* 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
 
 
 network:
   version: 2
   renderer: networkd

       dhcp4: yes

-JetPackのインストール
-/etc/apt/sources.list.d/nvidia-l4t-apt-source.list 内に以下の2行があるので、34.0を34.1に書き換える
 $ cat /etc/apt/sources.list.d/nvidia-l4t-apt-source.list

 $ timee udo apt update
 $ time sudo apt dist-upgrade
-しばしまつ 
 $ sudo apt install nvidia-jetpack
-タイムゾーン
-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
