When I attempted to use the result of:

/mnt/EFI/BOOT/
the pine64+ boot sequence got over and over

I found an old boot1.efi to copy over instead (from
back in -r308??? time frames as I remember) and
doing the replacement got past this point.
Booting with the non-debug kernel appears to hang for
a bit and then gets to a db> prompt and a bt showed
(for example):
(The console output for the register dump seems
to always be incomplete and there is a wait to
end up at the db> prompt. Note the data_abort
closest to the fork_exit .)

Booting with a debug kernel worked fine. (This matches up
with past reports about "recent" pine64+ handling.)
But trying to have the root file system on a USB SSD
drive failed to see the USB drive at all. (This matches
up with past reports about "recent" pine64+ handling.)
