This repository is intended to create cables for programming Efinix FPGAs for which no official download cables exist.
Efinix recommends using FTDI's USB serial IC to create a download cable.
However, since FTDI's default USB VID/PID is used and the driver is replaced, other FTDI devices will become inoperable.
To solve this problem, I will provide a download cable creation method and a corresponding patch for the FPGA programmer software.
This website is in Japanese, but more information can be found here.
