When I used pre-compiled system.img and other required images on Hikey board.

which are shared from the below path.
https://builds.96boards.org/releases/hikey/linaro/aosp/latest/

I am using below HDMI display and could see android display comes up with the pre compiled images(looks like lollipop AOSP version).

However when I built the latest AOSP code, with generated images.

I have flashed those on Hikey board with same setup above. 

And could not see the display is coming up.

It may be some issue with the display configuration on latest AOSP built,
Got this log from logcat not sure it is expecting built in display rather than HDMI display?

AOSP seem to have booted up fine on Hikey. See
"SystemBroadcastReceiver: Boot has been completed" in your logcat.

Did you try connecting hikey to any other HDMI display?
