[No card is found!] after build the host

[douzidouer]

Hi there

at the very beginning, by using the command <sudo /opt/xilinx/xrt/bin/xbmgmt flash --scan> I can got the card info, as following. Card [0000:01:00.0] Card type: u55n Flash type: SPI Flashable partition running on FPGA: xilinx_u55n_recovery,[ID=0x5],[SC=INACTIVE] Flashable partitions installed in system: xilinx_u55n_gen3x4_xdma_base_1,[ID=0x9964c19cdb53eb6c],[SC=7.1.12]

but after I build the host and try to mining, the card gone and when I scan, it shows [No card is found!]. any hints or idea how to make the card available? thanks
