I dd'd FreeBSD-13.0-RELEASE-arm64-aarch64-ROCK64.img to
a microsd card and booted it (no eMMC or USB storage
attached). This created .185 instead of the .149 for
networking:

--- 192.168.1.185 ping statistics ---
102 packets transmitted, 102 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.126/0.198/1.925/0.244 ms

--- 192.168.1.120 ping statistics ---
102 packets transmitted, 102 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.175/0.206/0.629/0.044 ms

(.120 is a ThreadRipper 1950X.)

Consistent with the past, it appears that various Rock64 v2.0's
may not be equivalent. At least for my context,
FreeBSD-13.0-RELEASE-arm64-aarch64-ROCK64.img of itself does not
seem to be a problem for the Rock64 v2.0 that I have access to.
That spans U-Boot and FreeBSD being the same as you tried.
