Berkeley has done 11+ tape-outs of RISC-V chips. LowRISC is looking to do a silicon run in a year-ish, and there's already one company that's publicly stated they've already been shipping RISC-V cores in their cameras.
We have taped out several chips for our own research. But as a university research lab, we do not have any plans for a commercial manufacturing run. The lowRISC team can say more about the roadmap to a commercial dev board.
