Argus does not detect sensors

liviolima80 · February 5, 2025, 2:53pm

Good morning,
I have a commercial carrier board for Orin Nano and NX with 4 sensor camera ports configure as 2 lane camera port. At the moment I have connected only 2 ports to a custom sensor board based on Sony IMX715.
I’m using Jetpack 6.1, and sensor driver and DT overlay seems correct since I have

v4l2-ctl --list-devices
NVIDIA Tegra Video Input Device (platform:tegra-camrtc-ca):
/dev/media0

vi-output, imx715 10-001a (platform:tegra-capture-vi:1):
/dev/video0

vi-output, imx715 12-001a (platform:tegra-capture-vi:3):
/dev/video1

If I try to capture frames with
v4l2-ctl -c bypass_mode=0 --stream-mmap --stream-count=100 -d /dev/videoX
everything works correctly

If I try to capture frame using argus framework I have something strange. First of all I have the following

nvargus_nvraw --lps
nvargus_nvraw version 1.16.0
Number of supported sensor entries 1
Entry Source Mode Uniquename Resolution FR BitDepth Mode
Index Index Index CSI Dyn Type
0 0 0 dsboard_topleft_ornx 3864x2192 14 10 10 Bayer

When I run this command I have the following output to argus-deamon

With Argus I’m able to see and use only one camera.

The section of DT overlay related to “tegra-camera-platform” is the following

modules {
module0 {
status = “okay”;
badge = “dsboard_bottomleft_ornx”;
position = “bottomleft”;
orientation = “1”;

};
};
module1 {

};

};
};
module3 {

};
};

Could you help me to understand the problem?

Hi @liviolima80

Sometimes when v4l2-ctl capture works but not nvargus capture, it’s because the device-tree has some errors. Could you share your device-tree?

Also, from your log it seems you are using a custom isp config file. It could be that your isp config file is does not work as expected with more than one cameras.

---- imager: Found override file [/var/nvidia/nvcam/settings/camera_overrides.isp]. ----

Could you try removing that file?

Hi @enrique.ramirez ,
yes the isp is custom, but I have already use it in a 4-camera configuration with Orin AGX (with Jetpack 5.1.4) and 4 IMX675 cameras and it worrked.

By the way I tried to remove all the files in /var/nvidia/nvcam/settings/, reboot the board but anything changed, nvargus_nvraw detect only 1 camera.

Furthermore, this is another useful output

Just to confirm, you can capture images from both /dev/video0 and /dev/video1 ?

v4l2-ctl -c bypass_mode=0 --stream-mmap --stream-count=100 -d /dev/video2
v4l2-ctl -c bypass_mode=0 --stream-mmap --stream-count=100 -d /dev/video1

According to your log, it seems that module0 is fine, but there’s a problem with module1:

OFParserListModules: module list: /proc/device-tree/tegra-camera-platform/modules/module0
OFParserListModules: module list: /proc/device-tree/tegra-camera-platform/modules/module1
OFParserEnumerateDriverNode: v4l2_sensor: failed to parse device-tree to driver node
OFParserListModules: module list: /proc/device-tree/tegra-camera-platform/modules/module2
OFParserListModules: module list: /proc/device-tree/tegra-camera-platform/modules/module3

Checking your media-ctl output it looks like only the cameras on 10-001a and 12-001a are available (you connected only 2).

...
← “imx715 10-001a”:0 [ENABLED]
pad1: Source
→ “vi-output, imx715 10-001a”:0 [ENABLED]
...
← “imx715 12-001a”:0 [ENABLED]
pad1: Source
→ “vi-output, imx715 12-001a”:0 [ENABLED]
...

These match to module0 and module3. As module1 is not connected, the nvargus_nvraw may complain.

Have you tried capturing using GStreamer?

gst-launch-1.0 nvarguscamerasrc sensor-id=0 ! 'video/x-raw(memory:NVMM), width=(int)3864, height=(int)2192,format=(string)NV12, framerate=(fraction)30/1' ! fakesink silent=false -v

Hi @enrique.ramirez ,
after your comment I realized that there were some error in DT file only for module1, so I checked agin the DT and I found the problem. The part relative to sensor parameters was

i2c@3180000 {
pca9544a_70: pca9544a@70 {
status = “okay”;
force_bus_start = <CAMERA_I2C_MUX_BUS(0)>;

			i2c@0 {
				reg = <0>;
				i2c-mux,deselect-on-exit;
				imx715_a@1a { ..... }
                            };
                            i2c@1 {
				reg = <1>;
				i2c-mux,deselect-on-exit;
				imx715_a@1a { ..... }
                            };
                            i2c@2 {
				reg = <2>;
				i2c-mux,deselect-on-exit;
				imx715_c@1a { ..... }
                            };
                            i2c@3 {
				reg = <3>;
				i2c-mux,deselect-on-exit;
				imx715_d@1a { ..... }
                            };

}

so the i2c@1 module was defined as imx715_a@1a instead of imx715_b@1a. After fixing this problem everything works!
The strange thing is that v4l2 doesn’t matter about this error. If I run
v4l2-ctl -c bypass_mode=0 --stream-mmap --stream-count=100 -d /dev/video0
v4l2-ctl -c bypass_mode=0 --stream-mmap --stream-count=100 -d /dev/video1
before fix the problem, both the sensors worked

By the way, thanks for your support
Regards

Oh that’s good news!
What I have seen is that if something defined on tegra-camera-platform node is wrong, nvargus capture (using ISP) doesn’t work. However, this doesn’t affect the v4l2 raw capture which doesn’t use the ISP
