How to solve same mac address

I bought 5 Jetson Nanos.

among the Jetson Nanos, I have a same mac address on two jetson nanos.

so, i can’t assign static Ip address.

How to solve this problem?

cansee5744,

Could you share the mac addr of that two nano? Need to check if it is using default (hard-coded) value because of some eeprom errors.

If the boards have the same MAC address, you can apply this patch:
