Cyclone 2 - how to force reconfigure from inside FPGA?

I have a Cyclone 2 configured via AS from EPCS4 chip.

How do I force reconfiguration from within FPGA after EPCS4 content update?

I do not have the access to the external nCONFIG pin from the inside logic.

    try running the megawizard and seeing if you have a remote update core. I don't know if CII has it. CIII does. Search for "remote update" on this blog. There are lots of people asking questions on this subject. Good luck, you will need it.:wacko:

    Cyclone II doesn't have the required remote update hardware. As far as I know, there's no means to force a reconfiguration other than asserting NCONFIG pin or through a JTAG instruction.
