How can i read the MAC Address of ENET controller?

Hi,

I have a question about MAC address.

I'm developing a project using Tower system and I know that I can use the MAC address written by Freescale under the controller module.

My question is: when I will have the "final" hardware with freescale component with ENET controller "inside", where can I read (by software!) the unique Mac Address?

Does Freescale give me an address in some EEPROM or something like this?

Regards,

Daniele

See MAC address

As explained there it is necessary to purchase a block from the IEEE. (Some people may prefer to purchase something like a MAC address EEPROM chip. Memory Products Home )

The Kinetis have a "program once" area in Flash which is suitale for storing the MAC address in. The uTasker project supports this method (as an option) as well as allowing management of the address via web browser as show in the following image.

Thank you Mark.

I was sure that it's not possible to sell a controller without a MAC address, I was wrong!
