Novena has a utility EEPROM that can be used for storing device-specific data. This is optional, and default values will be used if it is blank / not present.
All multi-byte integers are in native host order.
Structure
| Size | Default Value | Description | Result if no EEPROM present |
|---|---|---|---|
| 6 | 'Novena' | Unterminated EEPROM signature | The EEPROM contents will not be used |
| 1 | 1 | Version number of EEPROM structure | The EEPROM contents will not be used |
| 1 | 0xff | Supported peripherals | All peripherals are assumed present |
| 4 | 0 | Device serial number | No change |
| 6 | (Random) | Gigabit MAC address | Random MAC address is generated on each boot |
