Hi,

I am working on STM32G071RB Nucleo Board and In one of project , I am using same MCU.

In that Project , I don't want to use external I2C or SPI memory for saving the data (logs).

1) How do I can access Flash as EEPROM ?

2) Will this possible with STM32Cube MX ?

3) How the EEPROM Locations (Say 100 Bytes) are separated from Flash Memory Content (Actual Program) ?

Thanks in Advance

Check the AN4894 Application note "EEPROM emulation techniques and software for STM32 microcontrollers" and the X-CUBE-EEPROM library.

Hi @KnarfB​ ,

Thanks for Update. I have already seen that Application Note and  X-CUBE-EEPROM library.

I am trying to use that (add) Library in my existing project (EEPROM_Emul Folder)

But facing below issue eeprom_emul.h .

../Core/Src/main.c:27:10: fatal error: G:\STM32G0 Cube\Dec 2021\Single Timer - 2\BlinkingG0\EEPROM_Emul\core\eeprom_emul.h: No such file or directory
 
 #include "G:\STM32G0 Cube\Dec 2021\Single Timer - 2\BlinkingG0\EEPROM_Emul\core\eeprom_emul.h"

Please check attach code using that library.

Thanks for your concern..

The compiler says it can't find that file, does that file exist on the drive?

Usually relative directories are used for include files.

Hi TDK,

Thanks for update..

1) Have to check attached project.. ?

2) eeprom_emul.h is already present inside the EEPROM_Emul Folder ?

-Usually relative directories are used for include files.

Can you help to compile this attached project..?

Spaces in the path. "G:\STM32G0 Cube\Dec 2021\Single Timer - 2\....."

This can cause all kinds of nasty things.
