The Configuration Problem Solver

---

CONCLUSION

Configuration is not being performed on the device.

The CS1 is the Chip Select that enables the FPGA for configuration in the Express Mode. If the CS1 is Low the FPGA will ignore all CCLK transitions and will not configure. If this is the lead device in a daisy-chain, or a single device, attach a pullup resistor to CS1 or make adjustments to whatever logical device is driving this input to bring it to a Logic High. If this is a secondary device in a daisy-Chain then begin trouble shooting why the preceeding device did not bring it's DOUT high which should be driving the CS1.
