The Linaro 12.11 release is now available!
The Linaro 12.11 release cycle highlights the determination and hard
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 12.11 release is another example of how Linaro
works together with its members, partners and community to continue to
build the future of Linux on ARM.
Looking over the higlights from the 12.11 release cycle, it's easy to
see how the momemtum and energy from LCE12-Copenhagen carries over and
our teams consistantly meet and exceed the goals set in the Linaro
Connect sessions. Our Android team has updated the platform to AOSP 4.2
on all our supported boards, and Android evdev is now upstreamed and
used in AOSP 4.2.
As we look over improvements to the Linaro toolchain, it is notable
that Linaro GCC now includes the arm/aarch64-4.7-branch (ARMv8).
The Developer Platform team reports that the initial GRUB support for
ARM is now available, provided by our Linaro Enterprise Group and
marking its first component.
The Power Management Working Group continues its progress on big.LITTLE
MP by delivering the v11 and v12 branches, as the Graphics Working Group
notes that there is a new GLMark2 release which demonstrates shadow
mapping. Additionally our LAVA team reports that the NI Battery
Simulator is now available in the lab and can now be accessed remotely.
We encourage everybody to use the 12.11 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
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
