9The STM32F1 series is based on ARM Cortex-M3 core. The following machines are
10based on this chip :
11
12- ``stm32vldiscovery``  STM32VLDISCOVERY board with STM32F100RBT6 microcontroller
13
14The STM32F2 series is based on ARM Cortex-M3 core. The following machines are
15based on this chip :
16
17- ``netduino2``         Netduino 2 board with STM32F205RFT6 microcontroller
18
19The STM32F4 series is based on ARM Cortex-M4F core. This series is pin-to-pin
20compatible with STM32F2 series. The following machines are based on this chip :
21
22- ``netduinoplus2``     Netduino Plus 2 board with STM32F405RGT6 microcontroller

61The STM32 machines can be started using the ``-kernel`` option to load a
62firmware. Example:
63
64.. code-block:: bash
65
66  $ qemu-system-arm -M stm32vldiscovery -kernel firmware.bin
