Indirect configuration

I work with Cyclone V E and choose Indirect Configuration solution ( .jic ). AS 4X

Now I have : 90% (Failed), also there are no signals on my EPCQ32 pins.

Programming into RAM was successful (.sof)

May be I find a mistake in MSELs. I choose wrong conbination, because I thought that is just JTAG configuration.

00000 instead 10010

What can I do now? How can I find out real problem with experiment? Should signals be on EPCQ pins even with wrong MSELs?

    You may want to read table 7-3: configuration pin summary for cyclone v devices in the device handbook. It clarifies why the SFL can't drive any of the EPCS connected pins in FPP configuration mode.

    Apart from this problem, the EPCS stored configuration can't be read by the configuration controller in FPP mode.
