Installing USB Drivers

To program Titanium™ FPGAs using the Efinity® software and programming cables, you need to install drivers.

Efinix development board has FT4232H FTDI chip 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.

Installing Drivers on Windows

On Windows, you use software from Zadig to install drivers. Download the Zadig software (version 2.7 or later) from zadig.akeo.ie. (You do not need to install it; simply run the downloaded executable.)

Install the driver for the interfaces listed in the following table.
Board Interface to Install Driver
Titanium Ti375 C529 Development Board Install drivers for interfaces (0 and 1)

To install the driver:

  1. Connect the board to your computer with the appropriate cable and power it up.
  2. Run the Zadig software.
    Note: To ensure that the USB driver is persistent across user sessions, run the Zadig software as administrator.
  3. Choose Options > List All Devices.
  4. Repeat the following steps for each interface. The interface names end with (Interface N), where N is the channel number.
    • Select libusb-win32 in the Driver drop-down list.
    • Click Replace Driver.
  5. Close the Zadig software.
Note: This section describes the instruction to install the libusb-win32 driver for each interface separately. If you have previously installed a composite driver or installed using libusbK drivers, you do not need to update or reinstall the driver. They should continue to work correctly.

Installing Drivers on Linux

The following instructions explain how to install a USB driver for Linux operating systems.

  1. Disconnect your board from your computer.
  2. In a terminal, use these commands:
    > sudo <installation directory>/bin/install_usb_driver.sh
> sudo udevadm control --reload-rules
> sudo udevadm trigger
Note: If your board was connected to your computer before you executed these commands, you need to disconnect it, then re-connect it.
