Zephyr default configuration uses CAN_2 exclusively, as simultaneous use of CAN_1 and CAN_2 is not yet supported. Other hardware features are not yet supported on Zephyr porting. The default configuration can be found in the defconfig file: ``boards/arm/black_f407_generic/black_f407zg_pro_defconfig`` Pin Mapping =========== BLACK_F407ZG_PRO has 7 GPIO controllers. These controllers are responsible for pin muxing, input/output, pull-up, etc. Default Zephyr Peripheral Mapping: ---------------------------------- .. rst-class:: rst-columns - UART_1_TX : PB6 - UART_1_RX : PB7 - UART_2_TX : PA2 - UART_2_RX : PA3 - USER_PB : PA0 - LD3 : PD13 - LD4 : PD12 - LD5 : PD14 - LD6 : PD15 - USB DM : PA11 - USB DP : PA12 - CAN1_RX : PD0 - CAN1_TX : PD1 - CAN2_RX : PB12 - CAN2_TX : PB13 - SPI2 MISO : PC2 - SPI2 MOSI : PC3 - SPI2 SCK : PB10 System Clock ============ BLACK_F407ZG_PRO System Clock could be driven by internal or external oscillator, as well as main PLL clock. By default System clock is driven by PLL clock at 168MHz, driven by 8MHz high speed external clock. Serial Port =========== BLACK_F407ZG_PRO has up to 6 UARTs. The Zephyr console output is assigned to UART2. Default settings are 115200 8N1. Please note that ST-Link Virtual Com Port is not wired to chip serial port. In order to enable console output you should use a serial cable and connect it to UART2 pins (PA2/PA3). Programming and Debugging ************************* Applications for the ``black_f407zg_pro`` board configuration can be built and flashed in the usual way (see :ref:`build_an_application` and :ref:`application_run` for more details). Flashing ======== BLACK_F407ZG_PRO board includes an ST-LINK/V2 embedded debug tool interface. This interface is supported by the openocd version included in Zephyr SDK. Flashing an application to BLACK_F407ZG_PRO ------------------------------------------- Here is an example for the :zephyr:code-sample:`blinky` application. Run a serial host program to connect with your board: .. code-block:: console $ minicom -D /dev/ttyACM0 Build and flash the application: .. zephyr-app-commands:: :zephyr-app: samples/basic/blinky :board: black_f407zg_pro :goals: build flash You should see user led "LD1" blinking. Debugging ========= You can debug an application in the usual way. Here is an example for the :ref:`hello_world` application. .. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: black_f407zg_pro :maybe-skip-config: :goals: debug .. _STM32F407ZG on www.st.com: https://www.st.com/en/microcontrollers-microprocessors/stm32f407zg.html
