Hello all,

In our application, we want to do a back up of somes variables and put them in 1 page of the flash memory, we try to use it like an eeprom.

The question is : how can i reserve 1 page in flash memory to be sure that they won't be ecrased when we programm the micro or when there is no power?

Thx :p

Hi,tran:

I think you shoud employ IAP in your application.

Use the first 4KB of FLASH to store a IAP bootloader.

Then update your Application Code page by page, and not affect unused pages(these pages then can used for data store).

You may try the FreeIAP in mcuisp.exe, a STM32 ISP program write by me.
