    Problem with connecting videosensor.

      I write a firmware for a system based on FX3 and videosensor. I programmed GPIF as described in AN75779 and created DMA chanel for translate data to the PC. I didn't make changes in data, only translate.


      As described in AN75779, I define the size of DMA bufer as 16kB, and the bufer count as 4. But when I try to translate data it translate only few frames, and then translation terminated and device didn't detect by Cypress CC.


      I reduced the size of DMA bufer to 1kB.  Now traslate didn't terminat, but the data arrived discordantly, so i can't capture properly image.


      Where there is may be a problem and how solve it?
