Linaro Releases

About the Reference Linaro Confectionary Release for HiKey (Multi-arch 64-bit)

This Reference Linaro Confectionary Release is the first release for 96boards HiKey board,
it is based on the Marshmallow android-6.0.0_r26 branch. This build is a
userdebug variant build, which contains multi-arch support allowing full use of the
64-bit ARMv8-A architecture, supports both 64-bit and 32-bit
applications and has selinux enabled by default.

The kernel used for this build is based on the AOSP version 4.1 common kernel,
and includes the ARM Mali drivers for 3D graphics acceleration support.

The sources are built using AOSP gcc 4.9 version for both 64bit and 32bit.
To switch to permissive mode, pass “androidboot.selinux=permissive” as
the boot parameter in the GRUB bootargs configuration.

The Android AOSP software provided in this release is functionally
tested with CTS version 6.0 R1 and the CTS results are shared with
members. We also added some benchmark test 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).

Note:
This release is only fully tested and verified with the 4GB emmc hardware
version, so there might be problem if used it on the 8GB emmec hardware version.
If you met any problem in that case, please file bugs as described in the “Support”
section below, we will take care of it for next release.

What is new

• Kernel was updated to use the 4.1 version
• Fixed the problem of creating /storage/sdcard0

Prerequisites

Please download the uefi binaries from here
and flash them into your HiKey board according to the instructions here

If this is the first time you use Hikey board, please reference here for the initial setup instructions:

Get artifacts

Click on each link to download:

• boot_fat.uefi.img.tar.xz
• system.img.tar.xz
• userdata.img.tar.xz(for 4G board) or userdata-8gb.img.tar.xz(for 8G board)

Boot Hikey board to fastboot mode

Connect the Link 1-2 and Link 5-6 of the Jumper15 on your Hikey board,
Connect a standard microUSB to USB connector between the HiKey microUSB port
and your Linux PC. Connect the HiKey power supply to the board, and run
following command to check if the board is in fastboot mode:

$ sudo fastboot devices
0123456789abcdef fastboot
$

Flash images

Uncompress the downloaded .tar.xz files using your operating system file manager,
or with the following command for each file:

$ tar -Jxf [filename].tar.xz

Flash the uncompressed files into the Hikey board under fastboot mode with
following commands:

$ sudo fastboot flash boot boot_fat.img
$ sudo fastboot flash system system.img
$ sudo fastboot flash userdata userdata.img

Boot HiKey board with Android images

Connect the link 1-2 and remove the link 3-4 and link 5-6 of the Jumper15 on your Hikey board,
connect the microUSB to you host pc, and plug in the power supply cable,
this will make your board boot the flashed android images by default.

You can use following command to check if the adb connection is connected:

$ adb devices
List of devices attached
0123456789  device

Linaro Android Source Code

Download the Android building script linaro_android_build_cmds.sh for this build
from the list of artifacts listed above, and run it.
This script will help to download the entire source code for both Android and
the kernel and attempt to build it.

Most commonly used options for linaro_android_build_cmds.sh:

$ ./linaro_android_build_cmds.sh -h #To print the script usage
$ ./linaro_android_build_cmds.sh -t #To build from the tip of the branch without overlay
$ ./linaro_android_build_cmds.sh -t -o <overlay> #To build from the tip of the branch with provided overlay
$ ./linaro_android_build_cmds.sh -m <pinned_manifest> -o <overlay> #To reproduce an exact build from pinned manifest
$ ./linaro_android_build_cmds.sh -t -l <login-id> #Provide login/access ID to clone and build code from linaro-private repositories

The pinned manifest(pinned-manifest.xml(?) and source manifest(source-manifest.xml) can be found from the list of artifacts

Compiling Linaro Android RootFS+Kernel

The following simple steps download, install and compile a complete Linaro Android distribution

• Download and install Ubuntu 14.04 64 bit or newer (download)
• Accept the EULA and download the Mali graphics (vendor.tar.bz2) libraries from here
• Download the Android building script for this build from the list of artifacts

• Run the script

Build from the tip of the source:

chmod a+x linaro_android_build_cmds.sh
./linaro_android_build_cmds.sh -o $PWD/vendor.tar.bz2 -t

Or reproduce the exactly the same as this buid:

chmod a+x linaro_android_build_cmds.sh
./linaro_android_build_cmds.sh -o $PWD/vendor.tar.bz2 -m pinned-manifest.xml
