Why do I see DMA data error when running the DMA driver for AN690 ArriaV PCIe Gen2 x4 AVMM DMA reference design? - Why do I see DMA data error when running the DMA driver for AN690 ArriaV PCIe Gen2 x4 AVMM DMA reference design? Description You may see this error when the software uses memory region greater than 32bit addressing. Resolution Open the “top.qsys” file in Qsys, change the “Address width of accessible PCIe memory space” setting from 32 to 64 for “pcie_256_hip_avmm_0” design component (PCIe HIP), regenerate the Qsys system and recompile the design.
