About the Reference Linaro Confectionary Release for AM65X Evaluation Module(referred to as AM65XEVM in this document)
This Reference Linaro Confectionary Release is the first release for AM65XEVM board,
it is based on the Pie android-9.0.0_r34 branch. This build is a
userdebug variant build, which contains support for allowing full use of the
Cortex-A53 architecture, supports both 32-bit and 64-bit applications, and run in permissive mode.
The kernel used for this build is from http://git.ti.com/ti-linux-kernel/ti-linux-kernel,
which the version is based on version 4.19.
The kernel is built with the AOSP CLANG version of clang 8.0.8 (based on r349610),
which could be gotten by cherry picking the commit here,
The userspace components are built with AOSP prebuilt clang binary,
which the version is “Android (4691093 based on r316199) clang version 6.0.2”
The AOSP software provided in this release is functionally
tested with version 9.0 R7 based CTS package and VTS package generated based on the android-vts-9.0_r8 branch,
the test results of both CTS and VTS 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 is based Pie android-9.0.0_r34
- CTS test package updated to use 9.0 R7 version
- VTS test package updated to use 9.0 R8 version
- The security patch is 2019-03-05
- Kernel is based on 4.19 version with PVR source included

AOSP Patch Summary
There are patches developed by TI and Linaro engineering teams were applied
to get AOSP booting to UI on the X15 development platform.
These patches can be found on Linaro Git repositories via files:
- P-RLCR-PATCHSET
- am65x-p-workarounds
Some of these patches have been submitted to AOSP and are being tracked for acceptance.
Any patches can be contributed through the instructions described Here
Known Issues and Limitations
Here are some known issues for this release build:
- Boottime test failed to run to complete because of the change on framework side, investigation in progress
- Weekly job failed because of the stringbench test took too much time
- Piglit and media codec tests not enabled, work is in progress.
- The apk benchmark tests failed to run to complete because governor is not enabled.
- The CTS test pass rate is 99%, 2599 of 419273 test cases were reported as failure.
- The VTS test pass rate is 35%, 9380 of 14455 test cases were reported as failure.
All the test failures reported by this release build had been created as bugs on Linaro bugzilla.
With fixes applied, some of them might be closed, new bugs might be created as well when new changes merged.

Prerequisites
Get “OTG USB cable” and “UART USB cable” connected between the AM65x EVM board and your PC according to the instructions here

Config to Boot from eMMC
Configure SYSBOOT DIP-switch for booting from eMMC (user area mode):
SW2[0:3] = 0000 SW3[0:3] = 0110 SW4[0:1] = 00
Boot the board to fastboot mode
Power up the AM65xEVM board, and on the serial console, get to U-Boot shell on device
and run next commands to prepare the U-Boot environment:
=> env default -f -a => setenv partitions $partitions_android => env save => fastboot 0
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 AM65xEVM board under fastboot mode with
following commands:
$ fastboot oem format $ fastboot flash tiboot3 tiboot3.bin $ fastboot flash bootloader bootloader.img $ fastboot flash boot boot_fit.img $ fastboot flash system system.img $ fastboot flash vendor vendor.img $ fastboot flash userdata userdata.img
Boot AM65xEVM board with AOSP images
Run “fastboot reboot” to restart AM65xEVM board after the fastboot flash commands finished successfully,
then the AM65xEVM 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 $
Prerequisites
Get “OTG USB cable” and “UART USB cable” connected between the AM65xEVM board and your PC according to the instructions here
Getting Linaro AOSP Source Code and Compiling firmware, kernel, AOSP images
The following simple steps to download, install and compile a complete Linaro AOSP distribution
- Establishing a Build Environment as described here
- Download the Linaro LCR building script
- Run the linaro-build.sh script downloaded, and answer the questions when promopted
Download the Linaro LCR build script
Download the Linaro LCR building script linaro-build.sh as following for projects repo sync and patch applying;
$ mkdir workspace && cd workspace # create new directory as workspace, using existing workspace would be OK as well $ wget https://android-git.linaro.org/android-build-configs.git/plain/linaro-build.sh -O linaro-build.sh # get the linaro-build.sh script $ chmod +x linaro-build.sh # make it executable
Repo sync projects and build images
Run as following to start repo syncing and build firmwares, kernel, Android images for the AM65xEVM board:
$ ./linaro-build.sh -c lcr-reference-am65x-p # To build from the tip of the branch
This command would help to repo sync all the AOSP and necessary projects, apply necessary patches,
and build the firmware, kernel, Android images together.
And you could specify other options to use local mirror, only repo sync projects, only build images, etc.
Most commonly used options for linaro-build.sh are like following:
$ ./linaro-build.sh -h # To print the script usage $ ./linaro-build.sh -c lcr-reference-am65x-p -ss # Only build images without repo syncing AOSP source and applying patches $ ./linaro-build.sh -c lcr-reference-am65x-p -m <url-aosp-mirror-manifest> # Use local mirror for AOSP projects repo sync $ ./linaro-build.sh -c lcr-reference-am65x-p -pm <pinned_manifest> # To recreate the exact same build with the pinned manifest specified.
The pinned manifest(pinned-manifest.xml(?) and source manifest(source-manifest.xml) can be found from the list of artifacts
For example, to build from the tip of the source:
./linaro-build.sh -c lcr-reference-am65x-p or ./linaro-build.sh -c lcr-reference-am65x-p -m <url-aosp-mirror-manifest>
Or to reproduce the exactly the same as this buid:
./linaro-build.sh -c lcr-reference-am65x-p -pm pinned-manifest.xml or ./linaro-build.sh -c lcr-reference-am65x-p -pm pinned-manifest.xml -m <url-aosp-mirror-manifest>
Deploy AOSP Images to the AM65xEVM board
Power up the AM65xEVM board, and on the serial console, get to U-Boot shell on device
and run next commands to prepare the U-Boot environment:
=> env default -f -a => setenv partitions $partitions_android => env save => fastboot 0
Then on the host side, run following commands to flash the images into the AM65xEVM board:
$ fastboot oem format $ fastboot flash tiboot3 tiboot3.bin $ fastboot flash bootloader bootloader.img $ fastboot flash boot boot_fit.img $ fastboot flash system system.img $ fastboot flash vendor vendor.img $ fastboot flash userdata userdata.img
