Avalon-ST on Intel PCIe IP

Hi, I am using the Avalon-ST interface in my FPGA for streaming application. Most of the time, I will be sending data from host to FPGA. Memory write appears to be the right command for this task....

Your problem is probably on the host software side. How are you commanding the write? Are you sure that it is actually trying to move more than 64 bits in one operation? The IP is definitely capable of receiving an awful lot more than that but it's quite easy (speaking from experience) to have the software-side PCIe driver not actually do what you expected...
