From the author

Use when you need to print Jetson device info (module model, L4T version, kernel, OS version, current power mode) from a running Jetson target. This is an example skill.

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a standardized method for gathering essential system information from a running NVIDIA Jetson device. It performs a read-only inspection of the device's software stack, kernel version, OS release, and current power mode. Designed as a diagnostic utility, it is intended to establish a baseline state before executing performance, regression, or compatibility tests, ensuring that the environment matches expected configurations.

What it does

  • Identifies the specific Jetson hardware model via device-tree inspection.
  • Retrieves the current L4T release version and revision.
  • Queries the active power mode and associated mode index.
  • Reports the current kernel version and system uptime.
  • Detects the underlying OS version using standard system files.
  • Validates that the host is a Jetson device before proceeding.

When to use it

  • Before running performance benchmarks to document the system state.
  • When verifying that a newly flashed device matches the target software version.
  • During troubleshooting to confirm the current power and OS configuration.
  • As a pre-test check to ensure the environment is correctly configured.

Advantages

  • Provides a consistent, human-readable report format.
  • Gracefully handles missing components without crashing.
  • Non-intrusive read-only operation ensures system stability.
  • Includes built-in validation to prevent execution on non-Jetson hardware.

Usage examples

“Print the current system information for this Jetson device.”
The agent outputs a structured report containing the model name, L4T release, power mode, kernel version, uptime, and OS version.

Documentation by Jetson Team

jetson-print-device-info

Prints a concise summary of the Jetson device this skill runs on.

This skill is intended as a reference example for the jetson-device-skills repo and the NVIDIA-wide skills CI. It runs on the Jetson target (not the host PC) and performs read-only inspection — useful as a baseline capture before running performance tests.

Purpose

Capture a baseline snapshot of a Jetson target's software stack and power mode before running performance, regression, or compatibility tests.

When to use

  • Starting a performance run and you want a captured baseline of the device's software stack and power mode.

  • Verifying that a freshly flashed Jetson matches an expected L4T / JetPack version.

Prerequisites

  • Running on a Jetson target (not the host PC).

  • Standard CLIs available: tr, cat, uname, uptime, lsb_release (or /etc/os-release).

  • nvpmodel available for power mode (optional — skill falls back gracefully).

Inputs

None. The skill reads only from the local Jetson filesystem and standard CLIs.

Instructions

Run each step in order and print the captured values into the report shown under Output format.

  1. Capture the module model and validate it is a Jetson target — exit early otherwise:

    # Device-tree strings are null-terminated, so strip NULs before printing.
    model=$(tr -d '\0' < /proc/device-tree/model 2>/dev/null)
    case "$model" in
      *Jetson*) ;;
      *) echo "Not running on a Jetson target (model: '${model:-unknown}')"; exit 1 ;;
    esac
    echo "$model"
  2. Extract the L4T release header line — skip the rest of the file (long list of library SHAs):

    head -1 /etc/nv_tegra_release 2>/dev/null || echo "L4T release info not found"
    # Equivalent: grep -m1 '^# R' /etc/nv_tegra_release
  3. Run nvpmodel -q and join its two output lines (NV Power Mode: <name> and the mode number) onto one line. paste -sd only uses the first char of its delimiter, so use awk to insert the literal / separator:

    nvpmodel -q 2>/dev/null | awk 'NR==1{a=$0; next} {print a" / "$0}' \
      || echo "nvpmodel not available"
  4. Print the kernel version and uptime:

    uname -r
    uptime -p
  5. Print the OS version (prefer lsb_release, fall back to /etc/os-release):

    lsb_release -ds 2>/dev/null || (. /etc/os-release && echo "$PRETTY_NAME") || echo "OS version not found"

Output format

Print a short report with these sections, one line each where possible:

Model:           <device-tree model string>
L4T release:     <release header line>
Power mode:      <nvpmodel name> / <mode number>
Kernel:          <uname -r>
Uptime:          <uptime -p>
OS version:      <lsb_release / /etc/os-release output>

Examples

Example output on an Orin AGX dev kit (L4T R36 / Ubuntu 22.04):

Model:           NVIDIA Jetson AGX Orin Developer Kit
L4T release:     # R36 (release), REVISION: 3.0
Power mode:      NV Power Mode: MAXN / 0
Kernel:          5.15.136-tegra
Uptime:          up 2 hours, 14 minutes
OS version:      Ubuntu 22.04.4 LTS

Example output on an AGX Thor (L4T R39 / Ubuntu 24.04):

Model:           NVIDIA Jetson AGX Thor Developer Kit
L4T release:     # R39 (release), REVISION: 0.0
Power mode:      NV Power Mode: 120W / 1
Kernel:          6.8.0-tegra
Uptime:          up 12 minutes
OS version:      Ubuntu 24.04 LTS

Error handling

Each command falls back to a clearly labeled "... not found" / "... not available" string if the underlying file or binary is missing — the skill never errors out mid-report. If /proc/device-tree/model is missing or does not contain a Jetson string, exit early with a clear "not running on a Jetson target" message.

Limitations

  • Read-only inspection only — does not detect GPU/CPU clocks, thermal state, or per-rail power.

  • nvpmodel output format varies between L4T versions; the skill prints it verbatim rather than parsing.

Troubleshooting

  • Error: /proc/device-tree/model: No such file or directory Cause: Running on a host PC, not a Jetson target. Solution: Run the skill on the Jetson device directly (e.g. via SSH).

  • Error: nvpmodel: command not found Cause: L4T BSP not installed, or running in a minimal container without nvpmodel. Solution: Expected on non-Jetson or stripped environments — the skill prints "nvpmodel not available" and continues.

Notes

  • Read-only. Do not change power mode, install packages, or modify any files.

  • If the skill is invoked on a host PC by mistake, /proc/device-tree/model will not contain a Jetson model string — detect that and exit with a clear message rather than printing misleading info.

      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade

      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,

      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
