DM355 MAC Address

Amer Abufadel5389

Greetings,

The Technical Reference of the EVM-DM355 states "The ethernet address is stored in the ethernet controller’s SPI ROM during manufacturing."

I am guessing that I can use a pre-programmed SPI  EEPROM with a unique MAC address?

 

Thank you,

 

Amer

    Yes, this should be supported.  The format for the EEPROM of the Davicom DM9000A ethernet controller is documented in Section 7 of the Davicom DM9000A datasheet.
    The first 6 bytes of the EEPROM image is the MAC address.

    Can I use an ethernet controller with a built in MAC instead of the EEPROM solution?  This would reduce space requirements.

     

     

    Thank you,

    I don't see any reason that you could not, however using a different Ethernet controller would mean that you probably have to modify the existing Ethernet driver for your new device, the advantage of using the same device as the EVM is software compatibility.
