TMS320C66x default mac address

Deniz Kocak

Hi All,

I wonder if TMS320C66x DSP comes with a unique MAC address from the factory production. In http://www.ti.com/lit/ds/sprs691c/sprs691c.pdf Section 7.21 (GbE) says "Each device has a unique MAC address, what does that mean? If there is no factory default MAC address, what are the possible ways of assigning one by the help of an API or tools?

Regards

    Deniz,

    By industry standards, you do not use a 'Default MAC Address'. Using the same mac address re-used is not allowed on commercial devices as they are required to be unique per device.

    Each C66x device is programmed with a Unique MAC Address out of Texas Instruments allotment of MAC addresses.  You can determine what the MAC Address is for your device by reading the MACID1/MACID2 registers on your device.  This, along with the address of these registers are defined within your devices data manual. 

    That said, you can program whatever MAC address you want, the MAC Source Address that's programmed is used to tell the MAC where to go get it's MAC address.  Normally this is programmed to the address of the provided Unique MAC Address.  But some developers who have their own block of MAC ID's may chose to user their MAC ID's.

    Best Regards,

    Hi Chad,

    I used the word "default" in a wrong way (I meant whether a unique MAC address is assigned out of the production), but your answer is what I am looking for. "Each C66x device is programmed with a Unique MAC Address out of Texas Instruments allotment of MAC addresses" sentence explains all. Thank you.
