mmilos (Member) asked a question. October 1, 2020 at 1:18 PM. QDMA v4.0 stream card to host transfers not working. Upon upgrading project from QDMA version 3.0 to version 4.0 i noticed that c2h transfers are no longer working. After further inspection i noticed that s_axis_c2h_cmpt_tready pin is always low which prevents me from sending any data.
