System Clock

By default, the system clock is driven by the external clock supplied by the ST-LINK interface. Nucleo F722ZE system clock can be driven by internal or external sources.

Serial Port

Zephyr console is assigned to UART3 (ST-Link Virtual COM Port) by default, using 115200 8N1.

Programming and Debugging

The nucleo_f722ze can be flashed and debugged in the typical manner. The Nucleo F722ZE board includes an ST-LINK V2-1 debugger, which can be used with the OpenOCD version provided with the Zephyr SDK. Refer to Building an Application and Run an Application for detailed instructions.

Flashing

Build the Hello World application and flash it using the on-board ST-LINK interface:

# From the root of the zephyr repository
west build -b nucleo_f722ze samples/hello_world
west flash

Debugging

# From the root of the zephyr repository
west build -b nucleo_f722ze samples/hello_world
west debug
