The PCIE device cannot be identified. Procedure

I’m going to ignore this problem and I’ll compile my source code into a *. Ko file and then apply “insmod” to load the driver.The driver can be loaded properly, but the sample program cannot be run because of the state of the PCIE interface.
I use “dmesg” to see the information that comes with installing the driver. I’ve read “cant’ enable device: Bar 0 [mem 0x00000000-0x000fffff] not claimed”. This is a deadly problem.
The PCIE card chip is SmartFusion2 SoC FPGA PCIe.
