This is an independent report from the exchange
with Bob P. about his overall problems. This has
its own subject text. There is not much to this
specific report. Messages with other subjects
should be ignored for this issue. USB media is
not involved here: a microsd card is sufficient
to see the problem.

No clue for your distinction. But, being serial console
based until ssh is possible for my context, I classify
serial-console-broken as a booting issue. (For example,
not being able to identify the DHCP address assigned
if it did make it that far.)

It may be that the snapshots need to be modified to deal
with EFI loader changes --instead of changes to the loader
needing to be made. I'm not trying to specify which.

The images listed in the above are the official snapshots.
I've no way to be more explicit than the file names of the
official snaphot images. The use of 20220930 (date) instead
of 20221007 for main's snapshot was an accident and I could
try the one with the more recent date if needed.

If you have RPi2B v1.1 (so: armv7) access, just try to boot:

FreeBSD-14.0-CURRENT-arm-armv7-GENERICSD-20220930-42dc8696df5-258315.img

via serial console usage, no video connection present. (I
did not try a video connection as that is not my type of
context.)

To make it work for that context, replace the EFI/BOOT/bootarm.efi
by the one from:

FreeBSD-13.1-STABLE-arm-armv7-GENERICSD-20221007-d497b97e902-252653.img

and then retry booting the result.
