hello sir ,

               i am interfacing fx3 board with ov7670 camera module , but i am unable to stream data on vlc as i am having doubt of connecting XCLK pin of ov7670 on fx3 . also PCLK pin should have 24 MHZ clock frequency for 30 fps irrespective of video format . I am using VGA (640x480) resolution , i have made changes in vs frame descriptor and video format . please help what else i have to change ,i have used AN75779 as a reference.

Since we don't have the datasheet of OV7670. Could you please explain the function of pin XCLK? Are you not sure how to connect it?

Actually sir in OV7670 camera module this pin  is input system clock , but in fx3 no pin is shown which could act as clock for ov7670 .so, please tell which pin on fx3 can be used to provide system clock to camera module.

Hi manisha,

I suggest you provide clock to img sensor with crystal or external clock.
