Hello, I found out my problem.

I was not connecting nCS of EPCS properly.

Assigned it to "nCSO" in my top module, but passing "n_CSO" to the lower module.

I wonder why Quartus did not raise an error because "n_CSO" exists nowhere in my code...

It was bit tricky to find out, because configuration works totally fine.

I was not aware that the problem could be on my FPGA side.

Thanks,
