Hi,


Feedback from our internal team;


It seems like the configuration issue is due to .pof content programmed in EPCQ32A is corrupted since the read back .pof is differed compared to the .pof used to program the EPCQ32A.


Does the issue happens on all the boards? How did you program the .pof into EPCQ32A? Did you regenerate the .pof with EPCQ32A configuration device? Do you able to try program ECPQ32A via JIC programming?


Regards,

Aiman

    Hi!

    I'm using only one board for this experiments, but the situation is the same for 2 tested EPCQ32A. I'm programming .pof file into EPCQ32A using Quartus Programmer tool and USB-Blaster. Can't program JIC since there's no JTAG interface on the board.

    Yes, I changed EPCS16 to EPCQ32A in Quartus->Assignments->Device and Pin Options->Configuration and recompile the project to generate new .pof file. Now I'm wating for ordered EPCQ32 to try to work with it. Maybe this will help to clarify the situation.
