 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.
