XDMA Streaming C2H (Windows)

Using XDMA under Windows we are able to transfer OK  data chunks up to 1MB  using ReadFille on C2H.
But we can't transfer larger chunks. We don't understadn why we are not able to transcend this limit.

Can anybody help us with this problem? 

Thanks a bunch!

Re: XDMA Streaming C2H (Windows)

Could you explain a little more? What is the transfer size? What would be the result of doing that?

Re: XDMA Streaming C2H (Windows)

Transfer size: refers to the amount of data,
Result: For example, if you need to transfer more than 1MB of data, the C2H channel will not work. I don't know what is going on. It feels like a driver problem.
Can you fix this?
