Linaro Releases

About the Reference Linaro Confectionary Release for AM572x Evaluation Module(referred to as X15 in this document)

This Reference Linaro Confectionary Release is the release for X15 board,
it is based on the Oreo android-8.1.0_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 mirror from http://git.ti.com/android/kernel,
built with the default AOSP toolchain 32bit gcc4.9.
The version is based on version 4.4.

The userspace components are built with AOSP prebuilt clang binary,
the version is “Android clang version 5.0.300080 (based on LLVM 5.0.300080)”.

The AOSP software provided in this release is functionally
tested with CTS version 8.1 R1 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).

What is new

• AOSP source updated to base on android-8.1.0_r7 version
• CTS test package update to use 8.1 R1 version
• The security patch is 2018-01-05
• Fixed UI performance regression problwm caused by hw vsync timeout

Prerequisites

Get “OTG cable” and “Serial console cable” connected between the X15 board and your PC.

If this is the first time you use X15 board, please reference here for the initial setup instructions.

Get artifacts

Click on each link to download:

• MLO
• u-boot.img
• am57xx-evm-reva3.dtb
• boot.img
• system.img
• userdata.img
• vendor.img

Boot X15 board to fastboot mode

Press power or reset button to start the X15 board, and on the serial console,
get to U-Boot shell on device and run next command to enter fastboot mode:

    => fastboot 1

Then on the host side, run following command to make sure it’s in fastboot mode:

$ fastboot devices
0e005017394200e2    fastboot
$

Flash images

Flash the downloaded image files into the X15 board under fastboot mode with
following commands:

$ fastboot flash xloader MLO
$ fastboot flash bootloader u-boot.img
$ fastboot flash environment am57xx-evm-reva3.dtb
$ fastboot flash boot boot.img
$ fastboot flash system system.img
$ fastboot flash userdata userdata.img
$ fastboot flash vendor vendor.img

Boot X15 board with AOSP images

Run “fastboot reboot” or press the reset button to restart X15 board
after the fastboot flash commands, then the X15 board will boot with
the AOSP images just flashed.

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

$ adb devices
List of devices attached
0e005017394200e2  device
$

Linaro AOSP Source Code

Download the AOSP 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 of AOSP 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 -u <url-aosp-mirror-manifest> #As -t, but repo sync from local mirror
$ ./linaro_android_build_cmds.sh -m <pinned_manifest> #To reproduce an exact build from pinned manifest
$ ./linaro_android_build_cmds.sh -m <pinned_manifest> -u <url-aosp-mirror-manifest> #As -m, but repo sync from local mirror

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