Cross Compiling Boost C++ Libraries for ARM

Boost provides free peer-reviewed portable C++ source libraries. Ten Boost libraries are already included in the C++ Standards Committee’s Library Technical Report and will be in the new C++11 Standard. The Boost C++ libraries are already included in popular Linux and Unix distributions such as Fedora, Debian, Ubuntu and NetBSD and are used by projects such as Python, Xibo, Civilization IV, etc.. Here are the steps to cross-compile Boost C++ libraries for arm using arm-linux-guneabi-g++: Download the source code: Extract the source code: Bootstrap the code: Modify the configuration file (project-build.jam) to use the ARM toolchain by replacing the line with “using gcc” by: Install the python development package: Build and install the boost libraries: This was tested in Ubuntu 11.04 (natty) and 10.04 LTS with linaro g++ toolchain.

How to Transfer files between the Host and Qemu via SSH and NFS

Last week, I wrote a blog post explaining how to copy files to a qemu image by mounting the qemu image in the host. This is only useful if emulated platform does not support networking. If networking is enabled, using SSH (Secure Shell) or NFS (Network File System) is more convenient. Using SSH with Qemu To initiate the SSH connection from qemu, there is actually nothing extra to do as long as you have sshd installed and running on the host. If it is not installed simply run  sudo apt-get install openssh-shell on the host. This will install and automatically sshd. To initiate the SSH connection from the host, you’ll have to redirect the ssh port to an unknown port and start qemu as follow (for overo): sudo qemu-system-arm -M overo -m 256 -drive file=./overo_sd_alip.img,if=sd,cache=writeback -clock unix -serial stdio -device usb-kbd -device usb-mouse -redir tcp:2222::22 Please refer to Beagleboard Emulator in Ubuntu with Qemu for the detailed instructions on how …

Samsung Unveils New Dual-core Exynos 4212 Processor

Samsung unveiled its new Exynos processor this week at Samsung Mobile Solution Forum 2011 in Taipei, Taiwan. The Exynos 4212 is a dual core ARM Cortex A9 processor clocked up to 1.5 GHz and “will improve processing power by 25 per cent and enhance a device’s 3D abilities by a massive 50 per cent” according to Samsung. The processor will also consume 30 percent less power than its predecessor (Exynos 4210) thanks to Samsung new 32nm HKMG process. Finally the company said that the Exynos 4212 will incorporate a rich portfolio of advanced codec accelerators that support digital still images, video recording and play-back at 1080p full-HD resolution, an image signal processor and an on-chip HDMI 1.4 interface. Samsung’s Exynos 4212 processor will sample to select customers in Q4 2011. Samsung also announced a website dedicated to Exynos processors. This website has a lot of information on Exynos 3110 and 4210 including showcase of products using those 2 processors, related …

NFC Forum Releases Simple NDEF Exchange Protocol (SNEP) Specification

The NFC Forum announced the release of the 16th specification of Near Field communication (NFC) dealing with the Simple NDEF Exchange Protocol (SNEP). NDEF stands for NFC Data Exchange Format. This data format has been described in an earlier specification released in 2006. SNEP is an extension of NDEF and defines protocol suitable for peer-to peer communication between two NFC-enabled devices. Previously, NDEF was applicable only to NFC tags in reader/writer mode. Now, SNEP enables the use of the openly standardized NDEF in peer-to-peer mode, making seamless interchange of data a reality. Application developers no longer need to concern themselves with how their NDEF data gets transferred between NFC-enabled devices. By providing this capability, the SNEP specification makes the difference between reader-writer and peer-to-peer operation modes disappear. SNEP Use Cases Here are two examples of potential applications for NFC technology developed with the new SNEP specification: Simplified transfer of contact information – one person’s phone can be configured to automatically …

Tizen: Linux Based OS with HTML5 Application Programming Interfaces

Earlier this week, the Linux Foundation announced yet another new Linux-based open source operating system for mobile and consumer devices based on Web standards called Tizen. This project is backed by Intel and Samsung who have already been involved with Linux based operating systems before, respectively with MeeGo and Bada. Both companies will be part of the technical steering team. It looks like Tizen will replace Meego overtime. Meego developers blasted the move and posted  angry comments especially in relation to Qt support and the fact that all the previous work put into the project has probably gone to waste. My take is that using HTML5 is probably not such a bad ideas as many applications are currently developed in HTML5/Javascript for Chrome Webstore for example, and it could make porting those to Tizen straightforward. Tizen will support multiple device categories including: Smartphones Tablets Smart TVs Netbooks In-vehicle infotainment devices The most intriguing and interesting part of this operating system …
