Based on the provided context, I’ll try to help you troubleshoot the issue with your Nvidia Jetson AGX Orin Developer kit and the LIVenus IMX623 GMSL2 cameras.
Hardware and Software Setup
You have an Nvidia Jetson AGX Orin Developer kit, which is a powerful platform for AI and computer vision applications. You also have the LIVenus IMX623 GMSL2 cameras from Leopard Imaging, which are high-quality cameras designed for various applications. Additionally, you have the following adapter and carrier board:
- LI-JTX1-SUB-ADPT (Adapter)
- LI-JXAV-MIPI-ADPT-4CAM-V1.01 (Carrier Board)
- LI-MAX9296-IPX-DESER-V1.01 (Deserializer)
- 12VDC Power supply on the Jetson R3531 is installed
You have installed the driver according to the instructions, but unfortunately, neither the camera nor the deserializer is recognized by the Jetson. The nvgstcapture-1.0 command displays the error message “no camera available.” I2C communication with the devices is also not possible.
Possible Causes
Based on the provided information, here are some possible causes for the issue:
- Hardware Connection Issues: Double-check the connections between the camera, deserializer, and the Jetson AGX Orin Developer kit. Ensure that all cables are securely connected and that there are no loose connections.
- Power Supply Issues: Verify that the 12VDC power supply is sufficient for the camera and deserializer. Check the power consumption of the devices and ensure that the power supply can provide enough power.
- I2C Communication Issues: I2C communication is not possible, which could indicate a problem with the I2C bus or the devices connected to it. Check the I2C bus configuration and ensure that the devices are properly configured.
- Driver Issues: Although you have installed the driver according to the instructions, there might be an issue with the driver itself. Check the driver version and ensure that it is compatible with the Jetson AGX Orin Developer kit and the LIVenus IMX623 GMSL2 cameras.
- Device Tree Issues: The device tree might not be properly configured, which could prevent the camera and deserializer from being recognized. Check the device tree configuration and ensure that it is correct.

Conclusion
To troubleshoot the issue, I recommend checking the hardware connections, power supply, I2C communication, driver version, and device tree configuration. If none of these solutions work, you can try to apply the solutions provided in similar issues reported by other users. If you are still unable to resolve the issue, you may want to consider seeking further assistance from Nvidia or Leopard Imaging support teams.
