Questions about default MAC address generation mechanism of Jetson Orin Nano

Robotics & Edge Computing Jetson Systems Jetson Orin Nano

I have observed various descriptions in the forum regarding how the Jetson Orin Nano obtains its default MAC address, and some of them are contradictory. For example:

1.The Jetson Nano does not support modifying the default MAC address via EEPROM; instead, a Realtek tool should be used to operate directly on the PHY.
2.The Jetson Nano can configure the default MAC address through the EEPROM (i2c-2, 0x50).
What is the actual situation?

This link mentions that the Jetson Nano does not support modifying the default MAC address via EEPROM.

However, according to the instructions in this link, it seems that the default MAC address of the Jetson Nano can be configured via EEPROM (i2c-2, 0x50).

One is Jetson Nano, the other is Jetson Orin Nano, they’re difference products.
So your question is for Orin Nano, and the answer at Orin Nano – How to Modify Default MAC Address from EEPROM - #2 by WayneWWW is correct.

Thank you for your quick and accurate response. Could you please introduce how to modify the default MAC address of the Jetson Orin Nano using Realtek tools?

Please contact Realtek for the tool to modify it.
