Forum Post: pcie interface between dsp and fpga

Hi,

We are implementing PCIe interface between DSP(Root complex) and FPGA (End point.) in our custom board. From root complex how  can we know the  bus number to which the end point is connected.  How can we know the device id and vendor id from function 0 and how can we access and  program the configuration space of end point from root complex.  As DSP (6670) IS ROOT COMPLEX how can we access and program the configuration space of FPGA  (END POINT)

Thanks,

Nithin
