xilinix pci express core.. dma simulations

[sekhar_rjy]

Hi,

i am using xilinx pci express core for communication between processor and ipcore.
i am able to do write and read transactions from processor to ipcore. But when IPCORE inititates transaction to processor in DMA mode, Xilinx pci express core is receiving wr/rd request from IPCORE but is not transmitting that request to processor side.

can anybody help me in this regard... whether i need to do any configuration setting of xilinx pcie core for DMA transactions...

Thanks in advance,
Chandra Sekhar V

sir it is my final year project to implement single lane PCI express core and to design fpga board for this, I have idea of vhdl programming. I want to know from where should i start to understand PCI express protocol and to run its core successfully in fpga board and perform communinication between Host pc and FPGA. Please provide relevant materials and references.
