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 |
44.67 |
203.25 |
Idle |
194.21 |
883.66 |
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

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
ð { 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"; };
