Genio 1200-EVK

Overview

Genio 1200-EVK board is an evaluation kit of MediaTek. For detailed hardware specifications, please refer to Genio 1200-EVK. We will use the G1200-EVK with multiple modules as a platform to measure the power consumption in suspend and idle mode. The provided low power data may vary due to hardware differences and has a tolerance of 10% error. These data are for reference only.

Measurement settings

  • Software Version : v23.2

  • Operating Voltage : 4.55 V

  • The LEDs on board need to be removed before measurement.

  • Connect power supply to EVK and start measurement.

Power Consumption of G1200-EVK

The following is the power consumption data of Suspend and Idle, and we will provide the measurement SOP.

Suspend

  • Step 1 : Power on DUT

  • Step 2 : Wait for the system to initialize, about 1-2 minutes

  • Step 3 : Turn off CAN device

    ifconfig can0 down

  • Step 4 : Requires the system to enter suspend mode

    echo mem > /sys/power/state

  • Step 5 : The console cannot input commands, which means it enters suspend

  • Step 6 : Wait for 1 minute and start measuring

Idle

  • Step 1 : Power on DUT

  • Step 2 : Wait for the system to initialize, about 1-2 minutes

  • Step 3 : Turn off CAN device

    ifconfig can0 down

  • Step 4 : turn off some extra services

    cd /etc/netopeer2 ; sh netopeer2-server stop
systemctl stop NetworkManager.service
echo off > /sys/class/drm/card0-DSI-1/status

  • Step 5 : Wait for 1 minute and start measuring

Power Consumption of Components

Genio 1200-EVK contains a number of additional components, the following is the power consumption of each module under suspend mode.

Disable Component

  • MT7921 :

    If you do not need to use WIFI and Bluetooth, you can remove the MT7921 module to reduce power consumption

  • Display panel :

    If you do not need a screen display, you can remove the screen cable to reduce power consumption

  • Ethernet :

    If you do not need to use Ethernet, you can set status = “disabled” to eth node in genio-700-evk.dts to reduce power consumption

    &eth {
    status = "disabled";
}

  • USB Hub :

    If you do not need this module, you can remove the hardware in your platform

  • SCP :

    If you do not need this module, you can set status = “disabled” to scp node in genio-700-evk.dts to reduce power consumption

    &scp {
    status = "disabled";
};
