新版NANO下载烧录过程

一、序言

搭建 Jetson 系列产品烧录系统的环境需要在电脑主机上安装 Ubuntu 系统。此处使用 18.04 LTS。

二、环境搭建

1、安装库

$ sudo apt-get install qemu-user-static$ sudo apt-get install python

搭建环境的过程需要这个应用库来将某些 NVIDIA 软件组件安装到 Jetson开发工具包中。

2、从 NVIDIA 官网下载所需版本的驱动程序包和文件系统包

Jetson Linux Archive | NVIDIA Developer

特别注意：32.7.5 之后，对应2025批次nano。

此处，我不编译内核，只是做烧写用所有只下载：Driver Package (BSP) 和 Sample Root Filesystem

32.7.5 之后版本需下载，页面最下方：Overlay_PCN211181_r32.7.5.tbz2

根据自己对应的 Jetson 设备下载对应的驱动程序包，和根文件系统包。
Driver Package(BSP) 程序包名称为 jetson-210_linux_r32.7.6_aarch64.tbz2，程序包名中 R32.7.6 表示的是对应的版本。
根文件系统包名称为 Tegra_Linux_Sample-Root-Filesystem_R32.7.6_aarch64.tbz2 。
在下载时请注意下载对应目标 Jetson 设备栏目下的驱动程序包及根文件系统。

3、在 Ubuntu 创建并进入工作目录：

$ mkdir 32.7.6&cd 32.7.6

并将下载好的驱动程序包和根文件系统包拷贝到工作目录下。

4、在工作目录（32.7.6 目录）下执行以下命令，解压驱动程序包。

xu@ubuntu:~/nano_2025/32.7.6$ tar -xvf jetson-210_linux_r32.7.6_aarch64.tbz2

5、解压完成过后，会得到系统烧写目录（Linux_for_Tegra），进入 Linus_for_ Tegra 目录下的 rootfs 目录 cd Linux_for_Tegra/rootfs 在 rootfs 目录下执行以下命令，解压根文件系统包：

xu@ubuntu:~/nano_2025/32.7.6$ cd Linux_for_Tegra/rootfs/
xu@ubuntu:~/nano_2025/32.7.6/Linux_for_Tegra/rootfs$ sudo tar -xpvf ../../Tegra_Linux_Sample-Root-Filesystem_R32.7.6_aarch64.tbz2

6、等待解压完成，返回到系统烧写目录，并在系统烧写目录（Linux_for_Tegra）下执行以下命令，安装 NVIDIA 应用库：

等待安装完成即可。

7、返回到工作目录32.7.6，把jetson nano模组补丁文件 overlay_32.7.5_PCN211181.tbz2 拷贝到工作目录下，执行以下命令解压补丁文件：

xu@ubuntu:~/nano_2025/32.7.6$ sudo tar --overwrite -xvf overlay_32.7.5_PCN211181.tbz2
