. Connect the baseboard and K70 SoM with an Ethernet cable, a mini […]
PowerUSB power strips are four outlets power strips designed to help users save power by better understanding their devices power consumption, and automatizing tasks such as power on/off using timers, printer on/off controls, and more. One outlet is always on (for the main computer) and the 3 remaining outlets can be controlled via USB and the control software installed in a Linux, Mac or Windows x86 machine. The three of the four outlets are controlled through the software. Those power strips should allow lower electricity bills, and cover the cost of the strips ($69 to $129) within a few months. There are 4 models: PowerUSB Basic – $69.99 – The simplest model. You can control the 3 programmable outlets with on/off timers and keyboard shortcuts. PowerUSB Digital IO – $109.99 – This version adds 5 digital input/output lines for instrumentation and automation. The current model has 3 inputs and 2 […]

LinuxCon (North America) 2012 will take place on August 29 – 31, 2012 at Sheraton Hotel & Marina, in San Diego, California. The event will be co-located with the Linux Kernel Summit, the Linux Plumbers Conference, and CloudOpen 2012. LinuxCon consists of 3 days of keynotes, business and developers related sessions as well as tutorials. There will be over 80 sessions and keynotes during those 3 days. I’ll highlight a few sessions that I find particularly interesting and related to embedded Linux, software development and ARM. August 29 10:45 – 11:30 – Life After BerkeleyDB: OpenLDAP’s Memory-Mapped Database by Howard Chu, Symas Abstract: OpenLDAP’s new MDB library is a highly optimized B+tree implementation that is orders of magnitude faster and more efficient than everything else in the software world. Reads scale perfectly linearly across arbitrarily many CPUs with no bottlenecks, and data is returned with zero memcpy’s. Writes are on […]
Canonical is pushing to move Ubuntu beyond Desktop PC, and we’ve already seen some mockups for Ubuntu Smartphones and the recent Ubuntu TV announcement. The Ubuntu smartphone is not there yet, but Canonical has another idea: running Ubuntu Desktop on your multi-core Android smartphone connected to a TV/Monitor via its HDMI or MHL interface, making Canonical, another company joining “your smartphone is your laptop” trend. Ubuntu for Android will provide a full desktop experience and include office software (which apparently is Google Docs…) , web browsers (Chromium and Firefox), an email clients (Thunderbird) and media applications on Android phones docked to a screen and keyboard. Canonical claims the transition between Android and Ubuntu is seamless thanks to tight integration with the Android service layer. Ubuntu and Android share the same kernel. When docked, the Ubuntu OS boots and runs concurrently with Android. This allows both mobile and desktop functionality to […]
Teradici has developed PCoIP (PC-over-IP) protocol, a technology that allows to run a full desktop remotely over the network on thin clients, desktops, integrated displays, laptops and even Android tablets. The PCoIP protocol compresses, encrypts and encodes the entire computing experience at the data center and transmits it ‘pixels only’ across any standard IP network to stateless PCoIP zero clients. The PCoIP protocol is implemented in silicon for hardware accelerated performance and in software in VMware View. It supports high resolution, full frame rate 3D graphics and HD media, multiple large displays, full USB peripheral connectivity, and high definition audio all via LAN or WAN networks. A typical network made of PCoIP clients is shown below. Teradici emphasizes three key features of PCoIP technology: PCoIP technology uses host rendering Most other remote desktop technologies uses client rendering which may not be optimal and requires somewhat powerful clients. PCoIP uses host […]
