Hi,
1.Is the nano module eeprom information in the i2c bus2 0x50?
2.I use i2ctool dump bus2 0x50, then I find the output about eth mac addr is different with it in ifconfig.
The following is outputs:
sudo i2cdump -f -y 2 0x50

Before I get the right output with TX2(bus7 0x50), but now it seems have some questions with nano(bus2 0x50).
I want to see and assign mac addr about nano, please help me.
Thanks.
