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- ``olimex-stm32-h405`` Olimex STM32 H405 board with STM32F405RGT6 microcontroller 24 25There are many other STM32 series that are currently not supported by QEMU. 26 27Supported devices 28----------------- 29 30 * ARM Cortex-M3, Cortex M4F 31 * Analog to Digital Converter (ADC) 32 * EXTI interrupt 33 * Serial ports (USART) 34 * SPI controller 35 * System configuration (SYSCFG) 36 * Timer controller (TIMER) 37 38Missing devices 39--------------- 40 41 * Camera interface (DCMI) 42 * Controller Area Network (CAN) 43 * Cycle Redundancy Check (CRC) calculation unit 44 * Digital to Analog Converter (DAC) 45 * DMA controller 46 * Ethernet controller 47 * Flash Interface Unit 48 * GPIO controller 49 * I2C controller 50 * Inter-Integrated Sound (I2S) controller 51 * Power supply configuration (PWR) 52 * Random Number Generator (RNG) 53 * Real-Time Clock (RTC) controller 54 * Reset and Clock Controller (RCC) 55 * Secure Digital Input/Output (SDIO) interface 56 * USB OTG 57 * Watchdog controller (IWDG, WWDG) 58 59Boot options 60------------ 61 62The STM32 machines can be started using the ``-kernel`` option to load a 63firmware.
