本博文 主要记录 本博对JetsonTX2的刷机心路历程（JetPack4.5 2021年1月22日）
1. 购买了JetsonTX2开发套件一套、JetsonTX2核心板与对应的小开发板，JetsonTX2开发套件主要目的是在实验室里进行算法测试与验证，JetsonTX2核心板与对应的小开发板主要目的是往无人机上移植，如下：
2. JetsonTX2开发套件自带系统，自带JetPack4.3（L4T 32.3.1），开发套件开机并查看，打开终端，输入版本查看命令：head -n 1 /etc/nv_tegra_release
3. 其他的东西要么没有，要么没刷进去，比如cuda版本为6，太低了，TensoRT就压根没有！ 天无绝人之路，哥要刷机！ 刷机！ 刷机！
4. 下载sdkmanager，我下载最新的sdkmanager_1.4.0-7363_amd64.deb地址为：
https://developer.nvidia.com/embedded/jetpack-archive 需要账户登录并下载，这个账户后面还要用，是必须要的。
5. 提前准备一台机器，笔记本或台式机，我们暂称之为上位机，在上位机中安装（Ubuntu18.04-LTS 8G内存需求，若虚拟机请将磁盘容量至少设置在60G以上，内存8G），sdkmanager，命令：
$ sudo apt install ./sdkmanager_1.4.0-7363_amd64.deb
$ sdkmanager
6. 登录（常规操作）
登录正常应该如下界面，但是，如果…… 出现以下界面主要原因是靠脸，脸好看就会出现以下界面！ 可偏偏，本博脸比上不足比下有余，实属难看，所以没给给我以下的界面，而是给了下面这张界面后的界面，显示：OOPS ！ No SDK on you account! …… 命不好，没办法！
我问你怎么办？怎么办？怎么办？我该怎么办？怎么办？怎么办？
反正呢，我是解决了，怎么解决的我要保密，但是我可以悄悄地告诉你一部分：
sdkmanager安装好后，在~/.nvsdkm/sdkm.log文件，你只需要，在终端输入：
$ sudo tail -f ~/.nvsdkm/sdkm.log
一边登录sdkmanager，就可以在终端中显示相关信息了，主要是看Failed和Error信息，看完你就明白了，至此打住，别问！别问！别问！！！
6. 不用更换上位机的源，JetPack4.5相关的文件我已经提前下载好，放置于百度网盘中，共61个文件+2个JSON配置文件，共计63个文件，需要的话，就请留言，我回贴出来的，要就要留言！要就要留言！要就要留言！保证给！保证给！保证给！ 你只需要，在home下，新建jetpack4.5/nvidia/nvidia_download 和jetpack4.5/nvidia/nvidia_sdk
将下载好的63个文件 放置在jetpack4.5/nvidia/nvidia_download中，怎么放进去，你自己看着办！你自己看着办！你自己看着办！
7. 然后就是正常刷机了，网上教程千篇一律，自己去“偷看”，我就不搬砖了！不搬砖了！不搬砖了！
8. 其他的问题，就是保证上位机与JetsonTX2在同一个局域网中！
9. 其他的问题，在刷机开机后，配置TX2网络同时开启ssh服务，需要保证上位机终端能够 ssh JetsonTX2-name@IP 访问，该重启就得重启！
10. 其他的问题，若上位机是虚拟机，可能会出现，tlp问题，显示如“0955:7c18”，需要编辑/etc/default/tlp 新增如下，然后重启！
USB_BLACKLIST=” 0955:7c18”
11. 在下位机TX2 输入法安装: $ sudo apt-get install fcitx-googlepinyin
12. 在下位机TX2 安装 TX2监控软件包 jetson-stats，你会发现别有洞天：
$ sudo apt-get install python3-pip
$ sudo pip3 install jetson-stats
$ sudo jtop
13. 刷完机，若你需要换源，你自己决定，自己看着办！自己看着办！自己看着办！
算了，还是贴出那61个文的下载地址吧，若自己网速好，就自己下，尽量不要觊觎我的网盘地址，真有必要，就留言吧！
