Appendix: Installing USB Drivers
To program Trion®, Topaz, and Titanium FPGAs using the Efinity® software and programming cables, you need to install drivers.
Efinix development boards have FTDI chips (FT232H, FT2232H, or FT4232H) to communicate with the USB port and other interfaces such as SPI, JTAG, or UART. Refer to the Efinix development kit user guide for details on installing drivers for the development board.
Note: If you are using more than one Efinix development board, you must
manage drivers accordingly. Refer to AN 050: Managing Windows Drivers for more
information.
Notice: The Trion
T8 BGA81 Development Boards do not have FTDI chip for USB communication. Refer to
the T8 BGA81 Development Kit User Guide for more information about installing its
Windows USB driver.
For your own development board, Efinix suggests using the FTDI Chip FT2232H or FT4232H Mini Modules for JTAG programming Trion®, Topaz, and Titanium FPGAs. (You can use any JTAG cable for JTAG functions other than programming.)
Note: Efinix does
not recommend the FTDI Chip C232HM-DDHSL-0 programming cable due to the
possibility of the FPGA not being recognized or the potential for programming
failures.
