Hi ,
I’m using Orin NX 16GB and Jetpack on custom board.
Instead of GUI, I want to set power mode to 10W in terminal.
is it possible?
I’m wondering if the above settings still apply or reset after reboot.
Also, I would like to know how to set it up permanently if it is reset.
Run
sudo nvpmodel -m <# of power mode>
You can check /etc/nvpmodel.conf for available power modes.
YES.
Thank you for your quick response.
I have more questions.
Does power mode mean MAX power?
If it means MAX power, does it not exceed this value at boot time?
Or from when does the power mode apply after the board starts booting?
Thanks.
I mean you should check /etc/nvpmodel.conf for what power mode you want to set.
MAXN is just one of them.
On the board I have, POWER MODE has a 10w option, but official docs don’t have a 10w option.
What documents should I refer to?
Check the document that corresponds to the L4T version running on your device:
https://docs.nvidia.com/jetson/archives/r35.5.0/DeveloperGuide/SD/PlatformPowerAndPerformance/JetsonOrinNanoSeriesJetsonOrinNxSeriesAndJetsonAgxOrinSeries.html#supported-modes-and-power-efficiency
10W is available on newer versions.
Thanks.
If I set 10W, does max power not exceed 10w no matter what app I run?
As I asked above, I wonder when the power mode is applied after the power is applied.
It’s only an approximation.
I don’t think it’s guaranteed that the total power comsumption will always not exceed the limit.
If it doesn’t involve enabling/disabling addtional CPU cores, then it takes effect immediately;
it it does, reboot is required for the new power mode to apply.
I’m not sure what this part means.
If I don’t touch the core settings other than the power mode during the boot process, does that mean that the power mode I pre-set will be applied immediately?
For example, this is the power mode config on my AGX Orin:
# MAXN is the NONE power model to release all constraints

CPU_ONLINE CORE_X 0 means this CPU core is disabled and is not visible to the system.
Like if you are now at mode 0 (MAXN), where all 12 cores are enabled, and you want to switch to mode 2 (30W), in which core 8, 9, 10, 11 are disabled, then reboot is required; but if you switch to mode 3 (50W), there is no change in enabling/disabling any CPU cores, so it takes effect immediately and you don’t need to reboot the device.
Oh! I understand what you mean.
However, I am experiencing one problem and need debugging.
Despite setting it to 10W and rebooting it multiple times, the situation continues to soar to 16-19w during the boot process.
This is why I kept asking when the power mode was applied during the booting process.
I’ll test this part a little bit more.
Thank you.
CPU cores are only disabled after it boots into the Linux kernel, and they are all enabled in earlier bootloader stages.
It is expected that the device will consume more power during boot as it performs self hardware check, so every hardware component will be triggered, hence higher power comsumption. The same goes for an x86 PC.
