| Overview |
| ******** |
| |
| The STM32 Nucleo-144 boards offer combinations of performance and power that |
| provide an affordable and flexible way for users to build prototypes and try |
| out new concepts. For compatible boards, the SMPS significantly reduces power |
| consumption in Run mode. |
| |
| The Arduino-compatible ST Zio connector expands functionality of the Nucleo |
| open development platform, with a wide choice of specialized Arduino* Uno V3 |
| shields. |
| |
| The STM32 Nucleo-144 board does not require any separate probe as it integrates |
| the ST-LINK/V2-1 debugger/programmer. |
| |
| The STM32 Nucleo-144 board comes with the STM32 comprehensive free software |
| libraries and examples available with the STM32Cube MCU Package. |
| |

| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: nucleo_f746zg |
| :goals: build flash |
| |
| You should see the following message on the console: |
| |
| .. code-block:: console |
| |
| $ Hello World! nucleo_f746zg |
| |
| Debugging |
| ========= |
| |
| You can debug an application in the usual way. Here is an example for the |
