The TE USB FX2 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.
FWU file generation
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.
bit-stream file from your Xilinx EDK design (link)
fpga.bin file from the PROM file (link)
FWU file from the 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:
Bootload.ini– TE0320 booting settings (see paragraph 10.2.4.3.1 Bootload.ini file)fpga.bin– FPGA configuration PROM file
usb.bin– EZ-USB FX2LP USB microcontroller firmware
To create your FWU file, you shall
replace the existing
step4_user\fpga.binwith the latestfpga.bin(once per design)zip the 3 files
rename the
zipfile extension tofwuupload the file as explained in paragraph 10.2.5 Firmware Upgrade Tool utilization.

10.2.4.3.1Bootload.ini file
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 versionDeviceType– 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)
10.2.4.3.2usb.bin file
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.

Once you have got your fpga.in file, you can proceed and generate your FWU file. The FWU file is a ZIP file containing 3 files:
