@ -20,6 +20,7 @@ The STM32F4 series is based on ARM Cortex-M4F core. This series is pin-to-pin
compatible with STM32F2 series. The following machines are based on this chip :
- ``netduinoplus2`` Netduino Plus 2 board with STM32F405RGT6 microcontroller
- ``olimex-stm32-h405`` Olimex STM32 H405 board with STM32F405RGT6 microcontroller
There are many other STM32 series that are currently not supported by QEMU.
