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:
CAN RX/TX/STBY: PD0/PD1/PD2
I2C1 SCL/SDA : PB8/PB9 (Arduino I2C)
LD1 : PA5
LD2 : PC9
SPI1 NSS/SCK/MISO/MOSI : PA15/PA5/PA6/PA7 (Arduino SPI)

Programming and Debugging
The nucleo_c092rc board supports the runners and associated west commands listed below.
| flash | debug | rtt | attach | debugserver | |
|---|---|---|---|---|---|
| jlink | ✅ | ✅ (default) | ✅ | ✅ | ✅ |
| stm32cubeprogrammer | ✅ (default) |
Nucleo C092RC board includes an ST-LINK/V2-1 embedded debug tool interface.
Applications for the nucleo_c092rc board 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 [4] runner, so its installation is required.
Alternatively, an external JLink (Software and Documentation Package Version >= v8.12e)
can also be used to flash the board using the --runner option:
$ west flash --runner jlink
Flashing an application to Nucleo C092RC
Here is an example for the Blinky application.
# From the root of the zephyr repository
west build -b nucleo_c092rc samples/basic/blinky
west flash
You will see the LED blinking every second.
