problem in my own designed board

Hi
I have made a pcb board of the attached schematic, but I it has a problem. When I
program the FPGA (xc3s400) solely through jtag (Platform cable usb II) the FPGA is program and okay, also when I
program the FLASH (xcf04s) solely it is programmed as well (as impact says), but the problem is this that after programming the FLAHS,
the FPGA is not configured and programmed by FLASH through master serial mode! as I check the DONE pin of FPGA, it never comes high ( it is low, indicating that FPGA has not
been configured by FLASH), also the CCLK pin of FPGA continues to pulsing the CLK pin of FLASH for ever!
I checked every thing but I couldnt find out what is the problem . I would be very thankfull if somebody can help me solving this problem
thanks in advance
Regards

1.  In the future, please do not post duplicate threads in multiple forums concerning identical questions or problems.  This is called 'cross-posting' and is considered bad manners in these forums.

 

2.  The duplicate thread you started in the Spartan forum has generated several responses.  Please continue the discussion in that other thread.
