Troubleshoot Common Issues with Reference Image

This chapter describes some ways to fix problems you may encounter when you boot up your reference image. You should also take a look at the release notes for this product to check for known issues or limitations.

The camera service doesn't start:
Symptoms: When you restart your board, the camera service doesn't start. If you run the pidin command, you don't see the camera service running.
Suggested Resolutions: It 's possible that the configuration for the camera connected to your system is incorrect. Here are some ways you can resolve the problem:
- For cameras connected with an FPD-Link III interface, ensure that you have the proper port specified in the configuration file that maps back to the physical connection. For example, if you have a camera connected to the interface port 1, then the address property should match the interface port (e.g., address = ov10635_deser, 1). For more information, see Configuration for using less than four FPD-Link III interface cameras.
- If you are configuring a file camera, ensure that the video file exists and that the camera service has the proper permissions to read the file.
USB Camera isn't recognized:
Symptoms: You have a camera connected to the USB 2.0 or USB 3.0 ports on your Jacinto 6 EVM board. When you run your application using the Camera Framework, the camera doesn't seem to be recognized. This problem can occur when you call camera_get_supported_cameras() and the numSupported returns a zero - indicating that no cameras are supported.
Suggested solutions:
- The USB camera might not be properly configured or not supported and therefore, not recognized. Ensure that your camera is configured properly in the camera configuration file; otherwise, ensure that the USB camera is supported.
  For information about how to configure a camera, “see Configure cameras on the reference image”.
  
  For information about the camera configuration file, see “../../com.qnx.doc.adas.system_services/topic/camera_service_configuration_file.html” in the System Services guide.
  
  For information about the supported cameras, see “ Supported hardware configurations”
  .
- If you have optimized your image to delay the start up of the USB drivers until after the camera service starts (i.e., reference images), modify the /etc/slm-config-platform.xml file and move the usb block that starts the USB drivers before the block to start the camera service. For more information, see Configuration for using a camera connected via USB.
