Linaro 12.01 Release with Kernel 3.2 – Android 4.0.3

Linaro has just released version 12.01 based on Linux Kernel 3.2 and Android ICS upgraded to 4.0.3.  A lot of work has been done to have video hardware decoding on OMAP 4 (in GStreamer) enabling Pandaboard to run Ubuntu TV and XBMC with Video HW acceleration. Prebuilt binaries for Linaro GCC and Linaro GDBare now available which means you don’t need to use Ubuntu with Linaro Toolchain. It has been tested with Debian 6.0.2, Fedora 16, openSUSE 12.1 and Red Hat Enterprise Linux Workstation 5.7 and should run on any Linux Standard Base 3.0 compatible distribution. Windows binaries are also available and known to work on Windows XP Pro SP3, Windows Vista Business SP2 and Windows 7 Pro SP1. Here are the highlights of the release: Android Linaro’s ICS has been upgraded to 4.0.3. Linaro Android ICS builds are now optimized using -O3 with the Linaro Toolchain. Click through builds […]

Ubuntu TV Works on OMAP4 Pandaboard

Ricardo Salveti, Software Engineer at Canonical,  has written a blog post saying that Ubuntu TV now support full video hardware acceleration on the Pandaboard, TI OMAP 4 low cost development board. A demo of Ubuntu TV on the ARM platform with Ubuntu TV UI and 720p/1080p video playback can be seen in the video below. Pandaboard is the first ARM platform that can fully run Ubuntu TV. If you have a Pandaboard, you can try it out by installing the packages available at Linaro’s Overlay PPA. Qt and Qtmobility are not there yet (Patches are available at https://github.com/robclark/qtmobility-1.1.0), but he said they would be soon. The source code for Ubuntu TV is available at https://code.launchpad.net/~s-team/ubuntutv/trunk   Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011.

Android Drivers Will Be Included in Linux Kernel 3.3

The Android drivers were no longer accepted in the mainline Linux kernel, starting with Linux kernel 2.6.33, as announced by Greg Kroah-Hartman back in spring 2010. But this is about to change, as it appears that Greg Kroah-Hartman will include the Android drivers into his development branch for the upcoming Linux kernel 3.3, making it boot on Android devices without being patched. The Linux Foundation’s Consumer Electronics workgroup, along with a group at Linaro and various individual developers, is working with Kroah-Hartmann on this project. Tim Bird, chair of the Architecture Group, announced the Android Mainlining Project on the 20th of December with the goal of coordinating work on integrating the Android features. Further information on this project is available on the wiki and developers can also sign up for the project’s mailing list to join the 15 other persons involved in the project.

Graphics Hardware Acceleration for Android 4.0 on Origen and Snowball Development Boards

Last week, Linaro Android team announced that graphics hardware acceleration (2D and 3D) was coming to Android 4.0 for ST Ericsson Nova A9500 Snowball and Samsung Exynos 4210 Origen development boards. They have now release 2 videos to show the progress on the implementation. The first video (around 5 minutes) showcases Samsung Origen development board running Linaro’s build of Android ICS with 2D and 3D demo. The second video (1:21) shows 2D hardware acceleration on ST Ericsson Snowball board. Snowball Android 4.0 daily snapshots and instructions are available at https://android-build.linaro.org/builds/~linaro-android/staging-snowball/ and Origen builds at https://android-build.linaro.org/builds/~linaro-android/staging-origen/ The official December 2011 releases should also come pretty soon are available at http://releases.linaro.org/11.12/android/.

Android 4.0 Hardware Graphics Acceleration Coming to More Platforms

The Linaro Android Platform Team has just posted a weekly update to their progress. They are going to release 11.12 very soon with hardware graphics acceleration to 2 of their members development boards: ST Ericsson Nova A9500 Snowball and Samsung Exynos 4212 Origen boards. So if you have any boards or products based on those processors you should be able to get an hardware optimized version very soon. Hardware acceleration is already available on all OMAP4 platform such as Pandaboard, since this was the default Android ICS target. They also introduced support for the ARM DS-5 debugger, an Eclipse plug-in to help developer create high performance performance  and low power native software by integrating a graphical debugger for code generated for the Android Native Development Kit (NDK) and a basic version of the ARM Streamline performance analysis tool. Here’s a list of this week achievements: Key Points for wider discussion […]

Posted on by Jean-Luc Aufranc (CNXSoft) - No Comments on Build the bootloaders (U-boot & X-Loader) for Pandaboard

Build the bootloaders (U-boot & X-Loader) for Pandaboard

I’ve tried to compile u-boot and x-loader for Pandaboard by following the instructions given at http://omappedia.org/wiki/Get_started_with_ubuntu_on_omap4#Bootloaders. I did this in Ubuntu 10.04 LTS with Linaro gcc compiler. Here are the instructions for the build: Create the folders:

Get u-boot and checkout the omap4_dev branch:

You may use a different tag. Simply run “git tag -l | grep L24” to see the list of tags. (I used the latest at the time of this post). Build u-boot for OMAP4

At this point, you should get U-boot (u-boot.bin). get x-loader and checkout the omap4_dev branch:

N.B: Both u-boot and x-loader folders must be at the same directory level. build x-loader for OMAP4:

The x-loader (MLO) should now be ready. Finally, you simply need to copy MLO and u-boot.bin files to the SD card. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting […]
