You're holding down the wrong button. :-)  You need to hold down the user boot switch at the other end, near the micro SD card.  See https://wiki.freebsd.org/FreeBSD/arm/BeagleBoneBlack for details.  (See http://learn.adafruit.com/system/assets/assets/000/008/680/original/BeagleBoneBlack.jpeg?1369065340 for location of button.)

BTW, is it possible to put a boot loader on the eMMC so that it will always try and boot FreeBSD from the micro SD card?  Alternatively, is it possible to make the FreeBSD boot loader/layout on the BeagleBone Black compatible with the Angstrom boot loader?  It appears to look for an ext2 file system if the micro SD card is present.  Would a BeagleBone Black image that uses ext2 be bootable by the resident Angstrom system?

Cheers,

Paul.
