I just realized that your original message said:

"Just tried the latest FreeBSD on RPI image on my rpi4-4GB system."

There is no such image for the RPi4. Looking at:

=
https://lists.freebsd.org/pipermail/freebsd-snapshots/2020-May/000698.html=


shows:

o 13.0-CURRENT aarch64 GENERIC
o 13.0-CURRENT aarch64 RPI3
o 13.0-CURRENT aarch64 PINE64
o 13.0-CURRENT aarch64 PINE64-LTS
o 13.0-CURRENT aarch64 PINEBOOK
o 13.0-CURRENT aarch64 ROCK64
o 13.0-CURRENT aarch64 ROCKPRO64

Treating an RPi4 as a RPi3 is not going to
make everything work: it does not have
the right variant of u-boot, for example.

The following lists installed files from ports:

sysutils/u-boot-rpi[34]
sysutils/rpi-firmware

The installations of the 2 prots only puts the files
someplace so they (or some) can later be copied to the
msdos file system involved.

# ls -ldT /usr/local/share/u-boot/u-boot-rpi[34]/*
-rw-r--r--  1 root  wheel     124 Apr 25 00:16:57 2020 =
/usr/local/share/u-boot/u-boot-rpi3/README
-rw-r--r--  1 root  wheel      37 Apr 25 00:16:55 2020 =
/usr/local/share/u-boot/u-boot-rpi3/metadata
-rw-r--r--  1 root  wheel  499824 Apr 25 00:16:54 2020 =
/usr/local/share/u-boot/u-boot-rpi3/u-boot.bin
-rw-r--r--  1 root  wheel     124 Apr 25 13:28:34 2020 =
/usr/local/share/u-boot/u-boot-rpi4/README
-rw-r--r--  1 root  wheel      37 Apr 25 13:28:34 2020 =
/usr/local/share/u-boot/u-boot-rpi4/metadata
-rw-r--r--  1 root  wheel  506360 Apr 25 13:28:34 2020 =
/usr/local/share/u-boot/u-boot-rpi4/u-boot.bin

If you replaced the u-boot.bin in the msdos file system
with the rpi4 one the memory might well show correctly.

There is also:

# ls -ldT /usr/local/share/rpi-firmware/*
. . .
-rw-r--r--  1 root  wheel        89 Jan 30 13:26:19 2020 =
/usr/local/share/rpi-firmware/config.txt
-rw-r--r--  1 root  wheel       147 Jan 30 13:26:19 2020 =
/usr/local/share/rpi-firmware/config_rpi3.txt
-rw-r--r--  1 root  wheel       135 Jan 30 13:26:20 2020 =
/usr/local/share/rpi-firmware/config_rpi4.txt
-rw-r--r--  1 root  wheel       110 Jan 30 13:26:19 2020 =
/usr/local/share/rpi-firmware/config_rpi_0_w.txt
. . .

where you would need to copy the config_rpi4.txt content
to the config.txt in use on the msdos file system.

There are other files for the RPi4 from the list as well.
I've not checked a rpi3 snapshot do know if the snapshot
has copies of RPi4 specific files:

-rw-r--r--  1 root  wheel      5888 Jan 30 13:26:31 2020 =
/usr/local/share/rpi-firmware/armstub8-gic.bin
-rw-r--r--  1 root  wheel     40659 Nov 22 09:06:45 2019 =
/usr/local/share/rpi-firmware/bcm2711-rpi-4-b.dtb
-rw-r--r--  1 root  wheel      6193 Nov 22 09:06:45 2019 =
/usr/local/share/rpi-firmware/fixup4.dat
-rw-r--r--  1 root  wheel      3089 Nov 22 09:06:45 2019 =
/usr/local/share/rpi-firmware/fixup4cd.dat
-rw-r--r--  1 root  wheel      9181 Nov 22 09:06:45 2019 =
/usr/local/share/rpi-firmware/fixup4db.dat
-rw-r--r--  1 root  wheel      9183 Nov 22 09:06:45 2019 =
/usr/local/share/rpi-firmware/fixup4x.dat
-rw-r--r--  1 root  wheel   2775076 Nov 22 09:06:45 2019 =
/usr/local/share/rpi-firmware/start4.elf
-rw-r--r--  1 root  wheel    775872 Nov 22 09:06:45 2019 =
/usr/local/share/rpi-firmware/start4cd.elf
-rw-r--r--  1 root  wheel   4582664 Nov 22 09:06:45 2019 =
/usr/local/share/rpi-firmware/start4db.elf
-rw-r--r--  1 root  wheel   3536680 Nov 22 09:06:45 2019 =
/usr/local/share/rpi-firmware/start4x.elf

in the msdosfs file system.

Note (where config.txt is a copy/variant of
config_rpi4.txt by content):

# more /boot/efi/config.txt=20
arm_control=3D0x200
arm_64bit=3D1
dtoverlay=3Ddisable-bt
dtoverlay=3Dmmc
device_tree_address=3D0x4000
kernel=3Du-boot.bin
armstub=3Darmstub8-gic.bin

So, without armstub8-gic.bin being present
in the msdos file system, the RPi4 config.txt
content would then specify a missing file.
Similarly for u-boot.bin .
