Pin Mapping
STM32F072-EVAL Discovery kit has 6 GPIO controllers. These controllers are responsible for pin muxing, input/output, pull-up, etc.
For more details please refer to STM32F072-EVAL board User Manual.
Default Zephyr Peripheral Mapping:
UART_2_TX : PD5
UART_2_RX : PD6
TAMPER_PB : PC13
JOYSTICK_RIGHT_PB : PE3
JOYSTICK_LEFT_PB : PF2
JOYSTICK_UP_PB : PF9

System Clock
STM32F072-EVAL System Clock could be driven by an internal or external oscillator, as well as the main PLL clock. By default the System clock is driven by the PLL clock at 48MHz, driven by an 8MHz high speed internal clock.
Serial Port
STM32F072-EVAL Discovery kit has up to 4 UARTs. The Zephyr console output is assigned to UART2. Default settings are 115200 8N1.
Programming and Debugging
STM32F072-EVAL Discovery kit includes an ST-LINK/V2 embedded debug tool interface.
Applications for the stm32f072_eval board configuration can be built and
flashed in the usual way (see Building an Application and
Run an Application for more details).
Flashing
The board is configured to be flashed using west STM32CubeProgrammer runner, so its installation is required.
Alternatively, OpenOCD or JLink can also be used to flash the board using
the --runner (or -r) option:
$ west flash --runner openocd
$ west flash --runner jlink
Flashing an application to STM32F072-EVAL
Here is an example for the Blinky application.
# From the root of the zephyr repository
west build -b stm32f072_eval samples/basic/blinky
west flash
You will see the LED blinking every second.
Debugging
You can debug an application in the usual way. Here is an example for the Blinky application.
# From the root of the zephyr repository
west build -b stm32f072_eval samples/basic/blinky
west debug
