14.2 / 2012.2 Video IP - Why does the Video IP stop working (producing TLAST output) when the optional AXI4-Lite interface is not selected in EDK?

Description

Why does the Video IP stop working (producing TLAST output) when the optional AXI4-Lite interface is not selected in EDK?

 This affects the following EDK 14.2 IP: 

  • LogiCORE IP Chroma Resampler v3.00.a
  • LogiCORE IP Color Correction Matrix v5.00.a
  • LogiCORE IP Color Filter Array Interpolation v6.00.a
  • LogiCORE IP Defective Pixel Correction v6.00.a
  • LogiCORE IP Gamma Correction v6.00.a
  • LogiCORE IP Image Edge Enhancement v5.00.a
  • LogiCORE IP Image Noise Reduction v5.00.a
  • LogiCORE IP Image Statistics v5.00.a
  • LogiCORE IP RGB to YCrCb Color-Space Converter v6.00.a
  • LogiCORE IP YCrCb to RGB Color-Space Converter v6.00.a 

解决方案

This is a known issue caused by the s_axi_aresetn pin defaulting to 0 when not used.
 
This has been fixed in the EDK 14.3 IP:
 
  • LogiCORE IP Chroma Resampler v3.01.a
  • LogiCORE IP Color Correction Matrix v5.01.a
  • LogiCORE IP Color Filter Array Interpolation v6.01.a
  • LogiCORE IP Defective Pixel Correction v6.01.a
  • LogiCORE IP Gamma Correction v6.01.a
  • LogiCORE IP Image Edge Enhancement v5.01.a
  • LogiCORE IP Image Noise Reduction v5.01.a
  • LogiCORE IP Image Statistics v5.01.a
  • LogiCORE IP RGB to YCrCb Color-Space Converter v6.01.a
  • LogiCORE IP YCrCb to RGB Color-Space Converter v6.01.a


In EDK 14.2 you can work around this by adding the following line to the MHS instantiation of any of these cores.

PORT s_axi_aresetn = net_vcc
