1，资源包下载

下载路径：

Jetson Linux R32.7.6 | NVIDIA Developer

2，解压资源

root@ubuntu:/home/xu/nano_2025/32.7.6_org# sudo tar -xvjf jetson-210_linux_r32.7.6_aarch64.tbz2 
root@ubuntu:/home/xu/nano_2025/32.7.6_org# ls
jetson-210_linux_r32.7.6_aarch64.tbz2  Linux_for_Tegra  overlay_32.7.5_PCN211181.tbz2  public_sources.tbz2  Tegra_Linux_Sample-Root-Filesystem_R32.7.6_aarch64.tbz2

3，解压文件系统，注意路径

root@ubuntu:/home/xu/nano_2025/32.7.6_org# cd Linux_for_Tegra/rootfs/
root@ubuntu:/home/xu/nano_2025/32.7.6_org/Linux_for_Tegra/rootfs# ls
README.txt
root@ubuntu:/home/xu/nano_2025/32.7.6_org/Linux_for_Tegra/rootfs# sudo tar -xjf ../../Tegra_Linux_Sample-Root-Filesystem_R32.7.6_aarch64.tbz2 
root@ubuntu:/home/xu/nano_2025/32.7.6_org/Linux_for_Tegra/rootfs# ls
bin  boot  dev  etc  home  lib  media  mnt  opt  proc  README.txt  root  run  sbin  snap  srv  sys  tmp  usr  var

4，安装部署

root@ubuntu:/home/xu/nano_2025/32.7.6_org/Linux_for_Tegra/rootfs# cd ..
root@ubuntu:/home/xu/nano_2025/32.7.6_org/Linux_for_Tegra# 
root@ubuntu:/home/xu/nano_2025/32.7.6_org/Linux_for_Tegra# sudo ./apply_binaries.sh
root@ubuntu:/home/xu/nano_2025/32.7.6_org/Linux_for_Tegra# cd ..
root@ubuntu:/home/xu/nano_2025/32.7.6_org#

apply_binaries.sh是NVIDIA Jetson开发工具包中的一个关键脚本，主要作用是将预编译的二进制文件（如内核模块、固件、库文件等）部署到解压后的根文件系统中。具体功能包括：

‌内核模块安装‌：将NVIDIA专有驱动模块（如GPU、视频编解码器等）安装到/lib/modules目录
‌固件部署‌：拷贝设备所需的固件文件（如WiFi/蓝牙模块固件）到/lib/firmware
‌库文件配置‌：安装CUDA、TensorRT等AI加速库到系统路径
‌设备树更新‌：为Jetson硬件生成对应的设备树二进制文件(.dtb)
‌权限设置‌：确保关键设备节点（如/dev/nvhost*）具有正确的访问权限

该脚本通常在解压根文件系统后执行，是完成Jetson系统烧录前的必要步骤。

5，2025 年之后需安装补丁

6，到这一步大部分板卡可以正常烧录

部分板卡需要修改tegra210-p3448-0002-p3449-0000-b00.dtb

修改方法：

sudo dtc -I dtb -O dts -o tegra210-p3448-0002-p3449-0000-b00.dts tegra210-p3448-0002-p3449-0000-b00.dtb

编译回dtb 文件

sudo dtc -I dts -O dtb -o tegra210-p3448-0002-p3449-0000-b00.dtb tegra210-p3448-0002-p3449-0000-b00.dts

7，烧写

我这里采用路径和方法：

root@ubuntu:/home/xu/nano_2025/32.7.6/Linux_for_Tegra# sudo ./flash.sh  jetson-nano-devkit-emmc mmcblk0p1
