Precondition

The (generation 2) TE03xx device 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:

EEPROM connection shall always be enabled during EEPROM programming.

A Firmware Update (aka Update Boot, more precisely TE USB FX2 firmware update) is a multi-step boot operation:

  • Check that EEPROM connection is enabled (EEPROM switch is set in a way to enable EPPROM connection to USB FX2 microcontroler)
  • 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. Case B is considered true from now on: TE USB FX2 module is seen under Device Driver as a DEWSoft 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.
The procedure is the same of Open_FUT (gen 3) but with Dewesoft vid/pid (current_dw.iic) in place of Trenz Electronic vid/pid (currente_te.iic).

FPGA Configuration

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

From now on it is possible to follow the same procedure of Open_FUT (gen 3).
