Can't recognize silicon ID for device 1

I designed FPGA Board using Cyclone V Device and EPCQ512 programming.

When program the device using .sof it loads successful and output is also correct.

But when i try to program using .jic it failed to load the program.

Afterthat, i have replaced EPCQ device with Micron.

In micron device, .jic file loads successful, but the output is wrong (cannot see the actual output).

I have also verified the configuration selection. That is also correct.

Please give me the solution for this device.

    I can't read the text on the images you've posted. However, it looks like it's reporting that it can't recognise one of the devices. Is this the same issue as when it 'works' with the Micron part?

    the output is wrong

    By this, do you meant the FPGA is not doing what you expect having booted from the EPCQ?

    Cheers,

    1).jic file is not loading in EPCQ512.

    2) Loaded in Micron device, but not shows correct output.

    Need solution for this older issue.

    Having loaded the Micron device and power cycled the board, does the FPGA's 'CONF_DONE' pin go high?

    Missed to tell which Micron flash has been used.

    If flash verifies O.K. but configuration isn't accepted by FPGA, either wrong settings in Programming File Conversion Tool or MSEL bits must be expected. Checking for error during configuration load (nSTATUS and CONFIG_DONE signaling, how many bits are read from the flash) is interesting nevertheless.

    There's nothing wrong with the bit of schematic you've posted. Does CONF_DONE go high?

    Cheers,

    If CONF_DONE is going high the FPGA has successfully booted from the serial FLASH device. If the FPGA isn't then doing what you expect then the issue is with your design. You need to start debugging.

    If the behaviour is different as compared to when you program it with the .sof then check that you've used the correct .sof when generating your .jic file.

    If you have used the right one then detail the behaviour differences for us to consider.

    Cheers,
