How to build a bootable AOSP10 image files for Hikey970

I had bought a brand new “Hikey970 96Boards consumer edition” development board last month.

Successfully booted AOSP factory images from below URL.

I was planning to add my own custom HMI Applications for the board. In-order to build the custom application I have to build AOSP 10 workspace.

Had used the following steps to build the latest master branch for hikey970.

While building the default AOSP master branch there were lot of errors while building AOSP master branch for hikey970. Modified codebase is as follows


AOSP build was successful and all binaries were generated successfully but the system was not booting when I place system.img.

System was not booting

Is there any fixed steps in building the AOSP10 workspace for hikey970 without modifying the master branch code ?
Could you please confirm whether am I on the right branch?

OR

Could you suggest me the steps to successfully built a bootable collection of images for hikey970?

OR

Could you please suggest me the steps to successfully build an AOSP 10 binaries which can boot into the system without any kernel panics or SYSTEM_AS_ROOT issues?

Thanking you in advance.

If your goal was to run android, you bought the wrong board. Hikey970 has never been well supported for Android, and you invariably end up where you are now. My recommendation for you would be to start with the working upstream support for hikey960 and adapt it to the 970. Alternatively, read your logs and figure out from that what is going wrong and what needs to be changed to make it work.

Thank you very much @doitright.

Could you please recommend me with some reference URLs for enabling my hikey970 board to adhere with hikey960 implementation?

I mentioned that support for the 960 is upstream. Look there. And look at the history for your 970 device repository to see what was done to make it compliant with the 970, since it was based on the upstream 960 – a long time ago.

It is probably not going to be fun when you start addressing the kernel. I think the 960 is running on 5.4 GKI, but you won’t be able to go there with the 970 without a ton of work, however, you should be able to get it working on the existing kernel without too much effort.
