I recently got a FOMU FPGA board and I couldn't wait to tinker with it! :D

I have build a very simple setup consisting of a minimal NEORV32 SoC, a USB-UART bridge IP and some FIFOs. The result is a FOMU setup that blinks a heart beat on the RGB LED and echos all incoming UART data back to the host - all controlled by a RISC-V core.

If you are curious check out this GitHub discussion for more information (including the setup's sources).
