To enable MaxN on Jetson Orin Nano, you’ll need to follow a series of steps. Before we dive into the solution, let’s break down the components involved:

1. Jetson Orin Nano: A carrier board for the Jetson Orin NX/Nano platform.
2. JetPack 6.2.1: A software development package for NVIDIA Jetson devices, which includes the Linux distribution, libraries, and tools for developing applications.
3. SDK Manager: A tool for downloading and installing JetPack on a Jetson device.
4. MaxN: A mode that needs to be enabled on the Jetson Orin Nano.

Now, let’s address the issue:

You’ve downloaded JetPack 6.2.1 using the SDK Manager and installed it on an SSD. You’ve also tried to enable MaxN by deleting the /etc/nvpmodel.conf file and rebooting the device. However, this didn’t work, and executing jtop shows that JetPack is not detected.

To resolve this issue, you can try the following:

1. Verify the installation: Ensure that JetPack 6.2.1 is installed correctly on the SSD. You can check the installation logs for any errors.
2. Check the /etc/nvpmodel.conf file: Instead of deleting the file, try editing it to enable MaxN. You can add the following line to the file: NV_POWER_MODE=0 (this will enable MaxN). Then, reboot the device.
3. Use the nvpmodel command: Run the command sudo nvpmodel -m 0 to enable MaxN. This command sets the power mode to 0, which enables MaxN.
4. Verify MaxN status: After enabling MaxN, you can verify its status using the nvpmodel command: sudo nvpmodel -q. This will display the current power mode, which should be 0 (MaxN).
5. Check jtop output: Run jtop again to see if JetPack is detected. If it’s still not detected, you may need to reinstall JetPack or seek further assistance.

If none of these steps work, you can try seeking help from the NVIDIA developer community or forums, as they may have more specific guidance or troubleshooting steps for your issue.

Hi @haddadmootaz

Have you tried changing the power mode directly in the GUI after the reboot? As mentioned on this page

And regarding the jtop problem, it might just be that the tool is not updated for that L4T version: jetson-stats not supported for [L4T 36.4.4] · Issue #679 · rbonghi/jetson_stats · GitHub

Hi,
Please do

1. Re-flash the system to Jetpack 6.2.1 through SDKManager with super mode enabled
2. Run the command: $ sudo nvpmodel -m 2
3. Reboot the system

For Orin Nano modules, MAXN_SUPER mode is mode 2 instead of mode 0 per:

Jetson Orin Nano Series, Jetson Orin NX Series and Jetson AGX Orin Series — NVIDIA Jetson Linux Developer Guide

Hi,

i updated jetson-stats from this jetson-stats not supported for [L4T 36.4.4] · Issue #679 · rbonghi/jetson_stats · GitHub to detect the JetPack and to enable MAXN_SUPER bu running this command“sudo cp /etc/nvpmodel/nvpmodel_p3767_0003_super.conf /etc/nvpmodel.con && sudo reboot”

thanks
