Note: then make sure you have your network cable connected to it. Afterwards, power it up. Be very patient. It takes a few minutes to see it on your network. I usually do
ping 192.168.2.79

after doing this, I shutdown:
sudo shutdown -h now
And all the SBC’s lights are off almost instantly. Please enable the custom repo for the latest daily ubuntu server kernel builds provided by our superhero @agreenbhm are magical Thank you again. Can’t praise enough.
As @larryw3i mentioned, check your boot mode settings Boot Mode Settings and bootloader. I get that error when the the bootloader doesn’t load.
(edit: added everything below after new user restrictions were lifted)
Yes, I literally all I get is (no u-boot messages):
dwmci_s: Response Timeout.
BOOT fail,Error is 0xffffffff
The specific error line can occur in other places too so if you get more output it might be helpful to mention that.
In my case the board seemed to have an issue with the SPI stored bootloader with literally nothing booting (at the time I hadn’t uart connected so don’t have exact messages).
The fix was to switch from SPI to SDIO/SD (from both dip switches on the right to bottom to left) which then get the sdcard.img (part of the VisionFive release e.g. https://github.com/starfive-tech/VisionFive2/releases/download/VF2_v3.0.4/sdcard.img ).
After that I followed the boot loader upgrade instructions as per Updating SPL and U-Boot of Flash then changing the dip switches back to use SPI flash (both in right position).
The reason the sdcard.img boots is due to its specific layout (its intended for flashing after all):

My second attempt to get my VF2 working I had a good solid USB Type C PD power supply (30W 2A@15V) but I chose to use a really old MicroSD card I had laying around, which turned out not to work…
Samsung 16GB UHS-I Grade 1 MicroSDHC Class 10
It would load the SPI+U-Boot partition fine and the U-Boot+OpenSBI partition fine, but partition 3 was always invalid.
Ultimately the error message seen just before this was “Card did not respond to voltage select! : -110”. So it was like during the boot process the voltages were being changed and then the VF2 could no longer read the MicroSD card.
I ended up buying a new MicroSD card and everything worked fine after that.
I also saw the below error messages on my first attempt to powerup my VF2 when I used 5V to power the board, from a bench power supply connected to the two +5 V GPIO pins and two Ground pins (to help reduce the maximum current on each individual pin). The wires used were not the best so I was probably suffering a large voltage drop across them. The allowed voltage range for USB 2.0 High Speed is 4.75V to 5.25V, so I slowly raised my bench power supply to 5.25 volts and those error messages vanished at about 5.15 volts. And that was when I started to see problems with my MicroSD card.
