K64 save data

edgarmosqueda — Tue, 07 Mar 2017 21:59:51 GMT

Hi everybody.

I'm working with a k64FN1M0, I'm traying to store data in the flex memory, when my program is running the following line:

while(!(FTFE_FCNFG & FTFE_FCNFG_EEERDY_MASK));

The program fall into an endless loop, I saw the FTFE_FCNFG register always is 0x06 and I can't change it, ´cause the register is only read.

Please, would you like to help me about it?.

Thanks.

Kind Regards.
Edgar Mosqueda.

Hi Edgar mosqueda,

This question is the same as the case, and I already reply you in the case.

Please note, K64FN1M0 chip don't have the flexNVM module, it just have the Pflash, it doesn't have the EEPROM function.
So, you need to store the data in the flash according address directly, just operate the flash, not the EEPROM.
K64FN1M0 don't have eeprom function.
K64FX512XX have the flexNVM and the eeprom function.

EEERDY bit for devices without FlexNVM is reserved.

Wish it helps you!

Have a great day,
Kerry
