Very High Speed IMX219 Camera w/ Xavier NX Jetpack 5

[eran.roll1]

Hi,

I would like to run a gstreamer pipeline which grabs frames from an IMX219 camera.

My requirements can vary from 1280x720@120FPS to 640x480@200FPS.

I am aware that this requires that I edit the kernel.
I have followed the documentation, and recompiled everything, but I am facing 3 main issues:

1. nvarguscamerasrc does not support 8bit pixel size
2. Once I go over 80FPS I can’t get a view of the entire image, it is always partial with a black stripe at the bottom, which appears to grow as I increate the FPS.
3. Even if I ignore the fact that the image is partial, FPS measurement of gstreamer does not get to 1280x720@120FPS, only to about 100. That is when running with 20W/6CORE and jetson_clocks --fan

My goal is to have that configuration without binning (0x174,0x175 = 0), and in 8 bit so I can increase the available bandwidth.

Any help will be much appreciated. My best guess is that it has something to do with the pix_clk or some other registers.

Thanks in advance.

Reference to below topic for 720p@120

120 fps mode support removed for imx219 sensor

Hi, We will keep only 720p60 mode in the default release. If you require 120fps mode, you may add the mode back to sensor driver and device tree. And rebuild/replace kernel. The sensor mode and device tree files: imx219_mode_tbls.h tegra194-camera-rbpcv2-imx219.dtsi

Hi @ShaneCCC ,

I am familiar with the post you are referring to. The problem I have is when I try to use this camera with crop only and without binning (Registers 0x174 = 0, 0x175 = 0), I can’t seem to get a picture which isn’t cut.
I see half the picture, and a wide black stripe on the other half.
This stripe gets smaller as I lower the frame rate.

Any idea what am I doing wrong?

I would suggest consulting with Sony for the sensor REG configuration.

Thanks
