beaglebone black hdmi micro-HDMI video output

[Robert Crowston]

AFAIK micro-HDMI is no different from regular HDMI, just a smaller connector.

HDMI may work on the other Beagleboard models, but that could be due to a different chip rather than the connector.

If there's no output at all, that sounds like a problem with the bootloader.

Have you tried booting without the serial connection -- it may be the bootloader will only attach to one output. That's a pure guess though.

Do you get any feedback on the serial port describing the display configuration in the bootloader?

You could also try forcing freebsd to use the console as well as the serial port with the -D option, but I suspect if the bootloader didn't detect and configure video out, neither will the kernel.
