NVIDIA Jetson Orin - JetPack 5.0.2 - Getting Started - Components
|
This section provides an overview of some of the main software components in Jetpack 5.0 for the Orin AGX.
Jetpack Components
Linux for Tegra
Linux for Tegra (L4T) is the component that provides the OS components (kernel, file system, drivers, firmware) and the bootloader. Jetpack 5.0 comes with L4T version 34.1, featuring:
- Linux Kernel version 5.10: the previous Jetpack version (4.6) came with Linux Kernel version 4.9.
- Ubuntu 20.04-based root file system: the previous Jetpack version (4.6) came with Ubuntu 18.04-based root file system.
- UEFI-based bootloader: CBoot was used prior to L4T 34.1.
- Jetson Orin NX performance emulation on Jetson AGX Orin:
- Support for NVSCI: Provides utilities for streaming data packets between different applications and for inter-process communication (IPC)
- Jetson Power GUI: a new tool for monitoring the power and thermal status of the Jetson platform.
TensorRT
TensorRT is a framework created and published by NVIDIA for deep learning inference runtime. Jetpack 5.0 Developer Preview includes TensorRT 8.4.0 Early Access (EA). This EA is for early testing and feedback. For production, the documentation recommends continuing to use TensorRT 8.2.3 or later TensorRT 8.2.x patch.
TensorRT 8.4.0 EA has been tested with the following:
- cuDNN 8.3.2
- TensorFlow 1.15.5
- PyTorch 1.9.0
CUDA
CUDA Toolkit provides a comprehensive development environment for C and C++ developers building GPU-accelerated applications. The toolkit includes a compiler for NVIDIA GPUs, math libraries, and tools for debugging and optimizing the performance of your applications.
Starting with CUDA 11, the various components in the toolkit are versioned independently.

Multimedia API
The Jetson Linux API Reference describes several APIs or API extensions that are implemented in NVIDIA® Jetson™ Linux Driver Package (L4T). You can use these APIs to customize aspects of your Jetson device's behavior.
Camera application API: libargus offers a low-level frame-synchronous API for camera applications, with per frame camera parameter control, multiple (including synchronized) camera support, and EGL stream outputs. RAW output CSI cameras needing ISP can be used with either libargus or GStreamer plugin. In either case, the V4L2 media-controller sensor driver API is used.
The Multimedia APIs are separate from the GStreamer framework, which provides high-level APIs. That framework is included in current and previous releases.
JetPack 5.0 Developer Preview Multimedia highlights include:
- New NVUtils Multimedia buffer management and buffer transformation API.
