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 […]

Android 4.0 on ST Ericsson Snowball Development Board

Android 4.0.1 can now run on ST Ericsson Nova A9500 low cost development board “snowball”. The build is available at https://android-build.linaro.org/builds/~linaro-android/staging-snowball/. You can Android 4 (ICS) it in action in the Snowball board in the video build using build number 84. This is a bit sluggish since Android 4 currently lacks hardware acceleration on this development board but Linaro and the igloocommunity will implement it in the next few weeks. If you have an ST Ericsson snowball board, here are the instructions to try the latest Android 4.0 build for the platform: Get the images: wget –no-check-certificate https://android-build.linaro.org/jenkins/job/linaro-android_staging-snowball/lastSuccessfulBuild/artifact/build/out/target/product/snowball/boot.tar.bz2 wget –no-check-certificate https://android-build.linaro.org/jenkins/job/linaro-android_staging-snowball/lastSuccessfulBuild/artifact/build/out/target/product/snowball/system.tar.bz2 wget –no-check-certificate https://android-build.linaro.org/jenkins/job/linaro-android_staging-snowball/lastSuccessfulBuild/artifact/build/out/target/product/snowball/userdata.tar.bz2 Get the linaro-image-tools and create the image: bzr branch lp:linaro-image-tools ./linaro-image-tools/linaro-android-media-create –mmc /dev/sdc –dev snowball_sd –system system.tar.bz2 –userdata userdata.tar.bz2 –boot boot.tar.bz2 MINICOM settings: minicom -D /dev/ttyUSB0 -w -C minicom.txt You must setup the boot args as follows: U8500 $ setenv loadbootscript fat load mmc 1:1 ${loadaddr} […]

Linaro’s Android Platform – ELCE 2011

Zach Pfeffer, Linaro Android Platform team leader, describes Linaro’s work on the Android platform and future plans at Embedded Linux Conference Europe 2011. Abstract: Linaro uses components from the Android Open Source Project, member companies, community supported efforts and Linaro engineering teams to build integrated, easy-to-use and well tested Android platforms for upstream work, product baselines and hobby projects. The team currently has platforms for TIs PandaBoard, BeagleBoard and Beagle xM, ST Ericsson’s Snowball, Samsung’s Origen and Freescale’s iMX53. They recently released platforms with Android 2.3.4 built against GCC 4.6 and running the 3.0 Linux kernel. In this session Zach reviews what’s been done, the Linaro Android concept, how Linaro brings Android together and what their plans are.

Build Community Android Distribution and Ensure the Quality – ELCE 2011

Jim Huang, developer and co-founder of 0xlab, explains how they built an Android distribution with Linaro at Embedded Linux Conference Europe 2011. Abstract: While developing Android distributions, 0xdroid and LEB (Linaro Evaluation Build), we learn much about the development approach to non-traditional open source software model such as Android Open Source Project. This session shares the experience how 0xlab established the community, contributes to upstream (in unusual way), and leveraged the strong efforts from Linaro. Also, 0xlab develops a serial of open source projects to ensure overall performance and quality for better user experience.

ARM Linux Kernel Alignment & Benefits For Snowball – ELCE 2011

Andrea Gallo, Chief Linux Architect in the Smartphone and Tablet Solution organization in ST-Ericsson and part of the Linaro Technical Steering Committee, explains how a common Linux ARM kernel benefits ST Ericsson Snowball development platform. Abstract: Last March, the ARM Linux community got shaken by the complaints by Linus Torvalds for its lack of proper structure and organization. This is totally true and mainly due to the large number of different SoC vendors, each one integrating the ARM IP’s in a slightly different variant. Linaro immediately accepted the challenge to drive the kernel alignment of the ARM community and most ARM Linux experts got together and agreed on the way forward as early as May 2011 at the Developers’ summit in Budapest. ST-Ericsson is a founding member of Linaro and some key ST-Ericsson engineers are assigned to Linaro and specifically to this kernel alignment working force. In the speech, Andrea […]

Optimizations for Cheap Flash Media – ELCE 2011

Arnd Bergmann, Linaro (and IBM), explains how NAND flash access can be improved in Linux embedded systems at Embedded Linux Conference Europe 2011. Abstract: Mass storage in embedded systems typically means NAND flash in the form of eMMC, SDHC or similar technologies. Unlike server-class SSDs, these have few optimizations that help reduce write-amplification. This presentation explains the typical shortcomings in this design and how system builders and software developers together can avoid them, in order to get longer life and better performance out of low-end media. You can also download the presentation slides.
