Hello,

Now , i am trying to make EtherCAT system on Jetson orin nano. i’m not sure that it can be succeeded. because NIC chipset of Jetson orin nano developer kit is from RTL. RTL has weakness to do EthercAT communication. If in this kind of case, what can i do? Is there anyone who has solution?

I understand your concern about using the Jetson Orin Nano for EtherCAT communication due to the NIC chipset being from Realtek (RTL). While RTL chipsets are widely used, they may not be the best choice for EtherCAT applications.

EtherCAT is a high-performance, low-latency industrial Ethernet protocol that requires precise timing and synchronization. The NIC chipset plays a crucial role in ensuring reliable and efficient communication.

If you’re experiencing issues with the RTL chipset on the Jetson Orin Nano, here are a few potential solutions you could consider:

  1. Use a different NIC: You can try using a different NIC (Network Interface Card) that is specifically designed for EtherCAT applications. Some popular options include Intel or Broadcom-based NICs, which are known for their better performance and reliability in industrial Ethernet applications.
  2. Use a USB-to-EtherCAT adapter: If replacing the NIC is not feasible, you can consider using a USB-to-EtherCAT adapter. These adapters can provide a dedicated EtherCAT interface and may offer better performance and reliability than the built-in NIC.
  3. Optimize the system configuration: Ensure that your system configuration is optimized for EtherCAT communication. This includes setting the correct network settings, disabling unnecessary network protocols, and configuring the EtherCAT master and slave devices correctly.
  4. Use a different EtherCAT master: If you’re using a software-based EtherCAT master, you can try using a different master that is optimized for the Jetson Orin Nano’s hardware. Some popular EtherCAT master software includes TwinCAT, EtherCAT Master, or SOES.
  5. Consult with NVIDIA or RTL: Reach out to NVIDIA or Realtek support to see if they have any specific recommendations or patches for improving EtherCAT performance on the Jetson Orin Nano.

It’s worth noting that the Jetson Orin Nano is a powerful platform, and with the right configuration and setup, it’s possible to achieve reliable EtherCAT communication. However, if you’re experiencing persistent issues, it may be worth exploring alternative solutions.

In comparison, the Jetson AGX Orin has a more robust NIC chipset, which may be better suited for EtherCAT applications. However, the AGX Orin is a more powerful and expensive platform, so it’s essential to weigh the costs and benefits before deciding on a solution.

I hope this helps you find a solution for your EtherCAT system on the Jetson Orin Nano!

Not sure what your concern is? Could you share more details on the issue?

You could use PCIe NIC or USB3 to ethernet dongle/module and connect to Jetson Orin Nano, if required.
