As per the "Virtex-6 FPGA Configuration User Guide" (https://www.xilinx.com/support/documentation/user_guides/ug360.pdf ), "The SPI device must support I/Os of 2.5V or lower; otherwise level shifters are required because Virtex-6 devices do not directly support 3.3V I/O."
FL-L is a 3.3V device, so you may not be able to use it directly with Virtex-6. I suggest you to contact Xilinx for more information.
Thanks and Regards,
Thanks a lot.
