i have design board with the cyclone V part - 5CGXFC3B6U15A7N - and i wish to program is with STM - MCU that connected in FPP mode with flash. i have done the program in the MCU and check the Data line and its seems to be O.K. but the CONF_DONE I/O is not getting up, the speed of the data transfer from the flash to the FPGA is very low as 100khz, that data line have a pull-up resistors and the DCLK signal have a pull-down resistor, can you advice what is the problem ?
You mentioned that pull down on DCLK and Data. As per user guide at link below, seems like it cannot be. You will need to follow the connection as shown at user guide below:
