STM32 PM STOP3 mode

Overview

This sample is a minimum application to demonstrate basic power management behavior in a basic blinking LED set up and STM32U5 STOP3 low power mode.

Requirements

At the moment, only nucleo_u575zi_q board is supported. The board shall have an RTC to use it during the standby mode as a replacement for LPTIM (which is disabled).

Building and Running

Build and flash examples as follows:

west build -b nucleo_u575zi_q samples/boards/stm32/power_mgmt/stop3
west flash

After flashing, the LED starts to blink.

PM configurations

By default, CONFIG_PM_DEVICE and CONFIG_PM_DEVICE_RUNTIME are enabled.
