Troubleshooting

1. Driver installation

Send us the output of the automatic installation script if you encounter problems during the installation process.

eg

install driver nvidia jetson nano nx

Note

At present, the drivers we provide only support official development boards.

2. Third-party boards and self-compiled kernels

At present, the drivers we provide only support official development boards. For third-party boards that need to modify the device tree by themselves, we will provide the source code.

3. The camera does not work

3.1. Camera not found

Execute the following command and find that there is no video device.

ls /dev/video*

9f37fb37379c49c59bb06ad706bcc44f3368

There are two situations that may cause no video equipment: (example for imx477)

a. Driver is not installed

To check whether the driver is installed, use the following command.

dmesg | grep -E "imx477|imx219|arducam"

ba7020ce040f4cbd9320f22a3d2952f53368

The driver of IMX-477 is installed if the output similar to the above figure, other drivers are installed if the output is arducam or IMX-219.

b. There is a problem with the hardware connection

It means that the camera is not detected if it is determined that the driver has been installed correctly and the probe failed in the dmesg log, similar to the following figure.

At this time, it is very likely that there is a problem with the connection (such as a loose cable, wrong connection method, and damaged cable). Please check whether the cable connection is loose. If so, try to replace a replaceable cable.

Note

You can see from the picture that there are [9-001a] and [10-001a] (7-001a and 8-001a for Nano), which represent two different camera interfaces. It is normal for the other to report errors if you only use one of them.

3.2. There is a video device that is not working

Execute the following command and find that there is a video device.

ls /dev/video*

5

Running Gstreamer.

SENSOR_ID=0 # 0 for CAM0 and 1 for CAM1 ports
FRAMERATE=30
gst-launch-1.0 nvarguscamerasrc sensor-id=$SENSOR_ID ! "video/x-raw(memory:NVMM),width=1920,height=1080,framerate=$FRAMERATE/1" ! nvvidconv ! nveglglessink -e

6

Run the dmesg command again.

dmesg

7

If similar output appears, it is very likely that there is a problem with the connection (such as a loose cable, wrong connection method, and damaged cable). Please check whether the cable connection is loose. If so, try to replace a replaceable cable.

4. How to adjust the Exposure Gain

Run the following command to view the available parameters of nvarguscamerasrc.

gst-inspect-1.0 nvarguscamerasrc

Set exposure.

gst-launch-1.0 nvarguscamerasrc aelock=true exposuretimerange='10000 10000' ! capsfilter caps='video/x-raw(memory:NVMM),width=(int)1920,height=(int)1080,format=(string)NV12,framerate=(fraction)30/1' ! nvvidconv flip-method=2 ! nveglglessink -e

Note

The theoretical exposure range is 0~1000000 / fps μs. For example, the exposure range of 30fps is 0~33333 μs. If the setting is larger than this range, it will be invalid. If you want to set a longer exposure time, please lower the frame rate.

Reference.

5. Mixed-use of cameras

You need to modify the device tree if you want to mix cameras, for example, CAM0 is IMX-477 and CAM1 is IMX-219.

We provide several examples for reference, but there are many such combinations and we cannot cover all cases. For this, you can choose to modify the device tree yourself by referring to the examples we provide or contact us for customization service.

6. Use SSD on Xavier NX

Xavier NX can not boot directly from SSD. Firstly, it needs to load the kernel from the SD card, and switch rootfs to SSD after booting. Therefore, if you install the driver in the rootfs of SSD, it will not change the kernel used at boot.

You can switch to SD card to install the driver or copy two files which patch of SSD is /boot/arducam and /boot/extlinux/extlinux.conf to the Corresponding catalog in SD card.

7. How to use maximum frame rate

The maximum frame rate of IMX477 is full resolution@60fps(normal), 4K2K@60fps(normal), 1080p@240fps.

However, use the maximum frame rate needs MIPI 4 lanes and D-PHY spec. ver. 1.2( or the later versions). From the technical manual, the carrier board of Jetson Xavier NX/Nano only has 2 lanes CSI2 interface.

In summary, you need to buy the third-party carrier board with 4 lanes CSI2 interface. Contact us to customize the driver if you need to drive Arducam IMX477 Camera.

Note

Due to Jetson Xavier NX/Nano hardware only supports 4K@30fps encoding, you cannot use it for 4k@60fps h.264/h.265 encoding.

8. How to view the controls supported by v4l2-ctl

v4l2-ctl -l

9. Cannot Install Camera Driver on Jetson Orin Nano/NX and Jetson AGX Orin

  • Verify Carrier Board Compatibility: Please ensure that you are using an official NVIDIA carrier board. Our drivers are not compatible with third-party carrier boards. If you are using a third-party board, this may be the cause of the issue.
  • Update to the Latest L4T Version: Flash your system to the latest L4T version 36.3.0. After updating, try installing the driver again. The latest updates may have resolved compatibility issues.

If you have tried the above steps and still cannot install the driver, please contact us at support@arducam.com for further assistance.
