Andrew Black hijacks Digilent’s $90 Arty Dev Board and places a RISC-V open-source μC inside the board’s Artix-7 FPGA

The RISC-V open-source processor has a growing ecosystem and user community so it’s not surprising that someone would want to put one of these processors into a low-cost FPGA like a Xilinx Artix-7 device. And what could be easier than doing so using an existing low-cost dev board? Cue Digilent’s Arty Dev Board, currently on sale for $89.99 here. Normally, you’d find a copy of the Xilinx MicroBlaze soft RISC processor core inside of Arty’s Artix-7 FPGA but a SiFive Freedom E310 microcontroller platform that combines a RISC-V processor with peripherals seems to fit just fine so that’s just what Andrew Black has done using the no-cost Xilinx Vivado HL WebPack Edition to compile the HDL.

With Black’s step-by-step instructions based on SiFive's "Freedom E300 Arty FPGA Dev Kit Getting Started Guide", you can do the same pretty easily. (See “Build an open source MCU and program it with Arduino.”)
