I was doing some android automotive related stuffs. For that i need to build AAOS for a specific board which doesn't have AAOS support and have android support. So i'm planing to make canges to available android device tree so that it can boot AAOS. The issue is that, I'm not sure about what all changes are needed for automotive.
I have compared a official aaos sources with android source. After adding those changes to my build, it still boots th android
See https://source.android.com/docs/automotive/start/avd/android_virtual_device
Consider to use AAOS emulator build as starting point.
sdk_car_x86_64 build files can be a good reference.
