Problems with configuring CycloneIV from EPCQ32A

After changing EPCS16 (soic 😎 to EPCQ32A on PCB Cyclone IV FPGA can't load configuration data at power ups (Active Serial x1 is used). Quartus project is recompiled, configuration device in Device a...

Hi,


Thank you for contacting Intel community.


When you said that after reprogramming EPCQ32A, FPGA couldn't get configure, do you mean it failed? Does it show any error message?


Have you also try this with the latest version of Quartus lite?


Regards,

Aiman

    Hi, Aiman.

    I don't quite follow what you meant by "error meassage". I can program EPCQ32A using USB Blaster without any error messages. I meant that FPGA couldn't get correct data from EPCQ32A. FPGA sends DCLK pulses and gets bytes from EPCQ32A after power up, but this process never stops. And FPGA isn't configured (no activity on it's pins). Also I've tried comparing .pof file which I used to program EPCQ32A and .pof-file I read back from EPCQ32A (using Examine option of Quartus programmer) and I see that files differs. It's also clear that EPCQ32A is still rewritable (at least it's not protected from writing bytes), because I can program different .pof files and read back different files which, however, differ from original files.

    I've tried using QuartusII 20.1 Light Edition, but it hasn't helped.

    I've tried to program, examine,erase and blank-check EPCS16 on another board using the same UBS Blaster and haven't had any problems.

    EPCQ32A IC is marked as follows :

    ALTERA

    EPCQ32A

    2115

    Does it look like it's a genuine Intel chip?
