Milkymist Labs 
JTAG-Serial programmer
Based on the high-speed FT2232H chip, our JTAG-Serial programmer plugs into a Milkymist board and provides a smooth development experience:
- Configuring the FPGA with the open source UrJTAG tool
- Writing the flash
- Providing a serial console for debugging the device
- Using GDB for live debugging of software running on the board
