I need your help with programming problem in EPF10K100AR1-3.

In the board is implemented daisy chain for three devices, 2 EPF10K100ARI and EPM7256, when programming through JTAG with usb blaster all is OK, but in operation, the microprocessor in board load the EPF10K100ARI in parallel synch, but this fail and generate error in configuration, the logic level in pin NSTATUS show this.

This design is older, but is completely functional.

I not undestand why now this not operate?.
