Can I get EP bar Information??

Hello

I have C6670 EVM board.

My project has PCIe Communication C6670 to FPGA.

C6670 is RC mode and FPGA is EP mode.

when FPGA board  connected Linux x86 system. working is fine.  But Connected C6670,  BAR[0] is all zero.

How can I know BAR size and BAR  PCIe Address?? (like pci_resource_len, pci_resource_start in linux function)
