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, as well as the STM32L4 20ultra-low-power series. The STM32F4 series is pin-to-pin compatible with STM32F2 series. 21The following machines are based on this ARM Cortex-M4F chip : 22 23- ``netduinoplus2`` Netduino Plus 2 board with STM32F405RGT6 microcontroller 24- ``olimex-stm32-h405`` Olimex STM32 H405 board with STM32F405RGT6 microcontroller 25- ``b-l475e-iot01a`` :doc:`B-L475E-IOT01A IoT Node </system/arm/b-l475e-iot01a>` board with STM32L475VG microcontroller 26 27There are many other STM32 series that are currently not supported by QEMU. 28 29Supported devices 30----------------- 31 32 * ARM Cortex-M3, Cortex M4F 33 * Analog to Digital Converter (ADC) 34 * EXTI interrupt 35 * Serial ports (USART) 36 * SPI controller 37 * System configuration (SYSCFG) 38 * Timer controller (TIMER) 39 40Missing devices 41--------------- 42 43 * Camera interface (DCMI) 44 * Controller Area Network (CAN) 45 * Cycle Redundancy Check (CRC) calculation unit 46 * Digital to Analog Converter (DAC) 47 * DMA controller 48 * Ethernet controller 49 * Flash Interface Unit 50 * GPIO controller 51 * I2C controller 52 * Inter-Integrated Sound (I2S) controller 53 * Power supply configuration (PWR) 54 * Random Number Generator (RNG) 55 * Real-Time Clock (RTC) controller 56 * Reset and Clock Controller (RCC) 57 * Secure Digital Input/Output (SDIO) interface 58 * USB OTG 59 * Watchdog controller (IWDG, WWDG) 60 61Boot options 62------------ 63 64The STM32 machines can be started using the ``-kernel`` option to load a 65firmware.
