Segmentation fault

[qiuhaojie]

After I finished compiling the hw section and burning the bit flow through the jtag interface into vcu118, I executed insmod coyote_drv.ko A segment error has occurred, as shown below And the printed kernel information is as follows: The read configuration information is all 1. I do not know the cause

Did your rescan the PCIe bus?

[qiuhaojie]

Yes, restart the host after burning the bitstream. After restart, check the device before loading the driver and input instructions lspci -vv -d 10EE: However, insmod coyote_drv.ko will still appear Segmentation fault.

All the information is as follows:

What is the benchmark you are running and what is the config?

[qiuhaojie]

The instructions I entered were:

cmake -DFDEV_NAME=vcu118 -DEXAMPLE=gbm_dtrees ..

make shell compile

Then load the bitstream to vcu118, restart the host, and load the driver to produce this error
