I do not know if the FreeBSD kernel has been depending
on some U-Boot initialization for root-on-USB and the
two no longer match or what.
But I've used a release/13.0.0.0 microsd card based
boot to get older U-Boot materials (Quarterly as it
turns out). Installing such got me back to having a
root-on-USB boot of the OPi+2e (other than the
mircosd card having the older U-Boot (2020.10 as it
turns out). Of course there is also the matching
boot.scr involved --but it also is on the USB SSD.
(Similarly reverted RPi2 U-Boot, other than needing
to switch boot.scr to match.)
After booting with the reverted U-Boot related
material:
# mount -onoatime -tmsdosfs /dev/mmcsd1s1 /mnt
# mount -onoatime /dev/mmcsd1s2a /media
# ls -Tla /mnt/
total 20
drwxr-xr-x 1 root wheel 16384 Dec 31 16:00:00 1979 .
drwxr-xr-x 25 root wheel 512 Dec 31 16:00:40 2009 ..
# ls -Tla /media/
total 60
drwxr-xr-x 2 root wheel 512 May 24 15:43:19 2021 .
drwxr-xr-x 25 root wheel 512 Dec 31 16:00:40 2009 ..
-rwxr-xr-x 1 root wheel 52456 Apr 24 19:48:36 2021 bootcode.bin
The media is also set up for booting an RPi2 via
root-in-USB ( other than bootcode.bin ).
If FreeBSD and the more modern U-Boot were well matched
for USB support, I'd expect that this sort of thing would
work (no boot.scr needed).
