1STMicroelectronics STM32 boards (``netduino2``, ``netduinoplus2``, ``stm32vldiscovery``) 2======================================================================================== 3 4The `STM32`_ chips are a family of 32-bit ARM-based microcontroller by 5STMicroelectronics. 6 7.. _STM32: https://www.st.com/en/microcontrollers-microprocessors/stm32-32-bit-arm-cortex-mcus.html 8 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 23 24There are many other STM32 series that are currently not supported by QEMU. 25 26Supported devices 27----------------- 28 29 * ARM Cortex-M3, Cortex M4F 30 * Analog to Digital Converter (ADC) 31 * EXTI interrupt 32 * Serial ports (USART) 33 * SPI controller 34 * System configuration (SYSCFG) 35 * Timer controller (TIMER) 36 37Missing devices 38--------------- 39 40 * Camera interface (DCMI) 41 * Controller Area Network (CAN) 42 * Cycle Redundancy Check (CRC) calculation unit 43 * Digital to Analog Converter (DAC) 44 * DMA controller 45 * Ethernet controller 46 * Flash Interface Unit 47 * GPIO controller 48 * I2C controller 49 * Inter-Integrated Sound (I2S) controller 50 * Power supply configuration (PWR) 51 * Random Number Generator (RNG) 52 * Real-Time Clock (RTC) controller 53 * Reset and Clock Controller (RCC) 54 * Secure Digital Input/Output (SDIO) interface 55 * USB OTG 56 * Watchdog controller (IWDG, WWDG) 57 58Boot options 59------------ 60 61The STM32 machines can be started using the ``-kernel`` option to load a 62firmware.
