“Success is almost totally dependent upon drive and persistence.
The extra energy required to make another effort or try another
approach is the secret of winning.” ~ Denis Waitley
We are pleased to announce the release of Linaro 12.06.
Linaro 12.06 contains components delivered by all Linaro Teams
--Working Groups, Landing Teams and Platform Teams-- and brings an
abundance of exciting updates and new features which are integrated on
top of Android and Ubuntu. Linaro through these updates, fixes, and new
features continue to build the future of Linux on ARM and the 12.06
Linaro release delivers another winning combination off these components.
In the 12.06 release, the Linaro Android Team delivers multimedia
enablement on AOSP and those patches are now under review. The team now
has automated benchmarking applications (Monkeyrunner) working on both
the PandaBoard and Snowball boards.In addtion to the benchmarking now
working on PandaBoard; perf for Andoid on PandaBoard has been submitted
to the Linaro kernel maintainers for other ARM based processor boards
and lkml. For this release Linaro Android was also updated to Android
version 4.0.4 r2. Also of note; the video that Nicolas Charbonnier shot
during the Demo Friday event at Linaro Connect Q2.12 in Hong Kong about
the improvements to the Linaro Android toolchain continues to create
interest in this teams work and the future of the possibilities of
Android performance. More information on other exciting news
surrounding Linaro Android can be found in the release highlights.
The Linaro Developer Platform Team announced that the Kernel config
fragments are now being used by all kernel packages in the Linaro
Evaluation Builds (LEBs) and this includes one single fragment for the
Ubuntu Specific configs which allows for all builds to behave in a
similar fashion. Other updates include all Linaro Linux kernel packages
were updated to the latest development trees from Linux Linaro and the
Linaro Landing Teams. The Linux Linaro maintenance scripts are now
available and can be found on git.linaro.org; additionally improvements
have been made to the instructions and scripts to allow easier
cross-builing of packages using multi-arch with Ubuntu.
We encourage everybody to use the 12.06 release. The download links for
all images and components are available on our downloads page:

Using the Android-based images
=======================
The Android-based images come in three parts: system, userdata and boot.
These need to be combined to form a complete Android install. For an
explanation of how to do this please see:
http://wiki.linaro.org/Platform/Android/ImageInstallation
If you are interested in getting the source and building these images
yourself please see the following pages:
http://wiki.linaro.org/Platform/Android/GetSourcehttp://wiki.linaro.org/Platform/Android/BuildSource
Note: tilt-tracking build (LEB) doesn't contain accelerated SGX support
(only framebuffer video). For a full enablement support (graphics and
multimedia), please use OMAPZoom build from our Developers and Community
Builds section. In addition to those builds, a tilt-stable and an AOSP
based builds are provided.
Using the Ubuntu-based images
=======================
The Ubuntu-based images consist of two parts. The first part is a hardware
pack, which can be found under the hwpacks directory and contains hardware
specific packages (such as the kernel and bootloader). The second part is
the rootfs, which is combined with the hardware pack to create a complete
image. For more information on how to create an image please see:
http://wiki.linaro.org/Platform/DevPlatform/Ubuntu/ImageInstallation

"Perseverance is not a long race; it is many short races one after another."
~Walter Elliott
We are pleased to announce the release of Linaro 12.05.
Updates, new feature implementations, new ways to use the member boards
are all the short races in which we persevere in our efforts to support,
design, and build the future of Linux on ARM.
Linaro release 12.05 comes on the cusp of Linaro Connect in Hong Kong
where over 200 ARM developers, engineers, and more have descended on
the Gold Coast hotel to present, discuss and develop features,
infrastructure and optimizations for the Linux kernel, Android, Ubuntu.
During this Q2.12 Linaro Connect the spotlight is on the following
technologies:
* ARM big.LITTLE implementation
* Multicore power management and scheduling
* SoC BSP maintainance, cost reduction and upstreaming
* A15 Virtualization
* SoC Unified Memory Management
* ARM for the Enterprise: Servers and Beyond
Linaro engineers will "show off" demos which touch on the sessions and
support developed not only during this and past cycles, but refined as
part of the Q2.12 Linaro Connect and will highlight this work as part
of the Demo Friday event:
http://connect.linaro.org/events/linaro-connect-q2-12-demo-friday/
As part of the Linaro Connect Q2.12 event Linaro also took risks with
new free technologies now being offered as part of the Google+--Hangouts
on Air. All public sessions were live streamed to remote participants.
Our Android team even has this technology running on Samsung's Origen
board. The amazing story is that less than 6 months ago using
Google+ Hangouts wasn't possible on an ARM platform with an open source
distribution.
We encourage everybody to use the 12.05 release. The download links for
all images and components are available on our downloads page:
