[メモ] VagrantにてZephyr(RTOS)の開発環境を作って試す

概要

• Zephyr ProjectというRTOSの開発環境をVagrantで作って、サクッと試す。
• 参考: https://docs.zephyrproject.org/1.13.0/getting_started/installation_linux.html

環境

• Windows 10 Pro (1803) 64bit
• VirtualBox v5.2.18 + Extension Pack
• Vagrant v2.1.5
  • Boxベース: 'ubuntu/bionic64' (v20180919.0.0) for 'virtualbox'
• Zephyr: v1.13.0

end

手順

開発環境セットアップ

1. VirtualBoxとVagrantをインストールして、使えるようにする
2. 適当なフォルダを作って、↑のVagrantfile作成
3. vagrant up && vagrant reload
4. 待つ (20分～)

サンプルアプリのビルド(Hello World)

qemu_cortex_m3環境にて

1. vagrant ssh
   にてログイン

2. 以下実行

   cd $ZEPHYR_BASE/samples/hello_world
   mkdir build && cd build
   # cmakeを使ってNinjaベースのビルドシステムを設定:
   cmake -GNinja -DBOARD=qemu_cortex_m3 ..
   # 生成されたビルドシステムにて、ninjaを実行:
   ninja
   ninja run
   

3. Hello World! armが表示される. CTRL-A, x にてqemuを抜ける

   実行例

   vagrant@ubuntu-bionic:~/zephyr/samples/hello_world/build$ ninja run
   [0/1] To exit from QEMU enter: 'CTRL+a, x'[QEMU] CPU: cortex-m3
   ***** Booting Zephyr OS zephyr-v1.13.0 *****
   Hello World! arm
   QEMU: Terminated
   vagrant@ubuntu-bionic:~/zephyr/samples/hello_world/build$
   
   

hello_worldのソースコード

• main.c

  void main(void)
  {
          printk("Hello World! %s\n", CONFIG_ARCH);
  }
