hi, when i use a10_pcie_ avmm_ dma for acessing a ddr4 of 4GB,how can i set the parameters to traverse all addresses of ddr4?

Hi Sir,

The DMA interface PCIe AMM setting used 64bits addressing. And for 4GB of DDR4 memory, it only need 32bits (2^32) addressing. Thus, it is more than enough to traverse all addresses of DDR4.
