nCONFIG and nSTATUS,CONF_DONE always LOW EP4CE6

Hello everyone, i has problem about hardware of EP4CE6E22C8, i configure initialize pin like under

     About power supply, i sure that every bank has right voltage. The problem is when i connected through USB Blaster, quartus cannot detect device, when measure initialize pin, i see voltage in nSTATUS, nCONFIG, CONF_DONE always 0V although 3v3 pull up work. I checked chip solder right, 3v3 work, nSTATUS, nCONFIG, CONF_DONE do not touch GND. What should i do next ? Thanks everyone.

    Hi haduchieu,

     

    May I know what FPGA device you are using? Is it a devkit or custom board?

    Regards,
