| STMicroelectronics STM32 boards (``netduino2``, ``netduinoplus2``, ``stm32vldiscovery``) |
| ======================================================================================== |
| |
| The `STM32`_ chips are a family of 32-bit ARM-based microcontroller by |
| STMicroelectronics. |

| |
| The STM32F1 series is based on ARM Cortex-M3 core. The following machines are |
| based on this chip : |
| |
| - ``stm32vldiscovery`` STM32VLDISCOVERY board with STM32F100RBT6 microcontroller |
| |
| The STM32F2 series is based on ARM Cortex-M3 core. The following machines are |
| based on this chip : |
| |
| - ``netduino2`` Netduino 2 board with STM32F205RFT6 microcontroller |
| |
| The STM32F4 series is based on ARM Cortex-M4F core, as well as the STM32L4 |
| ultra-low-power series. The STM32F4 series is pin-to-pin compatible with STM32F2 series. |
| The following machines are based on this ARM Cortex-M4F chip : |
| |
| - ``netduinoplus2`` Netduino Plus 2 board with STM32F405RGT6 microcontroller |
| - ``olimex-stm32-h405`` Olimex STM32 H405 board with STM32F405RGT6 microcontroller |
| - ``b-l475e-iot01a`` :doc:`B-L475E-IOT01A IoT Node </system/arm/b-l475e-iot01a>` board with STM32L475VG microcontroller |
| |
| There are many other STM32 series that are currently not supported by QEMU. |

| Boot options |
| ------------ |
| |
| The STM32 machines can be started using the ``-kernel`` option to load a |
| firmware. Example: |
| |
| .. code-block:: bash |
| |
| $ qemu-system-arm -M stm32vldiscovery -kernel firmware.bin |
