What approach should be taken to use the CAN interface on the AGX orin development kit, since the CAN interface has only one pin for input and output in the 40-Pin Expansion Header, do I need to use a special adapter cable, or how do I configure it?

To use the CAN interface on the AGX Orin development kit, you’ll need to consider the limitations of the 40-Pin Expansion Header, which has only one pin for input and output. Here’s a step-by-step approach to help you configure and utilize the CAN interface:

  1. Understand the CAN interface: The CAN (Controller Area Network) interface is a network interface for CAN devices. It’s essential to familiarize yourself with the CAN protocol and its requirements.
  2. Check the documentation: Refer to the AGX Orin development kit documentation, specifically the section on the 40-Pin Expansion Header. This will help you understand the pinout and any specific requirements for using the CAN interface.
  3. Use a special adapter cable: Given the single pin for input and output, you may need to use a special adapter cable to split the signal into separate input and output lines. This will depend on your specific use case and the requirements of your CAN device.
  4. Configure the CAN interface: You’ll need to configure the CAN interface on the AGX Orin development kit. This may involve setting the baud rate, configuring the CAN controller, and enabling the interface. You can use tools like ip link to manage network interfaces, including the CAN interface.
  5. Test the CAN interface: Once you’ve configured the CAN interface, test it using a loopback test or an oscilloscope to ensure it’s working correctly.

Comparison with other Jetson modules:

  • The Jetson Orin NX module has a similar 40-Pin Expansion Header, but it’s essential to check the documentation for specific differences in pinout and configuration requirements.
  • The Jetson TX2 module has a different CAN configuration and suspension issues, which may not be directly applicable to the AGX Orin development kit.

Additional considerations:

  • If you’re using a PCAN driver, you may need to set up the driver specifically for the AGX Orin development kit.
  • Be aware of any issues related to CAN from SPE (System-on-Chip) on Jetson Orin Nano, as these may impact your configuration.
  • If you’re using Jetpack6, ensure that you’re aware of any limitations or issues related to peak_can device support.

In summary, to use the CAN interface on the AGX Orin development kit, you’ll need to understand the CAN protocol, check the documentation, use a special adapter cable if necessary, configure the CAN interface, and test it thoroughly. Be aware of any specific requirements and limitations of your setup, and consult the documentation and additional resources as needed.
