Jetson Nano reduce power consumption

Hi,

currently i am developing a Jetson Nano carrier board with focus on minimal power consumption cause we are powering the board with battery.

Already disabled some modules like HDMI/DSI some modules in device tree but power consumption doesnt really reduce.

At the moment it requires about 700 - 1200mW while idle.

Is it possible to further reduce it? Can i power gate some parts of the SOC?

Dont need

  • Ethernet
  • PCIe
  • HDMI
  • DSI

Best regards

Malte

Sorry for the late response, is this still an issue to support? Thanks

Hi,

Please also disable all of those interfaces from the device tree.

Thanks for your response.

Disabling the modules in device tree also disables their power supplies?

Til now I disable hdmi by

&{/host1x/dc@54200000} {
status = “disabled”;
};

&{/host1x/dc@54240000} {
status = “disabled”;
};

&{/host1x/dsi} {
status = “disabled”;
};

&{/host1x/sor} {
status = “disabled”;
};

&{/host1x/sor/hdmi-display} {
status = “disabled”;
};

&{/host1x/sor/dp-display} {
status = “disabled”;
};

&{/host1x/sor1} {
status = “disabled”;
};

How can I disable the ethernet module for example?

Best reagrds

@laama Were you able to reduce the power consumption by disabling the interfaces?
