The rpi image is based on core-image-minimal 

Kernel:

Image file

wic file need to be flashed to sdcard using dd command or your favorite tools like rufus
Image file: <path-to-src>/build/tmp/deploy/images/rpi3/rpi3-image-rpi3.wic

Next steps/TODO:

Building Headunit is ok
Fine tune kernel recipie, implemented in hurry.. hahahah
Next test it on device, if some problem fix them
Next Project/learning: understand how Andorid Auto protocol is working from the source code
