Internal file system KL25Z

Good morning! I'm designing an electronic lock using KL25Z, I need to store the unlock code. Can I use a text file (.txt) stored on the internal file system using the same methods used for the LPC1768?

No, the KL25Z does not support a internal file system, because there is no external Flash. There is a socket U5 on the board for a AT45DB161 flash, but the firmware does not support this today ...

You can add a small SPI or I2C EEProm to store the code. It is also possible to write the code into a not used KL25Z flash page, but I think there is no library for that at the moment.

thank you! but if you want to change the unlock code as I do not lose after power off the system?
