Configuration File Format
The eeprom devices are listed under the corresponding i2c bus number. Whenever you add a new EEPROM
to the bus number, the number of devices in each bus number updates. Each
eeprom field is separated by the
‘|’ character. The order of the fields are:
1 Name of the EEPROM. Provides the same name at the eeprom option in the eepromtool.
2 The bus to which the EEPROM connects.
3 The i2c path of the EEPROM. If a MUX present, the MUX address, offset, and value are separated by
colons.
4 The i2c address of the EEPROM.
5 Specifies if the device is a 16–bit address access.
6 Byte count to read or write.
7 Specifies the format of the data in the eeprom as tlv or flat.
8 Write protect register, if applicable.
9 Write protect register mask.
10 Bus Return to Normal - Any bus configurations needed to return the bus to a valid setting. If you need
any MUX settings, they are listed as address : register : mask : value. Each successive MUX
setting is separated with a :,:.
