How can I change the Orin NX's power mode?

highsoul1227 · March 3, 2024, 4:40pm

I changed my Orin NX’s power mode to 25W(ID:2), and I tried to change again to MAXN mode, but it didn’t work.

And this is the error code

v$ sudo nvpmodel -m 0
NVPM ERROR: Error opening /sys/devices/system/cpu/cpu6/online: 2
NVPM ERROR: failed to write PARAM CPU_ONLINE: ARG CORE_6: PATH: /sys/devices/system/cpu/cpu6/online VAL: 1

Hi highsoul1227,

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

Could you run MAXN mode before?

You should use sudo for this command.

$ sudo nvpmodel -q

Please share the /etc/nvpmodel.conf from your board.

I used MAXN mode before.
And I tried to use command with sudo of course.
Below is the $cat /etc/nvpmodel.conf

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

Please also share the result of the following command on your board.

$ cat /etc/nv_boot_control.conf

Umm… I bought Seeed studio’s reComputer J4011-Edge model(Jetson Orin NX 8GB)

It seems you are using custom carrier board(from Seeed Studio) with Orin NX 8G module (SKU 0001).

It has only 6 cores CPU (cpu0 to cpu5) so that it reporting the following error.

NVPM ERROR: Error opening /sys/devices/system/cpu/cpu6/online: 2

Could you replace /etc/nvpmodel.conf from your board with the following configuration file?
nvpmodel_p3767_0001.conf (7.6 KB)
and run sudo nvpmodel -m 0 again to apply MAXN mode.
