How do I set the BOR option bytes for an STM32F4? There is an example STM32F10xOPT.s in Blinky that has a Keil wizard with it. I cannot find any other ...OPT.s in my installation. Is there somewhere I can download a STM32F4xOPT.s and if I include it in the project will the wizard include BOR settings?

Configuring STM32F Option bytes (including BOR) requires programming certain bytes at specific addresses.
This can be achieved by:
1. Adding an appropriate configuration file to the project - right-click on a Group in uVision Project window and chose “Add New Item to Group …” - click on “User Code Template” - expand “Device” - select “Flash Option Bytes” - click “Add”
2. Configure the desired features in the file “STM32F4xxx_OPT.s” (Configuration Wizard can be used)
3. Build the project
4. Add the Flash programming algorithm for the Option bytes Project – Options for Target … - Utilities: click on Settings Add Algorithm STM324xxxx Flash Options
5. Flash the image
The mentioned Blinky example – target STM32f407 OPT is configured in this way and can be used as a reference.
