note : this image is from ubuntu 16.04 for raspberry pi version ,we let it support banana pi. support mali GPU and powerVR gpu function.
I tested that image, on my M2+, system monitor shows only 2 CPU (cores) which is purposed to be 4 cores. I guess that is the bug in software.
It seems only use 2 cores of CPU to run the OS. Please check it.
BT device (Adapter) is not loaded for PI user, maybe for root user, it is activated -- not sure yet.
I also tested Android 4.4 v1 and v2, why only use 2 cores of CPU, let the other 2 cores stopped?
How to make all 4 cores working? is there any boot configuration file I can update?
