Lots of warning while compiling - OpenCV with Vivado HLS

I am following the procedure given in the following link.

 

http://www.xilinx.com/support/documentation/application_notes/xapp1167.pdf

 

I downloaded the sample files too which this document refers to.

As given on page 13, I fired 'make sim'.

 

What I see is after doing this, I get a huge stream of warning messages.

 

The same warning messages keep reappearing.

 

I have attached the an image capture. Please let me know whats going on?

Hi vijayve,

It seems that it's ok to re-run 'make sim' the reference design (demo) on Windows.
Could you please post your design? it looks like there are empty streams being read.

Re: Lots of warning while compiling - OpenCV with Vivado HLS

Hi,

 

The variable names of images are incorrect in your top.cpp, which leads to read empty stream. Try replacing the corresponding code with this:

 

RGB_IMAGE img_0(rows, cols);
RGB_IMAGE img_1(rows, cols);
RGB_IMAGE img_2(rows, cols);


#pragma HLS dataflow

hls::AXIvideo2Mat(input, img_0);
hls::Erode(img_0, img_1);
hls::Mat2AXIvideo(img_2, output);
