I'm going to use AN75779 Version *B on our environment for following system, 

  Sensor Size: SXGA(1024 x 1280)
  Sensor frame rate: 60 fps

  [GPIF II Setting] 

How do I have to customize AN75779 source code ? 

When I use AN75779 with no customize, following error has been displayed. 
  CyU3PDmaMultiChannelCommitBuffer() ---> Err71 

If enabling flag BACKFLOW_DETECT, 
"Backflow detected" message was displayed on terminal output, and "cbArg" are 0x1005 and 0x1006 by turns. 

I think that I could customize GPIF II setting for 16bit mode. 
We'd like to know how to customize for Sensor size and frame rate settings.

 The sensor settings depend on the type of sensor you are using. Please specify it , or try the sensor documentation to get the settings.

I easily list changes from AN75779.
1. 16bit does image bus width with GPIF-II designer.
2. I make a counter for an interrupt half with GPIF-II designer.
3. I change image size in cyfxuvcdscr.c.
4. I change image size in uvc.c.
Please try it.
Thank you very much for your help.
