See OpenFutNet, Firmware Tools Comparison and recovery boot.

If you want to use USB connection to write an FPGA bitestream you can use OpenFutNet.

For instance, a full quality control test already performed at Trenz Electronic laboratory premises requires all the following steps to be performed:

  1. Cypress USB generic device driver installation;
  2. USB FX2 microcontroller large EEPROM programming;
  3. specific USB device driver installation;

  4. an *.iic file generation/download;

  5. a firmware upgrade tool (Cypress tools: CyConsole or CyControlCenter TE tools: OpenFut, OpenFutNet or FX2EEPROMProgrammer) utilization.

  6. reference bitstream file written on SPI Flash  ?????Flash
