Use IMX296C on Jetson Nano

I’m using the ROI function of imx296c, but I don’t see how to use it in the driver. How to use ROI
in Jetson Nano b01? any help?

What’s kind of the ROI function you want to?

Have a check below, it’s current release API.

I want to narrow the camera area and increase the image acquisition rate. But I don`t know how to do it.

Have a reference to below doc if using gstreamer.

It`s helpful for me. Thanks a lot.
