Linaro 12.08 released

“Coming together is a beginning; keeping together is progress; working
together is success.“ ~ Henry Ford

The Linaro 12.08 release is now available!

The Linaro 12.08 release highlights the combined work of all the Linaro
Teams – Working Groups, Landing Teams and Platform Teams – who have
provided all the updates and new features that are integrated on top of
Android and Ubuntu during this development cycle. The 12.08 release is
another example of how Linaro succesfully--together with its members,
partners and community--continue to build the future of Linux on ARM.

12.08 was a very busy cycle for the Linaro Android platform team,
"During the cycle our number one goal was to create stable Jelly Bean
builds from AOSP for all of the platforms we support," said Zach
Pfeffer, Tech Lead for the Linaro Android Team. "Not only did the team
achieve this goal, but also continued to create a world class Android
benchmarking platform, made it easier for people to connect their Jelly
Bean based builds to the network by integrating the Ethernet
Configuration Manager and automated many of the tests in the AOSP
codebase," added Pfeffer. The Linaro Android team is already looking
toward the Linaro 12.09 development cycle and according to Pfeffer,
"We’re planning on getting each baseline working with Linaro’s
linux-linaro upstream tracking kernel, continuing to improve our
benchmarking infrastructure and maybe, just maybe having a very
preliminary 64-bit Android build (fingers crossed)".

The Developer Platform Team announced USB Host enablement is now
available in LAVA and that all packaged linux-linaro kernels are now
cross-compiled and boot tested via LAVA before they are uploaded to
Linaro Overlay PPA. Additionally, U-Boot-Linaro is now based on
the latest upstream release--v2012.07.

We encourage everybody to use the 12.08 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/GetSource
http://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
