The VisionFive 2 is a RISC-V based single board computer from Starfive
integrating their JH7110 SoC. The board is available from Waveshare on its own
or with some handy components to get you started.
The SoC is pitched to be a competitor to the RaspberryPi 4 in specs and along
with oodles of interfaces it has a raspberrypi compatible 40 pin header
exposing pins for io.
The SoC is also in the
Star64
and
PinetabV
from
Pine64 (I didn't know that the StarFive was for sale until checking when
writing this).
StarFive is a Chinese integrator using IP blocks from SiFive and so it
integrates cores and peripherals from the HiFive Unleashed board.
I picked one of these up to play with FreeBSD/RISC-V on a computer with a real
MMU. Before doing anything I wanted to be sure that I could get Linux to boot
on the board. I sort of followed the instructions from the [Waveshare wiki
page][wavesharewiki], ignoring the Windows GUI tools and using
dd
and
cu
to
write the image and connect to serial.
With an SD card image with their published I powered up the board and tried to
connect. The wiki instructions highlight that you need to break into the boot
loader during boot and manually load segments from the SD card. I tried this
for about an hour or two with 3 different images (the 69 image took 40 minutes
to write to the SD card), but I didn't have any luck.
Giving up I just let the u-boot run and got a booting Debian system
immediately:

With that working it was time to try FreeBSD. A little searching unearthed a
forums post
showing a success
opensbi->u-boot->loader
process, but
almost immediate failure once the kernel started. The forums post used a stock
13 image to boot which made it look like getting to a partially booting kernel
wouldn't require too much extra work even if there was an immediate boot issue
to fix.
The Debian boot process initially recommended manually picking up the kernel
and device tree images to boot. A little googling pulled up a
git repo with a
script and instructions on how to boot
. With that magic I grabbed a
current snapshot and tried to reproduce the failing boot.

Cool, I can reproduce the failure. I love it when that happens.
The git repo I got the u-boot commands from was adding a memory disk image to
the boot process and showed a system log of the host getting all the way up to
single user (without any device specific devices discovered). Digging into
their script they pull down a different device tree blob and use that with
their manual u-boot boot.
There was a follow up post by Jess (jrtc27@) linking to a
issue with the
device tree blob
. I guess her suggestions were merged into the
visionfive2 tree and they have yet to make it through Linux and into FreeBSD.
We need an updated DTB.

Cool that works, but it is a very annoying way to boot. Can we fix it?

Environment size: 7216/65532 bytes
From the u-boot environment we can find the DTB file u-boot is passing on to
the EFI loader. If we move our DTB to be in that location on disk we should be
able to boot automatically.
fdtfile=starfive/starfive_visionfive2.dtb
With the working DTB in the correct place we can boot the FreeBSD image from
power on without any manual intervention. We fail at mount root because we are
missing drivers for any sort of storage medium, eMMC or SD (both are on a SDIO
controller), USB or NVMe. We don't have any drivers for this board yet, the
stuff detected in the dmesg above is devices in the DTB which exist elsewhere
and so have FreeBSD drivers.
To get past mount root (without using a memory disk) we need to have a
storage driver, so lets pull up the docs and write one!
Much angered reading and intense searching later
It looks like there isn't useful documentation available for a driver writer.
There are open source drivers on their way into the Linux Kernel, but the
Software TRM is a high level overview, the software developer guides explain
how to use interfaces from Linux and everything else is a useless summary.
From searching I found that
Haiku is booting and running on the
VisionFive2
. They have drivers for the PCIe controller giving them USB
and NVMe and graphics on the frame buffer because u-boot is kind enough to set
it up. As far as I can tell (I hope I'm wrong), they PCIe controller driver has
been cribbed from the Linux Kernel.
While writing drivers from others source is possible, it is a bit hairy going
from the GPL to BSD licenses and it is terribly annoying when you hit issues to
not have documentation.
I can't see FreeBSD supporting the VisionFive2 without there being proper open
documentation to write drivers from.
