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
J-Link OB Firmware
Like many other STM32 evaluation boards, the Nucleo F722ZE’s on-board ST-LINK
debug interface may be flashed with SEGGER J-Link OB firmware. This
firmware turns the ST-LINK into a J-Link probe. If the on-board debugger has
been re-flashed with J-Link OB firmware, simply append --runner jlink to
all flashing/debugging commands.
