Flashing the device
The ST Nucleo-F091 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 flash
and debug via GDB by simply typing
make debug
Supported Toolchains
For using the ST Nucleo-F091 board we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.
