I'm newer to AOSP building, but now have successfully built various AOSP build configurations, but never been able to boot a built image. I'm on macOS (BigSur). Any insights/gotchas would be super helpful.

I mainly use a M1 mac (aarm64), but have also tried on an Intel (x86_64), tried multiple image builds on each, but same result - black screen on boot. ADB show the emulator as offline once launched so it doesn't seem to be specific to a graphical issue more likely a boot.

What I have tried the following builds:

  • aosp_x86_64-userdebug
  • aosp_x86_64-eng
  • aosp_arm64-eng
  • sdk_phone_arm64-userdebug
  • aosp_tv_arm64-eng

Branches:

  • mainline
  • android11_r37

Machines/architectures

  • macOS BigSur, M1 (aarm64) 16GB
  • macOS BigSur, Intel (x86_64) 32GB

Building AOSP is not a problem, except when it comes to the M1 and needing the 11.x MacOSSDK. I was able to patch the build in necessary places to build to completion - this is all in build/soong so it's not the actual AOSP code needing a change.

I have also tried various GPU options when launching the emulator in case of graphical rendering issues. There's some hiccups with CoreAudio not initializing on the M1 Mac, but disabling audio (-noaudio) gets around this.

As far as I can tell nothing is wrong from using -debug-init and -verbose emulator flags. All the image files are there, as far as I can tell

Here's the log of the latest M1 build using aosp_tv_arm64-eng:

Any insight into why I'm not getting the emulator to boot the image?

Hi,

You can check "lunch target" is supporting that particular branch. 

  • aosp_x86_64-userdebug
  • aosp_x86_64-eng
  • aosp_arm64-eng
  • sdk_phone_arm64-userdebug
  • aosp_tv_arm64-eng

Check these target supported by below branches.
  • mainline
  • android11_r37

If not, then you have build aosp for supported target.
