EEPROM size on TX1 sensor board


The OV5693 sensor board comes with TX1 has an EEPROM (256 bytes) on it.
I study the OV5693 driver (drivers/media/i2c/ov5693) and find that this driver write/read 1024 bytes to/from EEPROM. I have 2 questions:

  1. What is the purpose of this EEPROM ? Is there any document to explain the data format in this EEPROM ?

  2. Why does the sensor driver use more EEPROM space than that available in sensor board ?


The EEPROM is for the image quality tuning purpose only you can just skip it.
