Writing data in flash STM32F103

[SGasp.1]

Hi amazing community. 

I would like to write some data in the flash memory of the following mcu STM32F103

I know there are some dedicated pages for such purpose.

How can I guarantee or understand that the future code that i will develop and it will be saved for sure always

in the flash memory it won't overwrite the pages that i have used for saving the data?

Thanks a lot

Hello @SGasp.1,

You can manage it through the linker file, by reserving specific pages for your data ;)

Best Regards,

The MEMORY section describes base address and size of FLASH the Linker can use, shrink that by several KB to carve out space it can't allocate.
