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...

In that case 1.1V is really strange.... what pull-up to you have on nStatus, and to which power supply is it connected to?
