The STM32 F4 discovery is an evaluation board for the ARM Cortex-M4 STM32F407VGT6 MCU.

This board has an integrated STLink compatible interface which can be configured to allow the programming of either the board itself or to program an external device.

As with all STM evaluation boards there is lengthy list of restrictions in place regarding what you can and can't do with an evaluation board. See this document.

CN3 is used to configure either internal or external programming.

Install OpenCM3.

Install STLink programmer.

Enter the OpenCM3 fancy blink example's sub-directory and program the chip.
