今回詰まったところ ● そもそも AGL
の最新ソース(CES2017 Demo の AGL UCB 3.0.2) の在り処を探すのに手間取った。。 ○ elinux( http://elinux.org/R-Car/Boards/Porter ) は UCB 2.1 まで ○ AGL wiki Porter (https://wiki.automotivelinux.org/start/building_for_the_renesas_r-car_m2) は 2.0.4 まで ○ → AGL wiki のリリースノート https://wiki.automotivelinux.org/agl-distro/release-notes の バー ジョン毎のリポジトリ URL のリストから最新版 URL を入手 ● Ubuntu 14.04 の tar の version をあげる必要 ○ デフォルト ■ $ tar --version ■ tar (GNU tar) 1.27.1 ○ AGL としては tar 1.28 を使えとのこと ○ →適当にアップデートして対応
17.
まとめ ● AGL on
Yocto on R-Car M2 Porter ビルド&実行出来ましたね! ○ AGL(Automotive Grade Linux) = Linux Faundation 策定の車載用 Linux ○ Yocto Project = 組込 Linux 作成環境 ○ R-Car M2 Porter = ルネサスさんの車載用 SoC ● AGL on Yocto の良いところ ○ (理念とか方向性とかそういう良さはここでは語らず、 Yocto ユーザー視点として ) ○ 圧倒的にビルドコマンドが少ない!簡単! ● 個人的には Yocto の情報もっと潤沢になって欲しいと思っているので、 Yocto 人 口が増えたら嬉しいです! ○ 最初は RPi3 とかでビルド済の OS がネットに上がってる実機がおすすめです
