EP3C25 nStatus 1V

I have five EP3C25 borad, 3 of them are working well. But the rest 2 will sometimes boot fail. The working mode is AS or fast AS from EPCS4. There're 10K pull up on nStatus, nConfig, Conf_done, MSELs...

I connect the nStatus via a 10K resistor to 3V power. This 3V is not the same net as VCCIO or VCCA which is connected to EP3C25, but the voltage is the same. Will this cause the problem?
