I'm having exactly the same problem. I was trying to backtrace the problem and found something is going wrong at riscv-pk/machine/minit.c line #27 with the old vanilla branch. The statement makes u500 to print something but at the end it hangs at do_tohost_fromhost where you cannot escape the infinite loop. Don't know the reason.
+ for the new freedom-u-sdk, it hangs at riscv-pk/machine/mentry.S line# 277. It is waiting for the interrupt but it never happens. Mine doesn't have pcie so I might be getting the error for a different reason.

I too am having the same issue although I am trying to boot with out the FMC PCI board. I have made changes accordingly to work without the FMC but I get stuck at the same state as the above prints. I kept doubting my changes (as there was no way for me to test the base code) however thanks to this post I think there might be some issue with base SiFive code.

@palmer-dabbelt @henrystyles Is the freedom-u-sdk/master in-sync with the (very old) vc707 image on our site? We should probably also provide a newer vc707 image compatible with the latest (hopefully final) revision of the privileged spec...

Ya, we need to bump everything. If freedom/master is updated then I can go deal with the software.

I think the main effort required is to create a new VC707 image using only open-source stuff.

I am unable to get work done for nearly a month now because of this issue. Happy to build the images myself, but unclear which freedom-u-sdk
is compatible with recent commits to freedom
.
Is there a specific freedom-u-sdk
commit that is known to boot on 22ee433 in freedom
? If not, perhaps a specific earlier earlier commit to freedom
? Trying pairs until a working one is found is extremely time consuming and a huge waste of time if somoene on this list knows the answer.. Surely someone here knows the answer.
Any info would help here, thanks,
from freedom.
freedom/master should work with freedom-u-sdk/master now. Furthermore, we are preparing an updated freedom-u-sdk which should better support FPGAs.

Hi @terpstra, thanks for the update.
A small correction, in case anyone is stuck: freedom/master
successfully boots with freedom-u-sdk/priv-1.10
. (/new
immediately panics, and /master
has seen no updates and exhibits the same opaque failure to boot).
