 ======  Indirect Programming of SPI Flash ======
-[[http://www.ztex.de/usb-fpga-2/|ZTEX Series 2 FPGA Board]] have SPI Flash memory that can be used to store the Bitstream. Most comfortable way to write data to Flash is to use the SDK ([[en:software:deviceserver]], [[en:software:fwloader]] or the API). Nevertheless the SPI Flash can also be programmed indirectly through JTAG and FPGA using the Xilinx Impact tool.

Most comfortable way to write data to Flash is to use the SDK ([[en:software:deviceserver]], [[en:software:fwloader]] or the API). Nevertheless, on EZ-USB FX2 based FPGA Boards the SPI Flash can also be programmed indirectly through JTAG and FPGA using the Xilinx Impact tool.
+**The method described here does not work with EZ-USB FX3 based boards because they completely handle the FPGA configuration process per Firmware. **
 The brand of SPI Flash which is used on ZTEX FPGA Boards may vary (mostly Spansion S25FL127S or S25FL216K) but all types support a set of basic commands which make them compatible (and usable with the same EZ-USB Firmware).
