Hi，

We have developed a custom carrier that uses I225-IT for jp6.2. it’s not work. when I executed the command “lsmod | grep igc“, I don’t get any information. But it’s ok for jp5.2.

Based on the provided context, it appears that you are experiencing issues with the Intel I225-IT Ethernet controller on your custom carrier board, specifically with the Jetson AGX Orin module.

The lsmod | grep igc command is used to check if the igc driver is loaded, which is responsible for the Intel I225-IT Ethernet controller. Since you don’t see any information, it suggests that the driver is not loaded or not functioning correctly.

Comparing your setup to the provided context, I notice that the Jetson AGX Orin reference carrier board (P3737-0000) is mentioned, but it does not specifically mention the Intel I225-IT Ethernet controller. However, it does mention that the Jetson AGX Orin Dev-Kit Module (P3701-0000) and Jetson AGX Orin 32GB-DRAM (P3701-0004) modules are compatible with the reference carrier board.

To troubleshoot the issue, I would recommend checking the following:

  1. Device Tree: Verify that the device tree for your custom carrier board is correctly configured to support the Intel I225-IT Ethernet controller. You can refer to the “AGX Orin Device Tree Structure” section in the adaptation guide for more information.
  2. Kernel Configuration: Ensure that the kernel configuration for your Jetson AGX Orin module includes the necessary options to support the Intel I225-IT Ethernet controller. You can refer to the “Jetson Linux Toolchain” section for more information on kernel configuration.
  3. Driver Loading: Try loading the igc driver manually using the modprobe igc command to see if it makes any difference.
  4. JP62 vs. JP52: Since you mentioned that it works for JP52 but not JP62, it’s possible that there’s a configuration or hardware issue specific to JP62. Double-check your carrier board design and configuration to ensure that JP62 is correctly configured to support the Intel I225-IT Ethernet controller.

If none of these troubleshooting steps resolve the issue, it may be helpful to provide more information about your custom carrier board design, kernel configuration, and device tree configuration to further assist with debugging.

Please enable vendor driver from kernel manually.

Looks like PCIe already detected device.
