报错一：No such file or directory: ‘dtc’
在使用 SDK Manager 刷写Jetson Linux 时，在完成了 Creating OS image 时，无法往下进行，直接报错fail。查看 Terminal 报错信息显示如下：
14:56:20 ERROR: Flash Jetson Linux - flash: File "/usr/lib/python3.8/subprocess.py", line 858, in __init__
14:56:20 ERROR: Flash Jetson Linux - flash: FileNotFoundError: [Errno 2] No such file or directory: 'dtc'
14:56:20 ERROR: Flash Jetson Linux - flash: --- Error: Reading board information failed.
14:56:20 ERROR: Flash Jetson Linux - flash: command terminated with error
14:56:20 SUMMARY: DateTime Target Setup - target: Depends on failed component
解决方案
使用 控制台刷写sudo ./nvsdkmanager_flash.sh --storage nvme0n1p1 可以看到详细错误：

--- Error: Reading board information failed.
错误消息表明程序无法找到预处理配置文件所需的“dtc”工具。这可能是由于系统上缺少或损坏了设备树编译器（dtc）的安装。
要解决此问题，可以尝试在终端中运行以下命令来重新安装dtc工具：
sudo apt-get install device-tree-compiler
这应该安装dtc工具并解决FileNotFoundError问题。安装该工具后，可以再次尝试运行该程序，看看问题是否已经解决。
报错二：ERROR sshpass not found 等其他执行刷写的依赖包
Terminal 报错并不详尽，使用控制台重试刷写操作，可以发现：
--- Reading board information succeeded.
Parsing module EEPROM:
--- Parsing board ID (3767) succeeded.
--- Parsing board version (300) succeeded.
--- Parsing board SKU (0003) succeeded.
--- Parsing board REV (L.3) succeeded.
jetson-orin-nano-devkit found.
Parsing boardid successful
Target board is jetson-orin-nano-devkit

ERROR sshpass not found! To install - please run: "sudo apt-get install sshpass"
Cleaning up...
解决方案
根据提示安装 sshpass
sudo apt-get install sshpass
同时可能还缺少其他的软件包：
sudo apt-get install abootimg
sudo apt-get install nfs-kernel-server
sudo apt-get install libxml2-utils
使用以上命令安装依赖。
结论
出现问题可以通过 Terminal 查看其执行的命令，在控制台中运行可以看到更详细的报错信息，通过这些信息可以更方便的找到问题的源头以定位处理。
另外，当使用SDKM刷写失败时，也可以直接前往操作目录，尝试直接使用命令行的方式刷写处理。
