Did you assign epcs controller outputs to device pins?

In Cyclone® III devices, the EPCS controller does not automatically assign its output pins to the dedicated configuration pins on the FPGA. Instead, the output pins are exported to the top level design, giving users the flexibility to connect to any EPCS devices.

Therefore, in order to use the EPCS Configuration Controller the pins must be assigned manually, and the following settings must be made the Quartus® II software.

Please follow these steps:

Choose Settings from the Assignments menu

Click Device and Pin Options from the Device category

Click Dual-Purpose Pins and then make the following changes:

Data[0] -> Use as regular I/O

Data[1] -> Use as regularr I/O

DCLK -> Use as regular I/O

FLASH_nCE/nCS0 -> Use as regular I/O[/b]
