Is the AOSP master supported?

initialapex · October 31, 2019, 10:15am

Hello,

I’m trying to build the AOSP master branch for dragonboard 410c, but I think it is not work well. I follow the step as below link to build the android for my own, but it didn’t work. Building Android Open Source Project (AOSP) for Dragonboard - 96Boards

I use the prebuilt kernel(ignore the build kernel step), the board could be connected by adb , but the screen would keep on android logo for a few hours.
If I used the kernel that I build myself, the system would crash and return to the fastboot mode.

the questions is

Is the dragonboard 410c fully support the AOSP master branch?
The system look like 32bit system, but the kernel built is 64bit. Is it would be an issue?

Hey @jstultz is the board actively supported in aosp?

jstultz · October 31, 2019, 8:22pm

So no, db410c is not supported in AOSP right now.

Amit has a patch to add support here:
https://android-review.linaro.org/c/device/linaro/dragonboard410c/+/20479

But I’m not sure how current that patch is, and Amit has been out for a few weeks.

lucasrangit · November 13, 2019, 3:19pm

@jstultz

Is there a specific branch/tag/commit that is supported?

The guide uses master/HEAD but to workaround the duplicate path issue @initialapex reported (AOSP repo sync fail - #2 by initialapex), I use repo init -u https://android.googlesource.com/platform/manifest -b d3a70484da211b35c11b428b733844d6a36c11c6 (before AOSP adding a dragonboard device).

However, make then fails with the following.

FAILED: out/soong/build.ninja
out/soong/.bootstrap/bin/soong_build -t -l out/.module_paths/Android.bp.list -b out/soong -n out -d out/soong/build.ninja.d -globFile out/soong/.bootstrap/build-globs.ninja -o out/soong/build.ninja Android.bp

doitright · November 26, 2019, 4:27pm

The more correct solution to the duplicate path issue is to modify the local manifest, “linaro.xml” in BUILDROOT/.repo/local_manifests/

Add the following two lines to it above the first existing project entry;

  <remove-project name="device/linaro/dragonboard" />
  <remove-project name="device/linaro/dragonboard-kernel" />

Another thing that can be considered, since there hasn’t been any action on the DB410/820 repository since before AOSP10 was merged, is to use an older snapshot of AOSP. Note that picking an older platform manifest will only change what parts are included, and not roll back the state of those parts.

You can use the hikey/960 manifests that used to be maintained by @jstultz , since they represent a full snapshot of AOSP master at those dates.

If Amit happens to see this, it would be nice also to see some db820c code added to AOSP, since Arrow seems to actually have it in stock again, finally

Edit: I have both 410 and 820 working with this manifest;

You can try this;

I haven’t tried it on the 410c, only the 820c, but the changes I had to make for the 820c were in common, so it probably works for both.

Hello, I followed the instructions in the following link yesterday (Feb 13, 2020)

On top of those I did the following modifications

Removed following lines in .repo/manifest.xml file, as it was throwing duplicate path errors.
<project path="device/linaro/dragonboard" name="device/linaro/dragonboard" groups="device,dragonboard,pdk" />
<project path="device/linaro/dragonboard-kernel" name="device/linaro/dragonboard-kernel" groups="device,dragonboard,pdk" clone-depth="1" />
Added following line in device/linaro/dragonboard/db410c32_only/device.mk
PRODUCT_SOONG_NAMESPACES += external/mesa3d

The build succeeded, flashed using flash-all-aosp.sh script successfully. Up on boot, the display was blank. I was able to connect via adb. Couldn’t find window manager service running. Any one facing similar issue? How to proceed?

doitright · February 14, 2020, 7:55pm

I strongly suggest that you either start with my repository (see post before yours), or choose Android 9.

acn · February 16, 2020, 2:00am

Hello @doitright, is it possible for you to add a README file in your git repository on how to start with your work?

Edits: I removed “incorrect build steps” from my original post (intent: not to confuse others). Refer the discussions below for the correct steps.

doitright · February 15, 2020, 4:50pm

Look in the group root under the pinned-manifests repository.

acn · February 16, 2020, 2:26am

Followed the steps provided in link below.
https://gitlab.com/aosp-automotive/pinned-manifests

Steps as below (for reference)
$ repo init -u https:// android.googlesource.com/platform/manifest -b master
$ wget https:// gitlab.com/aosp-automotive/pinned-manifests/raw/master/pinned_020620.xml -O .repo/manifests/pinned_020620.xml
$ repo init -m pinned_020620.xml

But I get error, how to resolve this?

fatal: manifest 'pinned_020620.xml' not available
fatal: duplicate path device/linaro/dragonboard in /home/aananth/bsp/db410c/.repo/manifests/pinned_020620.xml

doitright · February 18, 2020, 10:48am

Check if the file is there. If it isn’t, figure out why. The wget command is the one responsible for retrieving it.

vishnu.tvrprasad · March 20, 2020, 9:35pm

Do you have the instructions for building the kernel for Dragonboard 410C?
Als are the instructions for building Android same for Dragonboard 410c?

Loic · March 23, 2020, 9:58am

Loic · March 25, 2020, 8:25am

Here are the steps I follow to build aosp:

repo init -u https://android.googlesource.com/platform/manifest -b master
repo sync -j$(nproc) -c

rm -r device/linaro/dragonboard
git clone -b db410c https://android-git.linaro.org/device/linaro/dragonboard410c.git device/linaro/dragonboard

source build/envsetup.sh
lunch db410c
make -j8

Maybe you can also look at this thread fr kernel building: Missing defconfig for Linaro's AOSP port for db410c - #7 by BigCountry907

Loic · March 25, 2020, 8:26am

you need to run

source build/envsetup.sh

before lunch/make.

doitright · March 26, 2020, 11:28am

It has to include “source” as in “source build/envsetup.sh”, or “.” as in “. envsetup.sh” (i.e., “.” followed by <space> followed by “envsetup.sh”), otherwise it WON’T WORK.

doitright · March 26, 2020, 5:37pm

It looks like some people are mixing these instructions with the instructions found here; Building Android Open Source Project (AOSP) for Dragonboard - 96Boards

It is important to understand that trying to follow the instructions at that link will cause a path conflict between the db845c repository and the db410c/db820c repository. In order to follow the “rm, git” instructions, the local manifest must be removed.

Don’t use -j8. That will consume all your RAM and then crash the build. Either leave it out, or use something smaller, like -j2.

vishnu.tvrprasad · March 26, 2020, 6:46pm

Things are working for me and i am able to boot into Android with the steps you have mentioned.
Thank you.
The prebuilt kernel is actually based on the Linux kernel 5.2, where can I find the source code for the prebuilt kernel on which Amit’s patch is based on?
