About Linaro

Linaro.jpg
Linaro™ is a Not For Profit (NFP) organization that aims to make embedded open source development easier and faster. Linaro will create a common software foundation for software stacks and distributions to land on and provide the best open source tools for developers to develop on. The focus is on low level software around the Linux kernel that touches the silicon, key pieces of middleware that enable new markets and tools that help the developer write and debug code. Linaro aims to maximize the potential of the latest features of ARM-based processors, helping provide optimized performance in a lower power envelope. Linaro is both a community and a supported project with engineering teams spread globally.

Overview of How-To

This How-To is meant to be a starting point for people to learn install a Linaro image for OMAP3-based IGEP platforms as quickly and easily as possible.

Unless otherwise noted, this How-To works with the Ubuntu 10.10 but most of the contents are valid also for other GNU/Linux distributions. We do not issue any guarantee that this will work on other distributions.

Linaro releases

At the end of each cycle linaro do an integrated build of software with this variants:

  • Headless (no graphical UI)
  • Netbook (Netbook style UI)
  • ARM Linux Internet Platform (ALIP)
  • Handset (A KDE/Plasma based user interface)

Linaro 10.11

Install needed packages, on Ubuntu 

sudo apt-get install uboot-mkimage uuid-runtime realpath

Next create a working directory 

mkdir linaro
cd linaro

Download latest linaro tools to a location in your PATH, e.g. $HOME/bin/: 

wget http://downloads.igep.es/linaro/10.11/linaro-hwpack-create
wget http://downloads.igep.es/linaro/10.11/linaro-hwpack-install
wget http://downloads.igep.es/linaro/10.11/linaro-media-create
cp linaro-image-tools/linaro-media-create $HOME/bin
cp linaro-image-tools/linaro-hwpack-* $HOME/bin

Now it's time to download the software image and the hardware pack for our target. We've download the Netbook style UI image, but you can download another (http://releases.linaro.org) 

wget http://releases.linaro.org/platform/linaro-m/netbook/final/linaro-m-netbook-efl-tar-20101108-1.tar.gz
wget http://releases.linaro.org/platform/linaro-m/hwpacks/final/hwpack_linaro-igep_20101109-1_armel.tar.gz

Installing the build onto a media that your hardware can recognise is done using the linaro-media-create script.

  1. Insert your SD card into the host machine (the machine you downloaded the image and hwpack to).
  2. Ensure you know the device node for your sd card reader. In the following example we assume /dev/mmcblk0. If you are unsure of the device node of your SD card, remove and reinsert the card and type dmesg on the command line. The last few lines should give you the device node of the card you just inserted.
  3. In the directory where you downloaded the image and hwpack run linaro-media-create (NOTE: be sure to delete all partitions on the SD Card before running linaro-media-create otherwise it will fail!)
linaro-media-create --rootfs ext3 --mmc /dev/mmcblk0 --dev igep \
                   --binary linaro-m-netbook-efl-tar-20101108-1.tar.gz \
                   --hwpack hwpack_linaro-igep_20101109-1_armel.tar.gz

Finally, plug the SD card in your board and boot.

Linaro wifi kernel support

You can download the kernel images release 2.6.35-1010.17 with wifi support from our website:

  1. Kernel link.
  2. Kernel headers.

SGX Acceleration [EXPERIMENTAL!]

This worked for me, no idea if it works for anyone!

1. Install the linux kernel headers for the linaro version that is running on your board in my case 

sudo apt-get install linux-headers-2.6.35-1008-linaro-omap

2. Get the openGL backend: 

sudo apt-get install libegl1-sgx-omap3 libgles1-sgx-omap3 libgles2-sgx-omap3

Now you can run the demos that are mentioned in the Ubuntu guide. Have fun emoticon.
