XCF32P configuration problem?

Hello:
 
       Now I am using two XCF32P PROM to  configure the XC5VLX220 FPGA in the selectMAP Master mode.The FPGA and XCF32P PROM can been configured through JTAG.
The  *.mcs file can been written into the XCF32P.But Power-on again,the XCF32P PROM can't configure the FPGA.In the selectMAP Master mode,the FPGA can give the XCF32P PROM 2Mhz cclk and the first  XCF32P CEO_n pin can convert from 1 to 0,to enable the second PROM. I found the D[7:0] port have no data output.I want somebody to tell me why
the XCF32P PROM can't configure the FPGA.
 
Thank you!
