This blog highlights the RidgeRun support for Jetson Xavier and Jetson Tegra platform on developing a CMOS Image Sensor Linux Driver for Sony IMX219.
Driver Features:
L4T 31.1 and Jetpack 4.1V4l2 Media controller driverOne camera capturing (TODO: to expand to 6 cameras)Tested resolution 3280 x 2464 @ 15 fpsTested resolution 720p @ 78 fpsTested resolution 1640x1232 @ 30 fpsTested resolution 820x616 @ 30 fpsTested with J20 Auvidea board.Capture with v4l2src and also with nvarguscamerasrc using the ISP.Images attached here are taken during the developing driver for Sony IMX219 image sensor, testing various image capture and display options, performance and latency measurement in our R&D lab located in CostaRica. Various tests are carried out using GStreamer pipelines.
Enabling and building the driver with Auvidea J20 Expansion board, Example GStreamer pipelines, Performance, Latency measurement details are shared in the RidgeRun developer wiki's mentioned at the end of this blog.

Frames showing how the glass to glass latency measurement method is setup by our team while testing for image capture using IMX219 camera mode at 3280x2464@16fps resolution for Xavier platform.
Glass to glass latency measured is 215 ms (07:772 minus 07:557).Time readings can be seen in the displays.
