Stratix II Configuration Problem

Hi, We are having some issues configuring a stratix II FPGA. From quartus we can successfully program the flash from Quartus but the FPGA does not always configure correctly when power is applied....

Had similar problems with my Cyclone II board.

Disabling compressed bitstreams worked for me as well.

It was suggested by MSchmitt here on the forum that I replace the pull-down on nCE (R421 in your case) with a 0ohm resistor. Mine is currently 10K as well. From the looks of your design you need the nCE signal but I don't so perhaps in your case a smaller resistor could solve the issue?

I have not tried this yet, I just thought I'd let you know.
