hi, i have developed a spartan ii pci board. fpga is configured via eprom, since i havent got any results, as the first step to find the problem (which could be the pci firmware or the driver i wrote, signal integrity,etc!), i decided to read the fpga status register after configuration and it's all zeros, which means fpga configuration has been unsuccesful, but on the other hand the DONE pin goes high after power up, which indicates that the fpga has been configured ok, so what is it? is the fpga configured or not?
 

IF the Done pin goes high it means the FPGA was downloaded correctly, but do you see it being off after startup and then go high?

One problem can be the configuration mode of your FPGA, if the board has different ways of configuring the FPGA, then maybe you should look at the M1,M2 and M3 pins to make sure your FPGA is using the correct mode of programming.
