How to write custom ETH MAC address to Orin Nano/NX with customer board?

Hi NV team

Now we are thinking about how to write our own ethernet MAC address into our custom carrier board(without EEPROM as devkit), do you have some tools or command to realize that requirement?

Thanks!

Orin NX/Nano ethernet mac is fused in the PHY directly. You need to contact Realtek for the tool so that you can modify it.

They are not read from EEPROM.

Got it.

Beside, how to config the Orin Nano/NX devkit RJ45 LED control since our custom carrier board design with same circuit as devkit, and our RJ45 LED sounds not OK(target: 10M/100MHz green led off, 1000MHz green led on; yellow led flash when data active).

This is also inside the realtek driver r8168. To program it, a realtek datasheet for this PHY is also needed.

This needs to get from Realtek as well. NV cannot release it.

OK, thanks!
