freebsd on the bbb

hi all
have had a devil of a tine writing a freeBSD img to an SD card for the BBB.
as a result i have tried miserably writing from a VM - to try and compile an image.
Most of my reference material is a year or so older, any one had luck with:
a writing a freeBSD img to an SD card for the BBB
b compiling their own img.

I’d really like to make a minimal freeBSD img for the BBB and go from there.
Anyone had any luck?
