The problem of epcs controller in quartus ii 11。0

Hi，friends！

I'v got a boring problem recently.I was alway using quartus ii 9.0 before.Now in the quartus ii 11.0, it makes some changes,which confuses me.Take the epcs controller for example.In the SOPC builder ,if it contains epcs controller, there will be four epcs special pins on the top floor,which is different from the versons before.

Here is the problem.How shall I deal with the four fins? Treat it as the normal pins or something else? And what can I do in the setting property? Thinks for your help.

    Hi,

    Just faced the same issue myself. You should change the Dual-Purpose pins related to EPCS connection to Regular I/O and make the connection yourself.

    This is documented in the "Embedded Peripherals IP User Guide" (under "Chapter 5: EPCS Serial Flash Controller Core").

    Just did it myself and it works ...
