AXI-Lite control signals are not generated for a stream-in, stream-out function #119

Vivado synthesis fails for this function which has streams as inputs and a stream as the output. Is there a quick fix for that?

I missed out a conflicting HLS pragma. With that being removed control signals are generated OK.
