I just installed the package:
[72]cicely7# pkg info | grep rock
u-boot-rockpro64-2019.10       Cross-build das u-boot for model rockpro64
[73]cicely7# uname -a
FreeBSD cicely7.cicely.de 12.0-STABLE FreeBSD 12.0-STABLE r343219 GENERIC  amd64
[74]cicely7# ls /usr/local/share/u-boot/u-boot-rockpro64
README          idbloader.img   u-boot.itb

Since I also see garbled output with two different CH340G adapters at 1.5Mbps,
as well as a PL2303, I assume there is something fishy.
I will see what happens with the anlyzer.

I agree, since many adapters arn't capable of doing 1.5Mbps.
Not to mention the byte losses.
