CSI camera on jetson nano custom carrier board issue

Hi,
On our custom carrier board for jetson nano we have designed 4x 2-line CSI camera connectors. CSi lines are connected to CSIA,C,E,F ports. Camera’s I2C-s are multiplexed by TCA9548 multiplexer on address 0x70. I wrote custom device tree according to the patterns: “…camera-e3333-a00.dtsi”, “…camera-rbpcv2-dual-imx219.dtsi” and 'Camera development’section of NVIDIA Jetson Linux Driver Package Developer Guide. After system start I can see camera in /dev as video0 but I can’t open video stream. For testing puposes I’am using camera with imx219 sensor, which was tested with nano developer kit(A02) and everything worked well.

Here are some outputs:

When I use gst-launch, “No cameras available” error appears. I enabled debug messages for vi2_fops.c csi2_fops.c, imx219.c, and set logslevel print from level 8, but I can’t see any error logs in terminal.

So in conclusion:
Q1: Why I can’t see drivers error logs in terminal ?
Q2: How do I proceed with debuging this problem ?

Thank you very much for any help.

Regards Tom.

Set the below environment before run the gst-launch.

export DISPLAY=:0

Hi, thank you for your quick reply.

I just tried it:

root@ubuntu:~# export DISPLAY=:0 
root@ubuntu:~# gst-launch-1.0 nvarguscamerasrc ! nvoverlaysink

but there is still “No cameras available” error.

  1. Did you connect HDMI display? What the xrandr command show.
  2. Did you modify the position in the device tree as below.

https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fcamera_sensor_prog.html%23

        compatible = "nvidia, tegra-camera-platform";
        modules {
            module0 {
                badge = "imx185_bottom_liimx185";
                position = "bottom";
                orientation = "0";
                drivernode0 {
                    pcl_id = "v4l2_sensor";
                    devname = "imx185 30-001a";
                    proc-device-tree =

                };
            };
        };
    };
  1. No I’m working from ubuntu host pc through SSH connection.
  2. For position in device tree I used labels of six-cameras system (“bottomleft”) for camera0
    (test1 is my uboot board name )

I’m enclosing my device tree files:

Modify the bus number of devname to match the kernel report. From 30 - 33

devname = “imx219 0-0010” --> devname = “imx219 30-0010”

And use fakesink instead of nvoverlaysink.

gst-launch-1.0 nvarguscamerasrc ! fakesink

Oh, such a stupid mistake. Thank you so much ShaneCCC ! Now everything works fine.

Regards,

Tom.

Happy to hear the problem was fixed for you.

How do you apply the changes to the dtsi files?

Is this the right procedure to follow (complete kernel rebuild) or is there a simpler way?
https://developer.ridgerun.com/wiki/index.php?title=Jetson_Nano/Development/Building_the_Kernel_from_Source

@cpg_TO
Have a check the l4t document first.

https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fkernel_custom.html%23

I know this should be basic for most people but I can’t figure it out. I am lost in step 5.

5.Replace <release_packagep>/Linux_for_Tegra/kernel/Image with a copy of:
$TEGRA_KERNEL_OUT/arch/arm64/boot/Image
6.Replace the contents of Linux_for_Tegra/kernel/dtb/ with the contents of:
$TEGRA_KERNEL_OUT/arch/arm64/boot/dts/

Where am I supposed to put the Image and the dts files? I don’t see “<release_packagep>/Linux_for_Tegra/kernel/Image” anywhere. The only Image and dts that I have are on /boot.

Did you install the BSP via sdkmanager?
The package was download by sdkmanager and the path is configure by it too. Check the sdkmanager to find it out.

With that, I was able to do the whole thing, and I can see cameras 1 and 2 via gst-launch (nvarguscamerasrc sensor-id=0 and sensor-id=1).

If I try to open the cameras 3 and 4, I get the following error:

Error generated. /dvs/git/dirty/git-master_linux/multimedia/nvgstreamer/gst-nvarguscamera/gstnvarguscamerasrc.cpp, execute:536 Invalid camera device specified 2 specified, 1 max index

Do I have to edit libargus (can’t find gstnvarguscamerasrc.cpp anywhere)? Is there any alternative to open the other channels (v4l2)?

First make sure the video node are created. (/dev/video3/4)
If the video node are created than check the device tree of the tegra-camera-platform if any problem.
You can use dtc to get the device tree to confirm.

sudo dtc -I fs -O dts -o extracted_proc.dts /proc/device-tree
