Xavier AGX EEPROM Layout

Hi All,

I would like to keep a user critical data (around 6 bytes) in the Xavier AGX EEPROM. We would like to know if there is any memory region allocated for user data which wont be utilized by Nvidia in the future. Please, kindly share the memory layout of the EEPROM in Xavier AGX.


please check developer guide, Jetson Module EEPROM Layout.

Can we use the 172–177 memory region in the EEPROM to have additional user defined MAC address? Will writing values to these registers cause any other result in Nvidia working?

Yes, you can change the MAC address.

But please remember to update CRC checksumi bit 255 in the eeprom after you change anything, then you shall not crash other board.
