Will ISP IP Be Required For CSI-2 Cameras For Jetson?

Hello,

Will ISP IP be required to get CSI-2 based cameras to work via the expansion port?
After taking a quick look at the available source, seems a lot of the hooks are ready
minus a published driver for the CSI-2 interface on the Tegra.

Maybe I missed something - just wanted to ask though.

Thanks,
John Westmoreland

The CSI-2 ports are accessible through gstreamer API (as gstomx element). If you run gst-inspect, you will see the camera ports listed. Here’s some brief info about gstreamer http://elinux.org/Jetson/H264_Codec

Hello Dustin,

Thanks for your reply. I will take a look at the gstreamer stuff.

I take it that it lists the ports because they exist on the Tegra, or do you actually have some cameras
connected to the CSI-2 port via the expansion connector on Jetson? Just wondering.

Best Regards,

All of the available elements are listed, not only those that are currently in use.

nv_omx_camera2 is likely the element to use, it has a lot of camera properties available. One thing I noticed in R19.3, only gstreamer-0.10 has the nv_omx plugins implemented (not gstreamer-1.0 yet).

I haven’t found a MIPI CSI-2 1x4 or 1x1 compatible with the Jetson yet, let us know if you do.

Thanks for the reply Dustin.

I will let you know if I find something.
