Reserving microcontroller Flash non-volatile memory

[JimEno]

I want to reserve a chunk of internal Flash memory in the micro-controller to store some user parameters. I want to develop a custom driver to manage the sector of Flash including erasing and re-writing the sector (there better be utility functions for Flash Sector erase and write). In the 'olden days' with a linker command file, I could do that easily. I can't seem to find that capability in the STMCube IDE with the file <project.ioc>. How do I do this?

The linker script will be a *.ld file that is created when you generate the code. You can modify the main FLASH section within the linker script to avoid writing to the reserved flash sector.
