    AN75779 CyU3PDmaMultiChannelSetWrapUp() Problem

    hyeukchang.kwon

       I used AN75779(How to Implement an Image Sensor Interface with EZ-USB® FX3™ in a USB) Source.

         

      CyU3PDmaMultiChannelSetWrapUp() function is succeed. But Sometimes CyFxUvcApplnDmaCallback() isn't called.

         

      So losing about 2 frame per second, 28 frame appears.

         

      Please help me.

         

      Thanks.
