I followed the instructions from the FreeBSD Beaglebone Wiki to use the
command:
'gpart unset -a active -i 1 mmcsd1'
To force booting FreeBSD Current from the microSD card without pressing the
boot switch. This doesn't work for me. My Beaglbone Black boots OK into
FreeBSD when pressing the switch.
root at beaglebone:/root # gpart show mmcsd0
=> 1 7626751 mmcsd0 MBR (3.6G)

root at beaglebone:/root # gpart show mmcsd1
=> 63 7471041 mmcsd1 MBR (3.6G)

The FreeBSD installation on the microSD card shows active and the onboard
eMMC does not have the active flag displayed. I noticed that the FreeBSD
image starts at sector 1 and the factory image on the eMMC starts at sector
63. Does this make a difference? How can I change this if this is a
problem?
