Home UI not fully shown followed by reset on AOSP14 QPR2 Android Automotive

[Samaelson]

Hello,

with latest car build I observe the issue, that home UI comes up with black background and some submenus not working/shown.

After a while rpi5 runs a reset and reboots.

Anyone else having that issue?

I have just built and tested out android-14.0.0_r30 with aosp_rpi5_car-ap1a-userdebug (AAOS) on Raspberry Pi 5. I am seeing similar behavior: boot animation completes fine, some System UI is shown, parts of the CarLauncher are seen, but incomplete. No apps can be started, but pi reacts fine to things like climate menu. After a minute or so it reboots on its own.

@Samaelson the logs you got are not logcat. I believe we need logcat logs to see what keeps crashing on Java side and causes the reboot.

I have tried to connect to Pi via USB-A to USB-A cable, but do not see it under adb devices even when it's "booted". Looking at other issues, it seems like we need to use UART to get logcat. I only have standard UART adapters with dupont cables, however Pi5 has this weird 3-pin connector, which I have just ordered. So it will take me some time until I can look at it.

In the meantime, @KonstaT, maybe you have a guess on what is missing? Are we doing something wrong, or was aosp_rpi5_car-ap1a-userdebug version simply never tested with android-14.0.0_r30 and we're the first to try?

Maybe try adding <bool name="audioUseDynamicRouting">false</bool> to device/brcm/rpi5/overlay/CarServiceRpiOverlay/res/values/config.xml? Seems like audio zones are not defined/initialized properly, so my guess would be to disable them completely as a first step.

You can revert https://github.com/raspberry-vanilla/android_device_brcm_rpi5/commit/71b154a8bb0facac24c8a27a0bfff93d3fe1aaf5 if you want to move the serial console to GPIO14/15. USB-A ports on Raspberry Pi are host mode only so it's not even technically possible to use ADB on those. You can use ADB on the USB-C port if you have outside power source (powered USB-C hub, 5V on the GPIO, etc).

No, I haven't tested all build variants on all tags and all devices. tv and car build targets are just side products of the tablet configuration as what AOSP is offering on these build targets doesn't provide much use outside development purposes.

I would assume Android Automotive is working on android-14.0.0_r22 because of https://github.com/raspberry-vanilla/android_local_manifest/issues/33. AOSP14 QPR2 caused all kinds of mayhem so android-14.0.0_r22 is branched out in a separate manifest. https://github.com/raspberry-vanilla/android_local_manifest/tree/android-14.0.0_r22

As for the issue itself, it looks like it's required to implement automotive audio control HAL and occupant audio zones (if using legacy routing policy doesn't solve this).

@khvMX : Tried your approach with setting audioUseDynamicRouting to false, but unfortunately it's not working. Is it working at yours?

[khvMX]

I have tried it and saw no difference in behavior. Unfortunately, I still could not get to logcat, so I did not proceed with debugging. I would expect that with this change it would trip elsewhere. I'm building the android-14.0.0_r22 now. Note that you need to use instructions from this specific README.md

[khvMX]

I can confirm that android-14.0.0_r22 is booting fine:

Thanks for update @khvMX . i tried with android-14.0.0_r34 branch but its not booting. when i am trying to switch the branch to android-14.0.0_r2( repo init -u https://android.googlesource.com/platform/manifest -b android-14.0.0_r22 --depth=1) i am getting manifest default.xml not avaliable.

here is the complete log of swithching the branch: ramesh@ramesh: repo init -u https://android.googlesource.com/platform/manifest -b android-14.0.0_r22 --depth=1 repo: reusing existing repo client checkout in /home/manyantan/aosp14 fatal: manifest 'default.xml' not available fatal: remove-project element specifies non-existent project: Repo command failed: UpdateManifestError Unable to sync manifest default.xml

any help woule be appreciated

Thanks

@ramesh-m99 to avoid all sort of weird unexpected issues, I usually start from scratch in another directory. For instance, I started with ~/aosp/rpi-android-14.0.0_r34/, and after that I created ~/aosp/rpi-android-14.0.0_r22/ where I'd execute repo init -u https://android.googlesource.com/platform/manifest -b android-14.0.0_r22 --depth=1 followed by instructions from this README. Take care not to run out of space, at least remove ~/aosp/rpi-android-14.0.0_r34/out, or whole ~/aosp/rpi-android-14.0.0_r34/ directory.

@khvMX : Based on the diff of CarAudioService.java (r22<->r34) may be flag name changed and your proposed

"audioUseDynamicRouting" set to "false" does not fit any more for r34?

[Samaelson]

runInLegacyMode obviously depends on mUseDynamicRouting and mUseCoreAudioRouting

runInLegacyMode() was removed in >=r38.... obviously this change was turned back and runInLegacyMode only existed r29 to r37
