CSI camera can find, but can not open

Xavier nx jetpack version is 5.0.2[L4T 35.1.0].

I have two imx219 cameras.
And can find them.

v4l2-ctl --list-device

NVIDIA Tegra Video Input Device (platform:tegra-camrtc-ca):
vi-output, imx219 9-0010 (platform:tegra-capture-vi:0):
vi-output, imx219 10-0010 (platform:tegra-capture-vi:2):

but do nvgstcapture-1.0 show message

** Message: 10:32:03.371:<main:4651> iterating capture loop .....
Error generated. /dvs/git/dirty/git-master_linux/multimedia/nvgstreamer/gst-nvarguscamera/gstnvarguscamerasrc.cpp, execute:751 No cameras available
NvMMLiteOpen : Block : BlockType = 4
===== NVMEDIA: NVENC =====
NvMMLiteBC : Block : BlockType=4

Then show all black windows.

I also tryp gst-launch-1.0, but can not open camera too.

hello jahx1568,

let’s narrow down the issue, are you able to use v4l standard IOCTL to access to the steam?

How to use v4l standard IOCTL?

hello jahx1568,

please refer to developer guide, Applications Using V4L2 IOCTL Directly.

Thanks for your explain.
I aslo try this way to stream video.
But get the same error as gst-launch-1.0 about argus error

hello jahx1568,

this meant the port bindings is correct. so the video node is register to linux kernel.
the problem now should be on sensor side, doubt the sensor signaling is not sending out, or incorrect timing for CSI bricks.

are you using rbpcv2-imx219 cameras?
we’ve test this combination locally and it works normally. is it possible for moving to the latest Jetpack release version for confirmation?

Hello, JerryChang

I am using imx219.
Do you mean update jetpack to 5.1.0?

hello jahx1568,

which imx219, is it raspberry pi v2?
yap, please moving to Jetpack-5.1.0 if that’s possible.
