JTAG Chain problem - no device detected (Tried with multiple boards)

Hi everyone, I'm doing some work with custom cyclone III boards and am in the process of trying to program the device using a JTAG port and a USB Blaster cable. The boards were used last yea...

I have also the JTAG issue on EP325F324(Cyclone3) Device.

nCE = Pull down to GND with Zero Ohm

nStatus = pull_up(3.3v) with 10k

Conf_Done = Pull_Up(3.3v) with 10k

nConfig = Pull_up (3.3v) with 10k

Mode-set = "0000"

Jtag chain Debugger is sying as "Error: Incorrct TCK Value"

What I am missing for JTAG Configuration for this cyclone3 device?
