Connect Tech Inc. | FreeForm/Express S6 - PCIe Spartan-6 FMC Carrier | User Manual
Revision 0.01 12
Configuration The FreeForm/Express S6 is designed so that the Spartan-6 configuration image is automatically loaded
from the on-board SPI flash at power- up. When a valid configuration is loaded, led D4 is illuminated.
JTAG configuration can be used at any time to program the FPGA.
The FreeForm/Express S6 is fitted with a x4 32 Mbit SPI flash (Winbond W25Q32BVSFIG), which can be
programmed indirectly via JTAG using Xilinx’s IMPACT.
