When I add a Winbond SPI Flash for Indirect programming, I am prompted for a Data Width. Does Virtex-6 FPGA support x2 or x4 SPI? The documentation does not include details on x2 or x34 SPI for Virtex-6 FPGA.
This is an issue with the iMPACT GUI. Virtex-6 FPGA does not support x2 or x4 SPI programming. Select Serial Data and continue as normal with programming. This issue is planned to be resolved in iMPACT 12.2.
