AM3505 MAC

Hi

I'm reading the MAC address stored in CONTROL_FUSE_EMAC_LSB & CONTROL_FUSE_EMAC_MSB. The value I read is: 7c:8e:e4:xx:xx:xx. Is this a TI address? Is the address always unique?

I've read the same MSB value from several CPU's.

 

Regards

Øyvind

    The MAC address programmed into the AM35x device, via e-fuse, during final test will be a unique value for each device.

     

    A block of MAC addresses have been set aside for this device.  The next available MAC address is incremented after the previous value is programmed into a tested device.  Therefore, consecutive good devices would have incrementing MAC address.

     

    Regards,

    Since this MAC address is unique and belongs to TI, if we are using AM35x for mass production, can I use this address as the MAC address of our product?   If I cannot use it, where should I save the MAC address to make it persistent?
