Hi,
I tried to boot VisionFive 2 RISC-V SBC board [1] with a current
OpenBSD snapshot and I got it to boot from a SD card after replacing
the Linux root partition on the image provided by the vendor
with an OpenBSD partition.
I guess it's still early days and that could be why I couldn't find
previous messages or info on the web with dmesg output since is
not super-interesting yet.
Anyway, you can boot bsd.rd but the installer will not be able to
advance after the step where the install disk is selected since
no storage devices are found (no USB devices are detected yet
and I don't have a M2 SSD disk handy to test (to-do)).
See below dmesg output (I'll try to repeat this later with OpenBSD
preinstalled on the SD card to see if I can get further in the boot
process with this board):

I'm also including the output I got from the firmware and u-boot
since I guess it could be interesting to other folks with interest
on this hardware. Also, maybe other folks could be running it with
more recent firmware and better results?
