Flashing the device

The ST Nucleo-F446RE 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-f446re flash

and debug via GDB by simply typing

make BOARD=nucleo-f446re debug

Supported Toolchains

For using the ST Nucleo-F446RE board we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.

Caveats

SPI pin and LED0 share lines so LED0 is not initialized be default. If you want to use it, you need to add CFLAGS += -DAUTO_INIT_LED0 to your Makefile and disable conflicting radio modules.
