JP 7.1 R3840 camera如何加载nito文件

mingming · July 29, 2026, 6:31am

hi：

我们在R3840上调试一款raw相机，通过如下命令，找不到sensor，之前的帖子说是缺失nito文件，现在原厂提供了nito文件，我们要如何配置，让系统加载这个文件呢

nvargus_nvraw --lps

You need check with partner to generate the nito file from binary.cfg

Thanks

hi：

他们只提供了nito文件，现在的疑问是系统如何加载nito 然后能让命令找到sensor呢

zedx_ar0234.nito 这个文件是他们提供的

To apply a .nito file on Jetson Argus:

Copy the .nito file to /var/nvidia/nvcam/settings on the device. This is the standard location used in the migration flow.
Use one of these two ways to load it:
- Auto-discovery: if a NITO is not explicitly specified, the stack uses the module name / badge name to identify and pick the right NITO.
- **Force a specific file**:
```
export NVCAMERA_NITO_PATH=/var/nvidia/nvcam/settings/your_file.nito
```
  then restart nvargus-daemon.

Restart Argus:

sudo systemctl stop nvargus-daemon
sudo -E /usr/sbin/nvargus-daemon &

Then run argus_camera or nvargus_nvraw.

Verify it is loaded in daemon logs. You should see messages like:
- Using NITO ...
- Finished loading config data from NITO knobset ...

If it still does not take effect

Delete cached .bin files under /var/nvidia/nvcam/settings before retrying.
If auto-discovery fails, use NVCAMERA_NITO_PATH first to confirm the NITO itself is valid.

Example:

sudo cp my_sensor.nito /var/nvidia/nvcam/settings/
export NVCAMERA_NITO_PATH=/var/nvidia/nvcam/settings/my_sensor.nito
sudo systemctl stop nvargus-daemon
sudo -E /usr/sbin/nvargus-daemon &
argus_camera

The log doesn’t looks like relative to .nito file loading problem.

Do you confirm the sensor driver is probing succesfully?

hi：

我看驱动加载了，通过以下命令可以抓帧率

我们修改了module名字，现在开机能看到加载isp和nito了，还是有其他报错，帮忙看看是哪里的问题

Looks like the sensor mode didn’t match with the nito file.

This might help diagnose:

# Second terminal
sudo nvargus_nvraw --sensorinfo

Make the sensor mode in device tree and driver the same with .nito file.

hi：
在sensor的设备树和驱动中加了一组，还是有报错
如下配置：

        csi_pixel_bit_depth = "8"; \
        mode_type = "bayer"; \
        pixel_phase = "rggb"; \

This error usually means the ISP7 NITO content is bad, not that the sensor link is broken.

The closest internal match for this exact sequence—

failed to open CamPg QM handle
Cannot create ISP7 merger
Argus / nvargus_nvraw init failure

—was root-caused to a copy-paste error in the NITS/NITO lens shading parameters. In that case, the log also showed LSC surface is not based on full res!, and the fix was to correct the lens shading knob image resolution / LSC parameters in the NITS file and regenerate the NITO.

What this means

Argus got far enough to start ISP initialization.
It failed when ISP7 tried to create the CamPg QM handle from the NITO knobs.
So the likely problem is inside the NITO, especially LSC / lens shading / CamPg knob data, not a CSI transport issue.

What to check first

Lens shading / LSC block in the NITS/NITO
- verify the LSC surface is based on the full resolution
- verify no copied wrong dimensions from another mode/sensor
Regenerate the NITO
- convert .nito → .nits
- fix the LSC section
- rebuild .nito
