You can see from the mac
and androidboot.mac
fields that the address is c8:63:14:70:43:e4

You can see from the ether
fields that the address is c8:63:14:70:43:e4
Setup Customer Ethernet MAC Address
khadas@Khadas:~$ sudo vim /boot/env.txt
Modify custom_ethmac
, customize it to the MAC address you want, the format is xx:xx:xx:xx:xx:xx
, for example, c8:63:14:70:43:e6
,
custom_ethmac=c8:63:14:70:43:e6
khadas@Khadas:~$ sync khadas@Khadas:~$ sudo reboot
Confirm whether the modification is effective

note :
If there is no custom_ethmac
field in boot/env.txt
, you can add it at the end.
The custom Ethernet must comply with the rules. If your custom URL does not comply with the rules, when you view it in the ifconfig
command, it will display a result that is different from your custom address.
