As noted here:

  http://mail-index.netbsd.org/port-arm/2016/01/13/msg003605.html

I use the following "uEnv.txt" on my BBG:

bad_dog=mw 44e35048 aaaa; sleep 1; mw 44e35048 5555
uenvcmd=run bad_dog; setenv bootargs root=ld${mmcdev}a; if test $board = am335x; then setenv bootfile netbsd-BEAGLEBONE.ub; setenv loadaddr 82000000; else setenv bootfile netbsd-BEAGLEBOARD.ub; setenv loadaddr 81000000; fi; fatload ${interface} ${mmcdev} ${loadaddr} ${bootfile}; bootm

Note, that I think it requires a MLO/u-boot like the one that comes on
the Debian-8 image.
