How to let jetson Xavier NX to get its correct MAC address?
Thanks!

Hi,

The MAC address is read from the eeprom. If it fails to read from eeprom, probably means you corrupted the eeprom or the i2c has some problem so it cannot read.

Please share the cboot log from serial console.

Hi,

It is more like a hardware issue.

Please try to re-flash your board with different release (e.g. rel-32.3.1/rel32-4.2/rel-32.4.3) and see if any of them is able to read the i2c value from eeprom.

If none of them can read it, please RMA your Xavier.

Thanks.Let me try.
And How to read the serial-number of Xavier NX.
Jetpack 4.2 I can read it by this:
cat /sys/firmware/devicetree/base/serial-number
But the file is not exist on Xavier NX Jetpack 4.3

serial number is also from eeprom…

If the device has defect, then you are not able to read the serial number either.

cat /sys/firmware/devicetree/base/serial-number

The file exists on Jetpack4.4. Maybe your board does not have it because of the hardware defect.

nvidia@nvidia-desktop:/sys/firmware/devicetree/base$ ls serial-number
serial-number

This is the result from my board.
