This affects the size of memory initialized, network mac +address numbering, and tuning of the network PHYs. + +The Star64 does not currently ship with unique serial numbers per-device. +Devices follow a pattern where the last mac address bytes are a sum of 0x7558 +and the serial number (lower port mac0), or a sum of 0x7559 and the serial +number (upper port mac1). + +As tested there are several 4gb model units where the serial number and network +mac addresses collide with other devices (serial +``STAR64V1-2310-D004E000-00000005``, MACs ``6c:cf:39:00:75:61``, +``6c:cf:39:00:75:62``) + +Some early Star64 boards shipped with an uninitialized EEPROM and no write +protect pull-up resistor in place. Later units of all 4gb and 8gb models +sharing the same serial number in EEPROM data will have this problem that the +network mac addresses are alike between different models and this may be +corrected by defeating the write protect resistor to write new values. As an +alternative to this, it may be worked around by overriding the mac addresses +via U-Boot environment variables. + +It is required for any unit having uninitialized EEPROM and recommended for +all later Star64 4gb model units (not properly serialized) to have decided on a +new 6-byte serial number. This serial number should be high enough to +avoid collision with other JH7110 boards and low enough not to overflow i.e. +between ``cafe00`` and ``f00d00``. + +Update EEPROM values +^^^^^^^^^^^^^^^^^^^^ + +1.
