Flashing the device

The ST Nucleo-F103 board includes an on-board ST-LINK V2 programmer. The easiest way to program the board is to use OpenOCD. Once you have installed OpenOCD (look here for installation instructions), you can flash the board simply by typing:

make BOARD=nucleo-f103 flash

and debug via GDB by simply typing

make BOARD=nucleo-f103 debug

Supported Toolchains

For using the ST Nucleo-F103 board we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.
