yocto project used beaglebone black as one of its reference boards
so you can find a default reference yocto BSP for it.

Secondly, meta-ti is TI BSP layer which also supports beaglebone black
since the board is from TI

you can use git clone git://git.yoctoproject.org/poky -b pyro
for getting latest stable release.

I would suggest to do a bit more investigation as to what you need.
meanwhile you can build yocto reference BSP and play with it. There
are many packages that meta-ti would have that you might need depending
upon what you plan to do.
