描述

My Image Processing Pipeline core does not generate when I select a constant interface with the Maximum Number of Rows and Columns set to 1024. 

The following error occurs:

ERROR:sim - Error: XST failed for v_ipipe_v1_0. ERROR:Xst:2587 - Port <active_bottom> of instance <cfa> has different type in definition <var_min_cfa_wrapper>."

Why is this happening?

解决方案

This is a known issue with the Image Processing Pipeline. 

To work around the problem, increase the number of lines to 1025 or another value that might include the entire video frame. 

This larger number only results in a small increase in size.
