How to emulate EEPROM on K60(MK20DX512)

FirmFruits — Mon, 26 Jul 2021 23:51:27 GMT

Hi,

I am working on EEPROM creation using NVM of MK20DX512 on MCUXpresso IDE.

I looked at a few Application Notes(AN4282, AN4903, AN5338), but it seems that there was no information about MK20DX256, and it is difficult to understand the contents because it is written too complexly.

Q1. Is it possible to create eeprom emulation on MK20DX512?

Q2. If so, is there an example source code? What documentation can I refer to to get the example source code?

Hi,

You can refer the other sdk that has eeprom like frdm-ke15z.

Have a great day,

Thank you for reply.

As you replied, I took a look at the ke15z sdk.

There really is a FlexNVM eeprom emulation example. I have checked that it is implemented using the FSL FlexNVM driver.
But as you know, there is no FlexNVM driver in MK20DX256 SDK.

Should I implement not only application but also the driver for MK20DX256 myself / and just refer the KE15Z SDK?

Hi,

Yes. You should port the driver for the mk20. Copy the fsl_ftfx_xxx file into your project. And try to run it.

Some article for you to refer.

Have a great day,
