* セットアップ [#wbca166b]
- https://developer.nvidia.com/embedded/learn/get-started-jetson-agx-orin-devkit
- 映像出力が標準サイズのDPしかなく、HDMI出力がないので、注意
- 映像出力がなくてもシリアルコンソールでセットアップ可能
- [[Getting Started with Jetson AGX Orin Developer Kit | NVIDIA Developer>https://developer.nvidia.com/embedded/learn/get-started-jetson-agx-orin-devkit]]
-- セットアップ時、電源投入後30秒ぐらいしてからファンが周り始める
-- 初回が悪かったのか、セットアップ時にコンソール画面が出ず、Jetson Orinを再起動したらコンソール画面が出た
-- 電力設定はMAXNにしておいた（全力）
$ nvpmodel -q
NV Power Mode: MAXN
0
-- NanoやXavier以前と違い、初期ユーザ名、初期パスワード、ホスト名も入力を促される
-- 適当に決めて入力する
- apt のインストール
$ time sudo apt install python-is-python3 cmake ccache tmux python3-dev python3-pip libgtk-3-dev openjdk-8-jre-headless
$ time pip install cython numpy
- ネットワークコンフィグ
- Ubuntu 18.04 からコンソールでIPのコンフィグを変える場合はnetplanが必要。
$ apt sudo apt install netplan.io
$ sudo vim /etc/n
$ sudo vim /etc/netplan/01-netcfg.yaml

-初期セットアップダイアログで変更可能だが、うっかり忘れたので、コマンドラインからセットアップし直し
sudo dpkg-reconfigure tzdata
* 拡張命令の対応 [#t7972243]
