How to solve nSTATUS can't go high

I have made a FPGA board using Cyclone V SOC 5CSXFC6D6F; The HPS is running, the Quartus Programmer can detect the HPS(SOC part), but the FPGA part can't be detect via JTAG; and I've found the nSTATUS can't go high after power up, but generate a pulse about 4.3kHz.

    Are all the power supplies to the FPGA up and correct? Are all the power pins receiving the right voltage? Are you pulling nSTATUS up with a suitable pullup resistor to an appropriate rail?

    the Quartus Programmer can detect the HPS

    Via JTAG?

    For the JTAG chain to be partially working but not find the FPGA I'd suspect one of the above.
