JetPack Not Detected Issue on AGX Orin

[suhyun01150]

hello. I am using an AGX Orin, and jtop was working fine until suddenly, it started showing “JetPack not detected.”

Here is the output of the following command:
dpkg -l | grep nvidia-jetpack
ii nvidia-jetpack 6.1+b123 arm64 NVIDIA Jetpack Meta Package
ii nvidia-jetpack-dev 6.1+b123 arm64 NVIDIA Jetpack dev Meta Package
ii nvidia-jetpack-runtime 6.1+b123 arm64 NVIDIA Jetpack runtime Meta Package

echo $JETPACK_VERSION
R36

cat /etc/nv_tegra_release

R36 (release), REVISION: 4.3, GCID: 38968081, BOARD: generic, EABI: aarch64, DATE: Wed Jan 8 01:49:37 UTC 2025

KERNEL_VARIANT: oot

TARGET_USERSPACE_LIB_DIR=nvidia
TARGET_USERSPACE_LIB_DIR_PATH=usr/lib/aarch64-linux-gnu/nvidia

Even after multiple reboots, the issue still persists. What should I do?

Also, I am specifically using the AGX Orin Developer Kit (not a carrier board).

Hi suhyun01150,

@suhyun01150

jtop was working fine until suddenly,

Do you know if any operation causes this issue?
(i.e. how do you reproduce the issue on the devkit?)

It seems like an issue specific to jtop tool since it can be read from the sysfs /etc/nv_tegra_release
Please also share /var/log/syslog from your board for further check.

Suddenly, when I launched jtop, it displayed this message and is no longer being detected. I don’t know why it shows ‘not detected.’ Since the syslog is over 200MB, I saved it using strings /var/log/syslog | grep -i jetpack > jetpack_log.txt. Will that work?
jetpack_log.txt (154.4 KB)

Can anyone help? Is going back to Flash with the SDK really the only option?

What version of jtop do you have? you could try
updating jtop to version 4.3.1 dated 1/16/25 ?

    sudo pip3 install -U jetson-stats

Then logout/login or reboot your orin.
