The (generation 2)TE USB FX2 driver should be already installed and a Generation 2 firmware should be already programmed in USB FX2 microcontroller's EEPROM and RAM.

Open_Fut (gen2) is a Trenz Electronic Python application that use Trenz Electronic Command API and DEWESoft C API to program USB firmware and FPGA bitstream.

It can be downloaded from here.

It is not possible to use for Firmware Recovery (USB EEPROM and USB RAM programming): use CyControl, CyConsole or OpenFutNet instead.

It can be used for:

Firmware Update (USB EEPROM programming): you should use a .iic file (EZ-USB FX2LP USB FX2 microcontroller firmware) ;
FPGA Configuration (SPI Flash and FPGA programming): both .bit and .mcs file formats for Xilinx Platform (not for third-party) SPI Flash memories are supported.

An update boot (aka TE USB FX2 firmware update) is a multi-step boot operation:

follow the same procedure desrcibed in update boot and use Open_Fut (gen 2) instead of DEWESoft.
TE USB FX2 module with the USB EEPROM enabled (when TE USB FX2 module is powered on) should be already inserted at this point.
A) TE USB FX2 module is seen under Device Driver as a Trenz Electronic Device. In this case, you should start a Recovery boot procedure to download Generation 2 firmware.
B) TE USB FX2 module is seen under Device Driver as a DEWESoft Device.
Open the USB Firmware Upgrade Tool Open_FUT (gen 2): double click ofut.py.
Press the "..." button (it means for "Select *.iic file or enter file path”) at left of "Program USB" button corresponding to the firmware file pathname selection
Select a suitable .iic firmware upload file. You can download the firmware availbale at Trenz Electronic GitHub.
Press the “Program USB: write IIC EEPROM” button if you want the *.iic file to be written into the large EEPROM of the EZ-USB FX2LP USB FX2 microcontroller.
When the progress bar reaches 100%, the following log text message notifies the successful completion of the USB upgrade procedure.

NOTE: the procedeure are the same of this link but with Dewesoft vid/pid (current_dw.iic) in place of Trenz Electronic vid/pid (currente_te.iic).

An FPGA Configuration (aka TE USB FX2 SPI and FPGA programming) is a multi-step operation:

Insert the TE USB FX2 module with the USB EEPROM enabled (when TE USB FX2 module is powered on).

A) TE USB FX2 module is seen under Device Driver as a Trenz Electronic Device. In this case, you should start a Recovery boot procedure.
B) TE USB FX2 module is seen under Device Driver as a DEWESoft Device.

Open a USB Firmware Upgrade Tool (double click ofut.py). Case B is considered true from now on: TE USB FX2 module is seen under Device Driver as a Trenz Electronic Device.
