Jetson Power GUI

Robotics & Edge Computing Jetson & Embedded Systems Jetson Orin Nano

Orin NX
We created a power mode of 25W. with EMC max freq 3199000000 (EMC MAX FREQ 0)

upon power up we execute the command jetson_clocks --show.
the EMC current freq shows 665600000 , power GUI also shows 665600000. refer to first image.

then we execute jetson_clocks
the EMC current freq shows 3199000000, however power GUI shows 2133Mhz.
refer to second image

Can someone please explain the difference between jetson clocks and power GUI

@Vera Jiang can you redirect this to the appropriate forum? This is not Sanitizer-related. Thanks!

I see it already been redirected to “Jetson Nano”

Awesome thanks!

Hi zilkhanir1,

Are you using the devkit or custom board for Jetson Nano?
What’s your Jetpack version in use?

They should be the same.
The one showed in jetson clock is getten from bpmp node.
The one showed on Jetson Power GUI is read from emc path.

Could you also share your nvpmodel configuration in use for further check?

Using jetson nano devkit with jetson orin nx module

5.2.1

By the way i forgot to mention that some time the gui does show the correct frequency. But we dont know when.

FORMAT:

< PARAM TYPE=PARAM_TYPE NAME=PARAM_NAME >

ARG1_NAME ARG1_PATH_VAL

ARG2_NAME ARG2_PATH_VAL

…

This starts a section of PARAM definitions, in which each line

has the syntax below:

ARG_NAME ARG_PATH_VAL

ARG_NAME is a macro name for argument value ARG_PATH_VAL.

PARAM_TYPE can be FILE, or CLOCK.

< POWER_MODEL ID=id_num NAME=mode_name >

PARAM1_NAME ARG11_NAME ARG11_VAL

PARAM1_NAME ARG12_NAME ARG12_VAL

PARAM2_NAME ARG21_NAME ARG21_VAL

…

This starts a section of POWER_MODEL configurations, followed by

lines with parameter settings as the format below:

PARAM_NAME ARG_NAME ARG_VAL

PARAM_NAME and ARG_NAME are defined in PARAM definition sections.

ARG_VAL is an integer for PARAM_TYPE of CLOCK, and -1 is taken

as INT_MAX. ARG_VAL is a string for PARAM_TYPE of FILE.

This file must contain at least one POWER_MODEL section.

< PM_CONFIG DEFAULT=default_mode >

This is a mandatory section to specify one of the defined power

model as the default.

Are you using Orin Nano devkit board or Jetson Nano devkit board for Orin NX module…?

Is that a typo for Jetpack version?
We have only Jetpack 5.1.2 rather than 5.2.1.

May I know why you configure 0 for max EMC frequency?

9

Yes its a typo

I think it is orin nano (i will replay with a certain answer later)

I’ve moved your topic to correct category for Orin Nano.

Okay, you could enable the settings for EMC.

11

What do you mean by you could enable the settings for EMC?

12

Sorry, it was my mis-understanding.

Please just use the following command to check current EMC frequency.

$ sudo cat /sys/kernel/debug/bpmp/debug/clk/emc/rate
