Part Number: TMS320DM8168

Hi Sir

Please help to check, whether each single DaVinci device(we use DM8168) is factory programmed with unique MAC ID?

Thanks for your great support, wait for you.

    Hi Cyan,

    Every DM816x device comes with a unique MAC address.

    Ethernet MAC Address (MAC Address)— A unique 6-byte address that identifies an Ethernet device on the network. In an Ethernet packet, a MAC address is used twice, first to identify the packet’s destination, and second to identify the packet’s sender or source. An Ethernet MAC address is normally specified in hexadecimal, using dashes to separate bytes. For example, 08h-00h-28h-32h- 17h-42h.

    The first three bytes normally designate the manufacturer of the device. However, when the first byte of the address is odd (LSB is 1), the address is a group address (broadcast or multicast). The second bit specifies whether the address is globally or locally administrated (not considered in this document).
