ADI Power Modes

Browse source code on GitHub

Overview

The ADI PM sample exercises the power modes of a given SoC for demonstration purposes and power measurements.

The prj.conf shows the required Kconfig for enabling power management and the devicetree overlay file shows how to configure the RAM retention per memory bank.

Requirements

The board should support power management and have a counter device that can be used as a system timer companion.

Building and Running

Build and flash ADI power modes as follows:

west build -b max32657evkit/max32657 samples/boards/adi/power_mgmt/power_modes
west flash

After flashing, the application repeatedly cycles through all power modes defined in the devicetree by sleeping at least the minimum residency time required for each mode.

Tips:

• When testing power modes or enabling PM on your device, it’s a good idea to enable CONFIG_BOOT_DELAY so your debugger doesn’t get locked out.
