ST STM32373C Evaluation
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 [1].

Other hardware features are not yet supported in this Zephyr port.
The default configuration can be found in the defconfig file boards/arm/stm32373c_eval/stm32373c_eval_defconfig
Connections and IOs
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.

Default Zephyr Peripheral Mapping:
UART_2_TX : PD5
UART_2_RX : PD6
USER_PB : PA2
LED2 : PC1
Programming and Debugging
Applications for the stm32373c_eval board configuration can be built and
flashed in the usual way (see Building an Application and
Run an Application for more details).
Flashing
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.
Flashing an application to STM32373C-EVAL
Here is an example for the Blinky application.
# From the root of the zephyr repository
west build -b stm32373c_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 stm32373c_eval samples/basic/blinky
west debug
