Serial configuration problem of Cyclone II device using quatrus 9.1

I have a working design implemented in a Cyclone EP2C5T144C7 device conficgured by an EPCS1 prom in Active Serial mode.

I switched to Quartus 9.1, recompiled the project, and reprogrammed the EPCS1 with the new pof file, all without errors. Now the FPGA configuration never completes. In other words, it never finishes reading the prom after the power is cycled - it just keeps sending clocks.

I am assuming that there is some option that I have to explicitly set someplace to make the pof file behave as before, but I cant figure out what it is.

Many thanks in advance for any advice!!

    Hi,

    this option "Active Serial Mode CONF_DONE pin error checking is disabled" is exactly what you actively set when generating "manually" the pof as I described. Thus it seems this option was deactivated in v9.0 and has been (whatever reason) activated in v9.1 now...

    BTW.: I asked ALTERA if this deactivation might cause false or incomplete configurations due to noise, ... during configuration not to be detected, but this is not.

    Did Altera support tell anything about non-functional "generate compressed bitstreams" option with AS configuration, that has been reported in the forum? If so, did they tell, when a fix will be available?

    Hi,

    I got the information (as part of my service request)

    "For this current issue, the internal software team has been notified and they would work on it for the next version."

    Thus it might be fixed in SP1 or at least in v10...

    I know this is an old thread, but I found a solution for this. I was getting bad RBF files using bitstream compression for my Stratix II part when I had told the main Quartus software to generate the RBF files in the settings checkbox. If I instead generated the RBF file using the commandline tool, the problem went away. Here's how to do it.

    Make a file, call it "options.txt", put this one line in it

    BITSTREAM_COMPRESSION=ON

    Now run this commandline

    quartus_cpf -c --option=options.txt Project.sof Project.rbf

    This worked great. I've not tried making a POF file in this manner, but quartus_cpf allows you to do that, too. Just type "quartus_cpf -h" to get help on how to do it.
