h2. About the Linaro Confectionary Release for Versatile Express (Aarch32)
The Linaro Confectionary release is based on the AOSP Lollipop Android-5.1.0_r1 version. This reference build is a userdebug variant build, and it contains support allowing full use of the 32-bit ARMv7-A architecture and supports the 32-bit applications, with SELinux enabled by default. The release uses the Linaro Stable Kernel version 3.10. The sources are built using Android (AOSP) GCC 4.8. To disable SELinux pass "selinux=0" as the boot parameter in the UEFI bootargs configuration.
The Android AOSP software provided in this release is functionally tested with CTS version 5.0 and the CTS results are shared with members. The BIONIC component is validated with Android BIONIC tests. Android Monkey tests were run for stress testing. We also added some benchmark test to observe the performance trend in various field.
Sources are also made available so you can build your own images (see the "Building from Source tab":http://releases.linaro.org/15.03/android/vexpress-lcr#tabs-2).
h3. What is new
* Android source changed to based on the Lollipop Android-5.0.2_r1 version
* Verified with application-benchmark test on LAVA.
h2. About the Android flavour of Linaro Stable Kernel (LSK)
The kernel used by Linaro Confectionary Release for Versatile Express is the Android flavour Linaro Stable Kernel (LSK), which is produced, validated and released by Linaro and is based on the Linux stable kernel tree. The LSK focuses on quality and stability and is therefore a great foundation for product development. It also includes backports of commonly desired features, provided they meet the quality requirements, and also any bug fixes.
Sources are also made available so you can build your own images (see the "'Building from Source'":http://releases.linaro.org/15.03/android/vexpress-lcr#tabs-2).
