Later on, using the same .bit file, I generated a .mcs file and then the .svf file; I loaded it on the PROM but, when I restart the board, the FPGA doesn't load the configuration file.
Are you using iMPACT software to program the XCF32P? What are the results of a VERIFY operation?
Have you checked power supplies on the board?

Hi Bob, thanks for your prompt response. Following your suggestion of checking power supplies we realised that we have missed to include the parameter CONFIG VCCAUX= "3.3" ; in the UCF file, thanks for that. Also, we were using iMPACT to generate the MCS and SVF files, and Adept to program the PROM because we have a Digilent JTAG cable, and that was the problem. Your question about the result of the VERIFY operation pushed us to look for ideas about how to use iMPACT with a Digilent JTAG cable and we found out this plugin from Digilent http://digilentinc.com/Products/Detail.cfm?NavPath=2,66,768&Prod=DIGILENT-PLUGIN , after plugin installation we were able to program the PROM and now it is working fine.
Thanks a lot for your help.
