The target board for the minion-v0.4 release is Nexys-4DDR. We had to cut out some
optional features for this board. Unfortunately the next low cost board in the same
series, the Nexys-Video, lacks flow control on its UART, which causes problems for the
trace debugger. Our build system in principle supports SMP rocket systems that share
L2-cache and DDR memory, coherence is managed by TileLink. I don't think anybody has
built it for FPGA recently.

Hi guys,
may I add a question to the one below:
3) I know it has mentioned a few months ago, but what would be the target virtex eval
board for the next lowrisc release. maybe Wei mentioned it (and the questions below) at
the WS, but the sound is terrible.
thank you for your answer in adcance, see you in Hebden Bridge, cheers, Tobias
