Flashing the device¶
The ST Nucleo-F070 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
1 | make BOARD=nucleo-f070 flash
|
1 | make BOARD=nucleo-f070 debug
|
Supported Toolchains¶
For using the ST Nucleo-F070 board we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.
