    Hi Jasmine,

    It will depend on your design an how critical the issue is. If you would like to have a faster reset and have the FPGA function then I would recommend to use the nReset pin.

    If you are using nConfig pin it will reconfigure the FPGA to golden image and you will need to wait for it to reconfigure to application image before your design start to function.
