Android Support for Beagleboard black wireless board


i want to build android (6 or 7) for Beagleboard black wireless board .
can somebody guide me from where to download AOSP source for this board and the build steps .

i asked this because of below 2 reasons ::
a) On beagleboard website , it is mentioned 3rd party support for android . but i could not find any information regarding download of 3rd party android source code and build .
b) On this forum , in discussions , it is suggested to refer to .
however board support matrix shows BBB . is BBB wireless board also supported ? will BBB images work with BBB wireless board also ?

I was able to insert OS to my BBBW, but the wifi is not enable, i’m fighting with that right now.

Any updates on this?
