I designed the Nano carrier board by myself, but the ethernet is missing. I tried to fix this issue by changing the eeprom configuration. I did following operations:
I chang the value in address 0x23 by I2C.
sudo i2cset -f -y 2 0x50 0x23 0x32
(According to this link: https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3231/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide%2Fjetson_eeprom_layout.html)
Then reboot the Nano.
The system is failed to reboot.
Would you please help to check and support this case. Thanks for support.
