 +**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). ​ 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). ​
