    Hi, We do not use I2C EEPROM for eeprom emulation in our SDK but SPI flash. I2C eeprom is used for board detection now. So overwriting is not a good idea. Technically its possible to use I2C eeprom as ethercat eeprom. Please refer to evm documentation for eeprom layout and available free space

    Hi,

    As an example layout see below link, you can see that first 78 bytes are reserved for board detection etc and remaining area can be used by application
