Took me a couple of days to find out that the how-to about flashing Android to the eMMC of my new M64 won't work with Windows 10 but Windows 7 and that I would need to select the driver(s) manually from the PhoenixSuit directory (which does not seem to be documented anywhere). However: With Win7 and manually applying the drivers thing it worked now ---> yay!
The latest Android build now runs fine
The main purpose to run Android is to be able to use screen cast aka. screen mirroring aka. wireless display.
From my CyanogenMOD Galaxy S5 I don't see any available devices from my Samsung smartphone even though I got "Enable wireless display" ticked in the settings of the Android at the the BananaPi M64 (Settings --> Display --> Cast). It works fine from my smartphone with other devices though.
Any idea what needs to be done to make this work?
