Flashing the device

The ST Nucleo-F411RE board includes an on-board ST-LINK V2-1 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

1
make BOARD=nucleo-f411 flash
and debug via GDB by simply typing 
1
make BOARD=nucleo-f411 debug

Supported Toolchains

For using the ST Nucleo-F411 board we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.
