Introduction

Introduction
Power consumption is highly dependent on the individual user’s application; however, this document
focuses on providing several AM574x application-usage case scenarios and the environment settings that
were used to perform such power measurements. This collection of real power measurements was
measured on internal AM574x boards with on-board power measurement device (TI INA226).
See the AM5748 product page for additional details about the AM574x processor.
1.1
Power Measurement Setup
The following sections detail power measurements taken on a AM574x platform for typical use case
applications. These measurements have been performed on an internal test evaluation reference system
and not on the AM574x evaluation module (TMDXEVM5748). A heatsink (31-mm x 31-mm x 19.5-mm,
#ATS-54310R-C1-R0) is installed.
NOTE: The software being used is a TI Processor SDK Linux for AM57x Sitara Processors with
default configurations. Be aware power consumption varies across devices and is affected by
temperature and voltage. All of the readings shown here are taken at room temperature
(25°C).
The most of power supply groups has been measured using TI INA226. The test set-up details are as
follows:
• SD card with Processor SDK 05.02.00 Linux
• Powertool
• Option 1: BeagleBone Black and Windows® computer
• Option 2: FT2232H Mini Module and Linux™ computer
Powertool is used to communicate with the I2C bus containing INA226 devices onboard the evaluation
board. It comes with a config file that works with AM574x. The README of Powertool contains the
information needed to proceed with option 1 or option 2. In the case of option 2, the powertool is compiled
on the Linux PC and powertool uses the FTDI Mini Module as a USB-to-I2C converter. With option 1, the
powertool is compiled on the BeagleBone Black and it uses the BeagleBone I2C1 or I2C2 bus for power
measurements. With the powertool compiled, run it with the below command:
$ ./ptool -c configs/am574x.conf -e

High-Level Summary
The following tables contain a high-level summary of the total device power (measured in milliwatts) for
each application use case and configuration.
2.1
OS Idle
In this measurement, no application is running on Linux and no display connected. The Linux CPUFreq
driver automatically adjusts MPU OPP to NOM when idle. In this case, CPUFreq is manually set to each
MPU OPP.
