Overview
The STM32373C-EVAL evaluation board is designed as a complete demonstration and development platform for STMicroelectronics ARM Cortex-M4 core-based STM32F373VCT6 microcontroller.
The full range of hardware features on the board can help the user evaluate all peripherals (USB FS, USART, audio DAC, microphone ADC, dot-matrix LCD, IrDA, LDR, MicroSD card, HDMI CEC, ECG, pressure sensor, CAN, IR transmitter and receiver, EEPROM, touch slider, temperature sensor, etc.) and develop their own applications.
Extension headers make it possible to easily connect a daughter board or wrapping board for a specific application.
More information about the board can be found at the STM32373C-EVAL website_.

STM32F373VCT6 reference manual_.. zephyr:board-supported-hw::
Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as input (with or without pull-up or pull-down), or as peripheral alternate function. Most of the GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current capable except for analog inputs.

Programming and Debugging
.. zephyr:board-supported-runners::
Applications for the stm32373c_eval board configuration can be built and
flashed in the usual way (see :ref:build_an_application and
:ref:application_run for more details).
STM32373C-EVAL board includes an ST-LINK/V2-1 embedded debug tool interface. At power-on, the board is in firmware-upgrade mode (also called DFU for "Device Firmware Upgrade"), allowing the firmware to be updated through the USB. This interface is supported by the openocd version included in Zephyr SDK.
Here is an example for the :zephyr:code-sample:blinky application.
.. zephyr-app-commands:: :zephyr-app: samples/basic/blinky :board: stm32373c_eval :goals: build flash
You will see the LED blinking every second.
You can debug an application in the usual way. Here is an example for the
:zephyr:code-sample:blinky application.
