hi commiunity.
I tested the BPI-M2 Zero board with the android4.4 binary provided on this site and it worked very well. I created the BPI-M2 Zero image using the android7.0 source provided by Allwinner and tested it on the BPI-M2 Zero board. However, the following error occurred:
This is some log message at boot time.

I understand that the BPI-M2 Zero does not support android 7.0 yet , so can not help it now. I would be very grateful if someone could help me with this.
Thank you.
