About the Reference Linaro Confectionary Release for AM572x Evaluation Module(referred to as X15 in this document)
This Reference Linaro Confectionary Release is the first release for X15 board,
it is based on the Nougat android-7.1.0_r7 branch. This build is a
userdebug variant build, which contains support for allowing full use of the
Cortex-A15 architecture, supports 32-bit applications, and run in permissive mode.
The kernel used for this build is the prebuilt 4.4 version kernel.
The sources are built with AOSP LLVM 3.8 clang-2690385 (based on LLVM 3.8.256229),
and gcc 4.9 for 32bit.
The Android AOSP software provided in this release is functionally
tested with CTS version 7.0 R2 and the CTS results are shared with
members. We also added some benchmark tests to observe the
performance trend in various fields.
Sources are also made available so you can build your own images
(see the Building from Source tab).
