Ethernet now works on Panda, Staging Panda, Beagle, Beagle xM, Staging Snowball. QA on all boards for the 11.09 Linaro Android Builds. Daily builds of Android toolchain against gcc-linaro bzr repository is provided. Android is now compiled with GCC4.6 with -O3. Busybox is built from source in all Android builds. glmark2 added to all the official builds for Android. Powertop is now available on Android. Linaro’s 11.09 toolchain has been benchmarked. All Android builds are running with the 11.09 toolchain. The MLO that Panda and Staging Panda uses for Android uses gets built from source from the upstream git. An OMAP4460 Android build is available from android-build. Panda supports Bluetooth. Panda supports Wi-Fi. Snowball Android A-release from […]

Cross Compiling libavg for ARM

libavg is a high-level development platform for media-centric applications using Python as scripting language and written in C++. Bear in mind that are many dependencies with libavg 1.6. I have not built all the libraries required, but instead simply taken the pre-built binaries and header files in the qemu overo image and copied the files as follows: mkdir mnt sudo mount -o loop,offset=$[106496*512] overo_sd_alip.img mnt mkdir ~/edev/beagleboard/libs/lib -p mkdir ~/edev/beagleboard/libs/include cp mnt/usr/lib/* ~/edev/beagleboard/libs/lib/ -rf -d cp mnt/lib/* ~/edev/beagleboard/libs/lib/ -rf -d cp /mnt/usr/include/* ~/edev/beagleboard/libs/include -rf -d sudo umount mnt The -d flag skips the symlink, so we need to recreate then for all library so that the compiler can find instead of Save the following scripts to

and run it where the arm libraries are located (in my case in /home/jaufranc/edev/beagleboard/libs/lib, /home/jaufranc/edev/beagleboard/libs/lib/arm-linux-gnueabi and /home/jaufranc/edev/beagleboard/libs/lib/mesa). This will  create symlinks for most libraries, but not all. Some will still […]

Cross-Compiling Mesa 3D Graphics Library for ARM

Mesa is an open-source implementation of the OpenGL specification that can be used for software emulation or  complete hardware acceleration for modern GPUs.The Mesa library is used by a variety of games (e.g. Quake 2.3), libraries (e.g PyOpenGL), science and technical applications and utilities (e.g. xscreensaver). MesaLib requires X11 libraries. I’ll assume those are already cross-compiled here. For this build, I used pre-built X11 libraries found in ALIP (ARM Internet Platform) binaries. I used the method described here and copied the libs in /lib and /usr/lib and header files in /lib/include found in the qemu overo image respectively to /home/jaufranc/edeve/beagleboard/libs/lib and /home/jaufranc/edeve/beagleboard/libs/include. make sure you use the “-d” with cp to avoid copying the symlinks or some symbolic links would point to x86 binaries or files that do not exist. Here are the instructions to cross-compile MesaLib 7.11 for ARM using arm-linux-guneabi-gcc: Download the latest version of Mesa source code: […]

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):

Please refer to Beagleboard Emulator in Ubuntu with Qemu for the detailed instructions on how to setup qemu to emulate beagleboard or […]

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 […]
