STM32F401RCT6 EEPROM Emulation

omeraydin · ‎2023-09-11

Hi,

I need to use EEPROM Emulation for my project's needs. I'm using STM32F401RCT6. I tried to use EEPROM emulation in STM32F40x/STM32F41x microcontrollers (AN3969) but after several tries, I only got errors as screenshot at below:

Any help would be appreciated, thanks.

Hello @omeraydin

I suggest you to use on of those exemples :

X-CUBE-EEPROM1 exemples (3 exemples devlopped by ST)
exemple devlopped by an independent developer.

Best regards.

Hello @omeraydin,

Perhaps you are using different implementation of xx_hal_flash.h file maybe for a different product. You need to pay attention to the driver being used.

please check the library used for eeprom and your function implemention.

may be your "NbPages" or "PageAddress" should be "NbSectors"/"Sectors".

Do check your flashstruct
