# NVIDIA JetPack SDK 下载与说明 ## JetPack 7.1 搭载 Jetson Linux 38.4 在此页面可获取 NVIDIA JetPack™ SDK 与 NVIDIA Jetson™ Linux 的发行说明、可下载软件包，以及开发与量产相关资源。 下载并使用软件，即表示您同意完全遵守 [NVIDIA 软件许可协议](https://developer.download.nvidia.com/compute/mathdx/License.txt)。 [下载 JetPack ISO 镜像](https://developer.nvidia.com/downloads/embedded/L4T/r38_Release_v4.0/release/jetsoninstaller-r38.4.0-2025-12-30-17-00-37-arm64.iso)[下载 SDK Manager](/sdk-manager) **1. 注意：请参阅 [Jetson AGX Thor 开发者套件快速入门指南](https://docs.nvidia.com/jetson/agx-thor-devkit-4fed1671/user-guide/latest/quick_start.html)刷写步骤和 [Jetson Linux 开发者指南](http://docs.nvidia.com/jetson/archives/r38.4/DeveloperGuide/)(刷写支持部分) ，适用于开发者套件和生产模块的所有刷写方法。** ## ## 版本信息 本节提供有关最新 JetPack 版本的关键详细信息，包括版本亮点、新功能、受支持的 Jetson 平台，以及面向开发者和生产部署的重要更新。 ### 新增功能 注意：有关完整详细信息，请参阅 [Jetson Linux 版本说明](https://docs.nvidia.com/jetson/archives/r38.4/ReleaseNotes/Jetson_Linux_Release_Notes_r38.4.pdf)。 Jetson Linux 38.4 是支持 NVIDIA JetPack™ 7.1 的最新 Jetson Linux 版本。以下是此版本的亮点： 1. 支持 Jetson T4000 模组 2. 支持视频编解码器 SDK 3. 支持 TensorRT EdgeLLM **博客文章** ：有关此版本主要功能的更多信息，请[单击此处](https://developer.nvidia.cn/blog/accelerate-ai-inference-for-edge-and-robotics-with-nvidia-jetson-t4000-and-nvidia-jetpack-7-1/)参阅支持此版本的博客文章。 **注意事项** ： - 借助 JetPack 7 系列，Jetson 软件与服务器基础系统架构 (SBSA) 保持一致，将 Jetson Thor 与行业标准 ARM 服务器设计结合起来。SBSA 可标准化关键硬件和固件接口，提供更强大的操作系统支持、更简单的软件可移植性和更流畅的企业集成。在此基础上，Jetson Thor 现在支持在所有 Arm 目标中安装统一的 CUDA 13.0，从而简化开发、减少碎片化，并确保从服务器级系统到 Jetson Thor 的一致性。 - 由于 Thor 利用了 SBSA 架构，手动刷写指令略有变化。请仔细阅读手动刷写说明。 ### 支持的硬件 Jetson AGX Thor 开发者套件 Jetson T5000 Jetson T4000 ### 支持的库与 SDK 版本 | Operating System | Jetson Linux | 38.4 | | Kernel | k6.8 | | Distro | L4T Ubuntu 24.04 | | Other Supported Linux Distros | Canonical Ubuntu 24.04 for Jetson | | AI Compute | NVIDIA CUDA® | 13.0.0 | | CuDNN | 9.12.0 | | NVIDIA TensorRT™ | 10.13.2.6 | | Graphics | Vulkan | 1.4 | | Vulkan SC | 1.0 | | OpenWF DIsplay | Not supported | | OpenGL | 4.6 | | OpenGLES | 3.2 | | GLX | 1.4 | | EGL | 1.5 | | Multimedia | V4L2 | 1.22.1 | | Computer Vision | VPI | 4.0.0 | | PVA | 2.7.1 | | NVIDIA Nsight™ Developer Tools | Nsight Systems | 2025.4 | | Nsight Graphics | 2025.3 | | Nsight Deep Learning Designer | 2025.2 | | Nsight Perf SDK | 2025.4 | | Supported SDKs and Tools | Jetson Platform Services | Coming soon | | NVIDIA DeepStream SDK | 8.0 | | NVIDIA Isaac™ ROS | Coming soon | | NVIDIA Holoscan SDK | 3.9.0 | | NVIDIA Triton™ Inference Server | [Triton Container](https://catalog.ngc.nvidia.com/orgs/nvidia/containers/tritonserver) | | Power Estimator | 2.7 | | NVIDIA Container Toolkit | 1.18 (w/ ISO image) | ### Jetson Linux 下载与文档 NVIDIA® Jetson™ Linux 驱动包是 Jetson 的板级支持包。它包括 Linux 内核、UEFI 引导加载程序、NVIDIA 驱动程序、刷写实用程序、基于 Ubuntu 的示例文件系统，以及适用于 Jetson 平台的更多内容。 | #### Jetson Linux 38.4 (1/06/2026) | | --- | | Drivers | [Driver Package (BSP)](https://developer.nvidia.com/downloads/embedded/L4T/r38_Release_v4.0/release/Jetson_Linux_R38.4.0_aarch64.tbz2) | | [Camera SIPL](https://developer.nvidia.com/downloads/embedded/L4T/r38_Release_v4.0/release/Jetson_SIPL_API_R38.4.0_aarch64.tbz2) | | [Sample Root Filesystem](https://developer.nvidia.com/downloads/embedded/L4T/r38_Release_v4.0/release/Tegra_Linux_Sample-Root-Filesystem_R38.4.0_aarch64.tbz2) | | [Jetson Linux API Reference](https://developer.nvidia.com/downloads/embedded/L4T/r38_Release_v4.0/release/Jetson_Multimedia_API_R38.4.0_aarch64.tbz2) | | Sources | [Driver Package (BSP) Sources](https://developer.nvidia.com/downloads/embedded/L4T/r38_Release_v4.0/source/public_sources.tbz2) | | [Sample Root Filesystem Sources](https://developer.nvidia.com/downloads/embedded/L4T/r38_Release_v4.0/source/ubuntu_noble-l4t_aarch64_src.tbz2) | | Tools | [WebRTC](https://developer.nvidia.com/downloads/embedded/L4T/r38_Release_v4.0/release/WebRTC_R38.4.0_aarch64.tbz2) | | [Crosstool-NG Toolchain gcc](https://developer.nvidia.com/downloads/embedded/L4T/r38_Release_v2.0/release/x-tools.tbz2) | | [Crosstool-NG Toolchain Sources](https://developer.nvidia.com/downloads/embedded/L4T/r38_Release_v2.0/sources/crosstool-ng-jetson.tbz2) | | [CUDA Tools](/cuda-toolkit) | | [NVIDIA Nsight Systems](https://developer.nvidia.com/nsight-systems/get-started) | | [NVIDIA Nsight Graphics](/nsight-graphics) | | [FSKP Tools](https://developer.nvidia.com/downloads/embedded/L4T/r38_Release_v4.0/release/host_overlay_fskp_tools_R38.4.0_aarch64.tbz2) | | [OTA Tools](https://developer.nvidia.com/downloads/embedded/L4T/r38_Release_v4.0/release/ota_tools_R38.4.0_aarch64.tbz2) | | Documents | [Jetson Linux Release Notes](https://docs.nvidia.com/jetson/archives/r38.4/ReleaseNotes/Jetson_Linux_Release_Notes_r38.4.pdf) | | [Jetson Linux Developer Guide](https://docs.nvidia.com/jetson/archives/r38.4/DeveloperGuide/index.html) | | [Jetson Linux API Reference](https://docs.nvidia.com/jetson/archives/r38.4/ApiReference/index.html) | | [Jetson AGX Thor Developer Kit User Guide](https://docs.nvidia.com/jetson/agx-thor-devkit-4fed1671/user-guide/latest/quick_start.html) | | [Camera Development Guide](https://docs.nvidia.com/jetson/archives/r38.4/DeveloperGuide/SD/CameraDevelopment/CoECameraDevelopment.html) | | [Software License Agreement](https://developer.nvidia.com/downloads/embedded/L4T/r38_Release_v4.0/release/Tegra_Software_License_Agreement-Tegra-Linux.txt) | 有关 JetPack 或 Jetson Linux 的旧版本，请访问 [JetPack 存档](https://developer.nvidia.cn/embedded/jetpack-archive)或 [Jetson Linux 存档](https://developer.nvidia.cn/embedded/jetson-linux-archive)。
