Thanks.

Yes, It has nothing to do with the external crystal as DCLK is supplied by internal 10M clock.

The problem is exactly the same as described in the thread http://www.alteraforum.com/forum/showthread.php?t=26422 (http://www.alteraforum.com/forum/showthread.php?t=26422)

Configuration is correct when I touch a scope probe on the DCLK.

I have tried to connect a 1K resister or a 47nF capacitor between DCLK and GND, but it didn't contribute.

I will look for other means to solve the problem instead of replacing the EPCS16 with EPCS4.

I have tried to Disable AS mode CONF_DONE error check, but it doesn't matter.
