Firmware update tools:

• DEWESoft Firmware Upgrade Tool:It requires DEWESoft device driver and DEWESoft API.It work only if the reference/derived architecture is running in the module.DEWESoft FUT is able to update the firmware of the USB FX2 microcontroller and the FPGA configuration file (fpga.bin bitstream).
• Open_FUT for generation 2:It requires DEWESoft device driver, Python and DEWESoft API.It works only if the reference/derived architecture is running in the module.Open_FUT is able to update the firmware of the USB FX2 microcontroller and the FPGA configuration file (bitstream fpga.bin).
• CyConsole = Cypress USB Console:It requires Cypress generic USB device driver and CyAPI.lib static library.It works also if the reference/derived architecture is not running in the module.It is used as recovery USB firmware tool (recovery boot)It requires to boot with EEPROM switched off (DEWESoft device is registered as Cypress device), then back on (EEPROM can be written).Some documentation in UM-USB-Firmware.pdf.Some examples here (firmware restore only).
• CyControl = Cypress USB Control Center (requires .NET Framework):It requires Cypress generic USB device driver, .Microsoft NET Framework (version ≥ 4.0.30319) and CyUSB.dll dynamic library.It works also if the reference/derived architecture is not running in the module.It is used as recovery USB firmware tool (recovery boot)It requires to boot with EEPROM switched off (DEWESoft device is registered as Cypress device), then back on (EEPROM can be written).Some examples here (firmware restore only).

Using Cypress firmware update tools with generation 2 modules does require a recovery boot, in order to force enumeration as Cypress generic USB device driver.
On the other side, using Cypress firmware update tools with generation 3 modules does not require a recovery boot. This is possible because the original Cypress generic USB device driver (in case of a recovery boot) and the Trenz Electronic USB FX2 device driver ( in case of a regular boot) are both Cypress driver. Trenz Electronic USB FX2 driver derives from the original Cypress generic USB device driver.
EEPROM switch shall always be on during EEPROM programming.
The firmware update procedure is similar for both generations. The following table summarizes the main differences.
