PCIe to FIFO loopback

Hi I have replaced the onchip memory with onchip fifo and have made connections as below (using QSYS).

fifo clk_in to pcie_hard_ip_0.pcie_core_clk

fifo reset_in to clk_0.clk_reset

fifo.in to dma_write_master_0.Data_Write_Master

ffifo in_csr to pcie_hard_ip_0.bar1_0

fifo.out to dma_read_master_0.Data_Read_Master

I have assigned 0X07000000 to fifo_in

0X07000004 to fifo_out and

0X070000020 to in_csr.

do i have to modify any logic in Modular_DMA modules
