Csi sensor has 3000fps, but only get 600fps with v4l2

Hi NV_Team,

We have csi raw sensor imx459 with 1314x12@3000fps, but only get 600fps with v4l2.
If we change to 1000fps, the v4l2 can get 1000fps successfully.

Please help to check is the limitation orin nano hardware or vi driver or the orthers ? Thanks.

The issue you’re experiencing could be due to a combination of factors related to the sensor, the v4l2 driver, and the Jetson Orin Nano hardware.

  1. Sensor (IMX459): The IMX459 sensor from Sony is a Stacked SPAD Depth Sensor designed for automotive LiDAR applications. It can be controlled via a MIPI CSI-2 serial output 4/2 lane interface. However, the specific frame rate limitations of this sensor are not mentioned in the available resources.

  2. v4l2 Driver: The v4l2 driver can indeed influence the frame rate. For instance, some users have reported that they were able to limit the frames per second by setting it on the v4l2loopback device. However, it’s also been noted that without specifying a frame rate, the capture can be buggy, possibly due to trying to capture too much data.

  3. Jetson Orin Nano Hardware: The Jetson Orin Nano has specific hardware limitations. For instance, each data lane has a peak bandwidth of up to 1.5 Gbps⁴. If the data rate with your desired frame rate exceeds the max CSI bandwidth per 4 lanes (i.e., 1.5 Gbps * 4 = 6 Gbps), this could be a limiting factor.

Hi AminAlaghband,

Thanks for your information, we use 4lane csi with orin nano.
And we have tried gst command with videotestsrc, orin nano works up to 6000fps is fine.

Hi ShaneCCC,

After boost clock, now v4l2 can up 1500fps(without boost clock only get about 600fps ), sensor output 1314x12@3000fps, but csi trace still get CHANSEL_NOMATCH logs.

Does the VI limit the frame rate ? Can we set larger boost clock values to increase fps ? Thanks.

Hi ShaneCCC,

Can you give some more advices about this ?

Does CHANSEL_NOMATCH shows in this case?

Yes.

1000fps and 100fps both have CHANEL_NOMATCH = 0x589, same as 3000fps or 6000fps.

What the max ISP/CSI/VIC clocks and the max frame rate supported by Orin Nano?

This docs only show the AGX Orin features.

https://docs.nvidia.com/vpi/algo_performance.html#maxout_clocks

CSI/VI bandwidth should not the problem. I would suspect the bottleneck could be the memory speed.

Hi ShaneCCC,

We change the sensor to AGX Orin Devkit (32GB), and boost clock.

The frame rate is same as Orin Nano, is there any other reasons ?

Can we use Argus-camera to test this sensor ? (we use argus can’t open to display it now)

I think get 1500 is more better result. As I mention in previous comment the bottleneck would be the relative to memory performance.

Suppose Argus would get more worse due to involve more elements.

Thanks
