Could not find /dev/xdma0_user

[Ayden-hnliu]

Hi! I encountered an issue when I finished installing the xdma driver to connect my Xilinx vc707 evaluation board with my host computer through PCIe. I want to use dnnweaver2 to run yolo on my fpga board, and the dnnweaver needs a device which is /dev/xdma0_user to interact with the hardware. However, when I loaded the xdma driver, there isn't xdma0_user in the /dev.
When I run the bash in linux terminal:

'$lspci | grep Xilinx'

the output is as follows:
'03:00.0 Serial controller: Xilinx Corporation Device 7021'
which indicates that my vc707 board has been physically connected to the host through PCIe.
However when I finished installing the xdma driver and run the following bash:
'$ cd /dev'
'$ ls | grep xdma'
the outputs are as follows:
'xdma xdma0_c2h_0 xdma0_control xdma0_events_0 xdma0_events_1 xdma0_events_10 xdma0_events_11 xdma0_events_12 xdma0_events_13 xdma0_events_14 xdma0_events_15 xdma0_events_2 xdma0_events_3 xdma0_events_4 xdma0_events_5 xdma0_events_6 xdma0_events_7 xdma0_events_8 xdma0_events_9 xdma0_h2c_0'
which indicates that there doesn't exist xdma0_user so that dnn_weaver could not interact with my fpga board correctly.
Do you guys know what is going wrong with this situation? Thank you in advance!
