Hardware is REALLY scarce right now. See if the solutions I typed (minutes ago) at Latest Availability - #2 by robertlipe help you out.
If you need help moving your project to those emulators (or just want a screenshot of it running on “real” hardware) LMK, but I think the examples are pretty good. Renode is my pick, though I’ve used QEMU in the past.
You could probably test different RISC-V builds (RV32 with FP or emulator), RV64GC, etc. with largely the same virtualized framework.
