First of all it seems as if the power adapters I had used with the old Pi’s were not giving out the amperage that the Pi 2 required. Second I’m not sure if I just did not wait long enough after booting, but it seemed to hang during boot so I rewrote the image a couple of times.
Now it gladly boots repeatedly and runs fine. Even completely headless which apparently has not been the case that long with FreeBSD on the Pi 2.
Booting and bootstrapping pkg is the only things I have done with it so far.
A couple of notes, I wrote a 10.2-STABLE image for the original Raspberry Pi on the card and got the rainbow screen so that seems to be a good indicator of issues with the image or SD card. Also, FreeBSD turns the power diode off during boot, so using that to gauge if it booted properly in headless while trying out various images was not that good an indicator..
