   Hi @xiaotailang you are correct! Using EEPROM with MTD is slow if your EEPROM is I2C. The mount issue you are facing is because the auto-mount command expects that the MTD device be formatted as VFAT before using it. I have a 5 years old tutorial explaining how to use MTD with EEPROM: https://www.youtube.com/watch?v=qzjf2JtgYN0 but that version of NuttX is old.
   You could avoid using filesystem and write directly to the EEPROM device file, look at drivers/eeprom/README.txt this is a char device EEPROM driver. I used it in a project storing the packages data directly in the EEPROM. It is away faster.
