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:
- 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.
Firmware Update
EEPROM connection shall always be enabled during EEPROM programming.
A Firmware Update (aka update boot , TE USB FX2 firmware update) is a multi-step boot operation:
NOTE: the procedure is the same of Open_FUT (gen 3). link 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:
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 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. Case B is considered true from now on: TE USB FX2 module is seen under Device Driver as a Trenz Electronic Device.
From now on it is possible to follow the same procedure of Open_FUT (gen 3).
