The TE USB FX2 The TE0300 micromodule can be configured by means of a firmware-upgrade (FWU) file (see next section “Micromodule Configuration” for further reference).
The first step in generating the FWU file is to generate the fpga.bin file corresponding to a given FPGA design.
...
To generate your own firmware upload file, please read the document “Generating_FWU_file.doc” in the “USBFWUTool” folder.
...
In order to generate the FWU file you shall
generate a bit-stream file from your Xilinx EDK design;
generate a PROM file from the bit-stream file;
generate a FWU file from the PROM file.
...
In order to generate a .bit
bit-stream file from your Xilinx EDK design, you shall
...
In order to generate a .bin
PROM file from the bit-stream file download.bit
, start Xilinx iMPACT. The following example shows the case of Xilinx iMPACT 11.3.
...
Select file / new project.
Choose create a new project.
Press OK.
...
Select prepare a PROM file.
Press OK.
Select step 1. storage target / Xilinx Flash/PROM of the left panel and press the left green arrow.
...
Select step 2. add storage device(s) / auto select PROM of the middle panel and press the right green arrow.
In step 3. enter data of the right panel
type fpga in the output file name
input field;
choose a suitable path for the output file location
input field;
select BIN (swap bits ON) from the drop-down menu file format
in the flash/PROM file property
sub-panel;
press the OK button in the bottom left corner of the current window.
...
Any other name than fpga for the output file name
input field is not allowed.
Just acknowledge the pup-up message.
...
Browse to the ./implementation/
folder of your ".
" project folder and select the bit-stream file download.bit
.
Press the open button in the bottom left corner of the current window.
...
Your design likely consist of just one device file.
So deny the request by pressing the NO button.
...
Just acknowledge the pup-up message.
Select operations / generate file... or double click generate file... from the iMPACT processes
panel.
You should see the following message in the main panel: generate succeeded.
...
You might now want to save your Xilinx iMPACT project settings for future use.
In the folder corresponding to the path you chose as the output file location
, you should find the fpga.bin
PROM file.
Once you have got your fpga.bin
PROM file, you can proceed and generate your FWU (= FirmWare Upgrade) file. The FWU file is a ZIP archive containing 3 files:

The step4_user\Bootload.ini
file defines some module start-up options. Version 1.0 of Bootload.ini has the following structure:
[Info]
– information section (do not edit this section)
Version
– Bootload.ini file format version
DeviceType
– 3 stands for current device type
[Settings]: settings section
FPGABitSwap
– see Xilinx UG332: Spartan-3 Generation Configuration User Guide, chapter SelectMAP Data Ordering (default = 1 = do bit swapping)
FPGAPowerON
– value of FX2_PS_EN after SPI Flash memory programming (see paragraph 6.8.2 Slide Switch S2) (default = 1 = power on after upgrade)
The step4_user\usb.bin
file contains the firmware to be written in the large EEPROM of the EZ-USB FX2LP USB microcontroller and loaded at module start-up to implement the DEWESoft instruction set.
