Firmware tool comparison chart

⁽¹⁾ Generation 2 Firmware Upgrade: it requires DEWESoft device driver (VID/PID:0x0547/0x1002) and DEWESoft API.

⁽²⁾ Generation 3 Firmware Upgrade: it requires TE USB FX2 device driver (VID/PID:0x0BD0/0x0300) and TE API (C++ TE_USB_FX2_CyAPI.dll or .NET TE_USB_FX2_CyUSB.dll).

⁽³⁾ Firmware Recovery: it requires USB generic Cypress device driver, to boot with EEPROM disabled and to enable EEPROM after TE USB FX2 module is inserted into USB port. This is the procedure followed by Recovery Boot (TE USB FX2 Firmware Recovery) (CyConsole and CyControl) and Recovery Procedure (OpenFutNet).

⁽⁴⁾ You can use Recovery Procedure to program the USB FX2 microcontroller's  EEPROM with the Generation 3 Firmware required by Firmware Upgrade and FPGA Configuration.

⁽⁵⁾ Based on simplified TE_USB_FX2_CyAPI.dll

⁽⁶⁾ Based on both CyUSB.dll and TE_USB_FX2_CyUSB.dll

⁽⁷⁾ Based on CyUSB.dll

⁽⁸⁾ Version ≥ 2.0

⁽⁹⁾ Version≥ 4.0.30319)

Is Reference Firmware required?

The following firmware tools

• DEWESoft FUT (firmware upgrade tool)
• Open_FUT for generation 2 (Firmware Upgrade and FPGA Configuration)
• Open_FUT for generation 3 (Firmware Upgrade and FPGA Configuration using a simplified TE_USB_FX2_CyAPI.dll)
• OpenFutNet (generation 3, Firmware Upgrade  and FPGA Configuration are using both CyUSB.dll and TE_USB_FX2_CyUSB.dll )

work only if the reference firmware, or a derived firmware, is running in the module. The reference/derived firmware is necessary because the three tools make use of TE API Commands (see the corresponding API reference manual) executed by the USB FX2 microcontroller. These tools are therefore able to update the firmware (EEPROM programming) of the USB FX2 microcontroller and the FPGA configuration file (bitstream, SPI Flash programming).

Note: some TE API Commands require support from a Xilinx MicroBlaze soft embedded processor (of the TE reference/derived architecture), but this TE API Commands are not needed for EEPROM and SPI Flash programming.

The following firmware tools

• Cypress USB Console (Recovery Boot (TE USB FX2 Firmware Recovery) uses CyAPI.lib)
• Cypress USB Control Center (Recovery Boot (TE USB FX2 Firmware Recovery) uses CyUSB.dll)
• OpenFutNet (Recovery Boot uses CyUSB.dll)

work also if the reference firmware, or a derived firmware, is not running in the module. The reference/derived firmware is not necessary because they do not make use of TE API Commands. Conversely, they directly make use of CyAPI.lib and CyUSB.dll, respectively. These two tools are therefore only able to update the firmware of the USB FX2 microcontroller, but not the FPGA configuration file (bitstream).
