We use Cyclone V(5CGXFC5C6F27C7) as native PCIE endpoint. 

 

when we use avalon-mm interface and write data to system memory(Linux x86 platform), but system memory has no data(all zeros). Avalon-MM interface is 64-bits width, burstcount is 8. 

 

is there anyone that can help us? 

 

Thanks in advance
