"Any technology that does not appear magical is insufficiently advanced."
~ Gregory Benford
Linaro is pleased to announce the first Linaro Confectionery Release (LCR).
LCR is a reference build of the Android-5.0.1_r1 branch for ARM’s Juno and
Versatile Express TC2 hardware, and Fixed Virtual Platform (FVP) models.
The goal of LCR is to provides a foundation for tested Linaro engineering
efforts integrated with Android point releases. Only engineering efforts
which have an established validation record are allowed to be added to LCR.
LCR is conceptually similar to the Linaro Stable Kernel (LSK) project which
uses Greg Kroah-Hartman’s Long Term Stable (LTS) source tree with Linaro
members features added. LCR charts a comparable course that starts with
Android point releases and includes Linaro member directed engineering
to fix, optimize and enhance LCR.
For 14.12, LCR uses the Android AOSP 4.9 GCC toolchain for building 64bit
ARM binaries and the Android AOSP 4.8 GCC toolchain for building 32bit ARM
binaries.
LCR includes the 3.10 Android flavour of LSK for all 3 currently supported
configurations. This means that the LSK includes Android kernel patches from
the AOSP project. The Juno kernel includes ARM Mali drivers for accelerated 3D
graphics support.
LCR includes support for both single-arch 32bit ARMv7-A and multi-arch 32bit
ARMv7-A, 64bit ARMv8-A Android systems.
LCR is tested. CTS version 5.0, Android BIONIC tests, Android Monkey and other
tests are used to validate the system. Testing performed should not be
considered to exhaustive or necessarily product quality. Test results are
available to Linaro member companies.
The release can be found respectively at:
* Juno: http://releases.linaro.org/14.12/android/lcr/juno
* FVP: http://releases.linaro.org/14.12/android/lcr/fvp
* Versatile Express TC2:

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 OpenEmbedded-based images
=======================
With the Linaro provided downloads and with ARM’s Fast Models virtual
platform, you can boot a virtual ARMv8 system and run 64-bit binaries.
For more information please see:
http://www.linaro.org/engineering/armv8
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
