Any iCE40 8K (or 4K) board, such as the lattice hx8k breakout board, the icoboard, or icezero. Ice40 Up5k boards also work (we recently added support for ice40 UltraPlus to icestorm).

Excellent, thanks! I assume this implies picoRV32 fits in an iCE40?
-
Doesn’t that one only need 300 or so LUTs? A fully featured RV32IMAC is maybe 2000 or so LUTs I think.
-
s/300/750/. And that is on Xilinx 7 series. On Lattice iCE40 it is closer to 1500 minimum size.
-
Hmm I’m sure something uses 300.
@jangray’s cores? -
I think the last number for GRVI that I have seen was 350 LUTs. So that would at least be in the right neighborhood.
-
That’s clearly a very minimal processor. Just RV32I. No atomics, no multiply, no compressed.
-
GRVI does MUL* and LR/SC. No compressed.
