Hardware Trigger for Image Capture

Hi All,

 

In the example codes provided for image capture from OV5640 using imx6, i always see that the image capture is using v4l2 either being read from a older buffer or started with a software trigger. Is it possible to start a image capture using external hardware trigger? is there any driver or v4l2 limitation? is there a feature in ov5640 that can be used to achieve this?

 

I want the frame at a particular instant where the hardware trigger is happening. So it is not possible to start a capture from software in my application.

 

Thanks in advance!!
