Nvargus-daemon does not start camera feed on Nano

vsaw · February 4, 2021, 3:34pm

Hi there,

since a few days ago, I can not get a camera feed anymore on my Jetson Nano.

Setup

Jetson Nano 4GB
JetPack 4.3 (R32 (release), REVISION: 3.1, GCID: 18186506, BOARD: t210ref, EABI: aarch64, DATE: Tue Dec 10 06:58:34 UTC 2019)
IMX219 Camera connected via CSI

Camera Pipeline

I use gst-launch1.0 to access the camera feed as follows

gst-launch-1.0 \
    nvarguscamerasrc sensor-id=0 ! \
    "video/x-raw(memory:NVMM), width=1280, height=720, format=(string)NV12, framerate=(fraction)120/1" ! \
    videorate max-rate=10 ! \
    nvvidconv flip-method=2 ! \
    jpegenc ! \
    rtpjpegpay ! \
    queue leaky=downstream max-size-buffers=1 ! \
    udpsink host=127.0.0.1 port=7001

The output of this command is

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...

GST_ARGUS: PowerService: requested_clock_Hz=24192000
GST_ARGUS: Setup Complete, Starting captures for 0 seconds
GST_ARGUS: Starting repeat capture requests.
CONSUMER: Producer has connected; continuing.

However my application receives no frames. This behavior is consistent across reboots.

Additional Information

Debug Logs

Looking at /var/log/sysctl I get a lot of error messages from nvargus-daemon. I’ve included a few of them in the attachment. Also dmesg complains a lot about syncpts.

dmsg.txt (18.9 KB)
syslog-nvargus-daemon.txt (8.1 KB)

Final Remarks

As mentioned in the beginning: The gstreamer pipeline was working until a few days ago. I am not aware of any changes in my setup that caused the camera to stop working.

An pointers on what I should try to fix this are greatly appreciated!

Have reference to below doc to verify sensor working well. If not that could be the HW or connection problem.

Thanks @ShaneCCC for the quick reply. From what I can tell the HW connection is fine. v4l2-compliance does produce one failure, but I get the exact same output on another device where the camera is working fine.

Update

I thought that CSI cameras are not available on v4l2. See for example: Jetpack 4.5 CSI cam can't use with v4l2 /dev/video0 - #3 by JerryChang

ShaneCCC · February 5, 2021, 9:58am

Check with this command. And enable the debug print of the csi2_fops.c to check the status.

v4l2-ctl --stream-mmap --stream-count=100 --set-ctrl bypass_mode=0 -d /dev/video0

vsaw · February 5, 2021, 10:33am

Thank you @ShaneCCC .

I’m not sure how to enable the debug prints, but running the command directly produces the following output:

First Try

$ v4l2-ctl --stream-mmap --stream-count=100 --set-ctrl bypass_mode=0 -d /dev/video0 --verbose
VIDIOC_QUERYCAP: ok
VIDIOC_S_EXT_CTRLS: ok
VIDIOC_REQBUFS: failed: Device or resource busy

Second Try

I then rebooted the device and then it freezes with the following output:

$ v4l2-ctl --stream-mmap --stream-count=100 --set-ctrl bypass_mode=0 -d /dev/video0 --verbose
VIDIOC_QUERYCAP: ok
VIDIOC_S_EXT_CTRLS: ok
VIDIOC_REQBUFS: ok
VIDIOC_QUERYBUF: ok
VIDIOC_QBUF: ok
VIDIOC_QUERYBUF: ok
VIDIOC_QBUF: ok
VIDIOC_QUERYBUF: ok
VIDIOC_QBUF: ok
VIDIOC_QUERYBUF: ok
VIDIOC_QBUF: ok
VIDIOC_STREAMON: ok

On a different device with the same HW I get

$ v4l2-ctl --stream-mmap --stream-count=100 --set-ctrl bypass_mode=0 -d /dev/video0
<<<<<<<<<<<<<<<<<<<<<<< 21.15 fps
<<<<<<<<<<<<<<<<<<<<< 21.07 fps
<<<<<<<<<<<<<<<<<<<<< 21.05 fps
<<<<<<<<<<<<<<<<<<<<< 21.03 fps
<<<<<<<<<<<<<<

If you give me any pointers on how to enable the debug prints I’d be happy to try again.

ShaneCCC · February 5, 2021, 12:15pm

Run below command then run the v4l2-ctl and check the dmesg.

sudo su
echo file csi2_fops.c +p > /sys/kernel/debug/dynamic_debug/control

vsaw · February 5, 2021, 3:02pm

@ShaneCCC Done. Here’s what I have

$ v4l2-ctl --stream-mmap --stream-count=100 --set-ctrl bypass_mode=0 -d /dev/video0 --verbose
VIDIOC_QUERYCAP: ok
VIDIOC_S_EXT_CTRLS: ok
VIDIOC_REQBUFS: failed: Device or resource busy

Larger dmesg output attached: dmesg-device-busy.txt (5.0 KB)

After restarting `nvargus-daemon`

I restarted nvargus-daemon and ran v4l2-ctl again with the following dmesg output

The messages just keep repeating the last lines a few more times.

@ShaneCCC do you still need more infos from me? I’m still lost so any help is greatly appreciated.

ShaneCCC · February 12, 2021, 2:13am

I think need HW engineer help to check what’s the different for the failed device.

vsaw · February 15, 2021, 5:10pm

It looks like it was a HW error after all. With a different CSI-Cable the device starts up again. (I was only able to check this after the camera has been returned from the customer)

But I don’t know I was able to enumerate the Camera Resolution and other information with the broken cable in the first place 🤷‍♂️

Thank you @ShaneCCC for your support.
