The issue has been resolved. Thank you for your help.

I am sorry, the camera ID vs slot ID may be a bit confusing when you first start playing with camera configurations.

In your case you only have one camera plugged into Camera Hardware Slot 2, (so you use the sensormodule with index 2), but once the cameras are detected by the system, they are assigned with camera ids which start with 0. So in your configuration file, you need to set camera_id to 0 and it should be called camera_id, not camId. -- you actually have both of those, so please remove camId and camId2 entries, and just set camera_id to 0.

You also have some duplicate (incorrectly named) parameters such as pre_width and pre_height -- the correct ones are preview_width and preview_height, which are also there. I think you probably got those from the information that camera server prints out when it starts, which actually does not use correct parameter names, such as camId and pre_width, etc... We should fix that..

I'm having an issue where the IMX412 camera connected to J7L (camera slot 2) is detected but the camera server fails to start.

• Solutions Already Attempted:
  a) Sensor Module File Modification:
  - Copied /usr/share/modalai/chi-cdk/imx412-fpv/com.qti.sensormodule.imx412_fpv_2.bin to
  - /usr/lib/camera/ directory

  b) Configuration File Modification:
  - In /etc/modalai/voxl-camera-server.conf
  - Set camId and camera_id to 2
  - Disabled MISP-related settings (en_misp: false, misp_venc_enable: false)

• Current Status:

• Problem Summary:

  • Camera sensor is successfully detected (sensor_id:0x577)
  • Correct sensor module file (imx412_fpv_2.bin) is installed
  • Configuration file has camId and camera_id both set to 2
  • MISP-related settings are all disabled
  • However, camera server fails to start and userspace process terminates

• Additional Attempts Made:

  • Restarted camera server (systemctl restart voxl-camera-server)
  • Ran in debug mode (voxl-camera-server -d)
  • Checked system logs (dmesg | grep -i cam)
  • Disabled MISP-related settings

Are there any additional suggestions or things I should check to resolve this issue?

Do not worry about the following print statement, it is not fatal : ERROR: object missing misp_channels

Alex

In /usr/lib/camera/, only IMX412-related sensormodule files were kept; others were deleted.
/etc/modalai/voxl-camera-server.conf was configured for a single IMX412 (hires) camera.
voxl-camera-server was run in both foreground and debug modes.

I'm wondering if there are any additional areas I should check, or if there are any known issues related to the IMX412 (M0107) module, slot, or firmware. Also, if anyone has resolved similar symptoms, please share your experience.

Your VOXL2 SW is likely set up for different camera configuration and you have a non-standard single camera setup (your IMX412 is connected to J7L, which is camera slot 2).

Considering that voxl-camera-server -l is already detecting your camera, you can confirm that it is IMX412 based on the sensor ID (also in docs above). The i2c read errors are coming from trying to detect cameras which are not physically connected (0x356 is the WHOAMI register value of AR0144 camera, which you do not have connected to your voxl2).

If you look in your /usr/lib/camera/, you should only have an imx412 sensormodule with slot 2 (com.qti.sensormodule.imx412*_2.bin) and if you don't want to see the i2c probe errors, you can remove other sensormodules from that directory (however they should not hurt, since you are already detecting your IMX412 camera, it seems).

You also need to take a look at your /etc/modalai/voxl-camera-server.conf and confirm it is correctly set up for a single hires imx412 camera. Then run voxl-camera-server in foreground to see any error messages.
