How to write EEPROM inside STM32F746G-DISCO board ?

Hi.

I am developing a project using the STM32F746G-DISCO board.

During development, there are cases where EEPROM needs to be used. Is the STM32F746G-DISCO usable like EEPROM by using internal flash?

I tried using the STM32F746G-DISCO default sample source in STM32CUBE-IDE, but it doesn't work.

STM32L1 to L4 have experience using internal flash as an EEPROM.

If possible, I would appreciate it if you could tell me a simple way.

Easiest way: Attach external EEPROM or use battery/goldcap backup and the backup registers. Or get you code right.

To add an external EEPROM, a user PCB made based on the STM32F746G-DISCO board is completed, so it cannot be added.

Is there a way to use a part of the internal flash as a data storage method for EEPROM?

Can I use the photo file downloaded from STM32Cube_FW_F7_V1.16.0?

I tried using both of the provided folder files, but it didn't work out, so I'd like to ask you again.

Can't I use the internal flash like an eeprom?

I can use it, but am I not able to?
