I am using VCU118 board to develop PCIe DMA following that video tutorial. The drivers worked fine on linux OS and Windows also, but the problem is that when I power off the FPGA and turn it on back I have to reload the bitstream again to make it work. the device is seen on lspci but the driver cannot detect the xdma) Despite that I set JTAG mode (M[2:0] = 101) to program QSPI Flash then I set QSPI mode (M[2:0] = 001) to load FPGA from Flash.
Does anyone know what is the reason for that behavior and how to overcome it?
Thanks in advance!

After doing power cycle of the FPGA, do you reboot the host machine?
