Gave 7.2.0 a go yesterday afternoon.
The URL from the documentation is no longer accessible, I cannot wget
the image! I'll try and find out what happened there, AFAIU that FTP is
still in use, so dunno why that file doesn't seem to be there.
I'll try to find out.

I dug out the commit from the docs for the HSS, built that. Generated a
payload using the nearest payload generator commit to that was
compilable, which I passed as the image instead of the wic.

The HSS would load, get as far as trying to extract the payload
containing the next stage bootloader & fail. Specifically, it was
complaining that the magic number for the payload was all zeros.

Perhaps if you still have the original wic image you'll have more luck!

Thanks,
Conor.

btw, I built my QEMU with `./configure --target-list=riscv64-softmmu &&
make`, and got a complaint from the above command that user mode NICs
were not present in my QEMU.
