**  Device:     SPI Serial Flash
**  Purpose:    The "designs" in this xapp445.zip are comprised of sets of
**              software utilities and associated files that demonstrate
**              SPI serial flash programming.  The command line software
**              utilities can program STMicroelectronics M25Pxx and M45PExx,
**              and Atmel AT45DBxx and AT25Fxx SPI Flash Memory devices.
**              Xapp445.zip includes two versions of the XSPI utility that are
**              packaged as install_xspi.zip and install_xspi_usb.zip.
**              The install_xspi.zip contains the utility version xspi.exe
**              for use with the Parallel Cable IV or Parallel Cable III. The
**              install_xspi_usb.zip contains the utility version xspi_usb.exe
**              for use with the Platform Cable USB, and Parallel Cable IV.
**              Both the install_xspi.zip and install_xspi_usb.zip files
**              contain the database file .xdv which is referenced by both
**              versions of the XSPI utility.

This readme describes the files that come with XAPP445.

*******************************************************************************

** IMPORTANT NOTES **

1) ISE iMPACT must be installed on the PC on which either version of the XPSI
   utility is launched. The USB version of XSPI uses the cable drivers from
   iMPACT.  iMPACT can be obtained via the ISE WebPACK software from
   http://www.xilinx.com.

2) Unzip the desired XSPI utility version into a user directory.  Type xspi or xspi_usb
   in a command window to display the list of commands available. If the xspi command
   is not found, make sure that xspi.exe or xspi_usb.exe and the database file (.xdv)
   are in the current working directory, or in a subdirectory specified in the PATH
   environment variable.

3) For the Platform Cable USB:
   If using iMPACT 9.1.03i (or later), for driver compatibility use
   xspi_usb.exe version 4.00 (or later).
   If using iMPACT 9.1.02i (or earlier), for driver compatibility use
   xspi_usb_for_ise_9_1_sp2_and_earlier.exe.

4) By default, xspi_usb.exe connects to the Platform USB Cable. For cable
   selection options (-select_cable N), refer to the XSPI commands by typing
   xspi_usb.

5) Added by Wojtek: the old x_spi utility was just fine. It was the "database" of parts
   which was not complete with newest 16 megabyte flash chips. If your x_spi program 
   is working now, then all you may need to do is to take the "database" from the new 
   x_spi release and use it with the old software utility.
