RTApp 2つ = RTCore 2つ

RTApp、というかRTCoreは、アプリケーションの実行を管理する「OS」というものが存在しません。
ので、RTAppを2つ動かすということは、必然的にRTCoreを2つ使うことになります。1つ目のRTAppがRTCore #0で動いているとすると、2つ目のRTAppはRTCore #1で動かすこと。

実行するRTApp

前記事と同様、サンプルのSamples/HelloWorld/HelloWorld_RTApp_MT3620_BareMetalを使います。

1つ目のRTAppは、サンプルを未修正で使います。ビルドして出来たHelloWorld_RTApp_MT3620_BareMetal.imagepackageを、別ファイル名にコピーしておきます。

copy HelloWorld_RTApp_MT3620_BareMetal.imagepackage c:\azuresphere\HelloWorld_RTApp_MT3620_BareMetal-tick.imagepackage
        1 個のファイルをコピーしました。

2つ目のRTAppは、app_manifest.jsonのComponentIdを良い感じに変更して(w)、ついでにmain.cのシリアル送信メッセージも変更して、ビルド、コピーします。

1つ目 ... d3b80666-feaf-433a-b294-6a5846853b4a、"Tick"/"Tock"
2つ目 ... d3b80666-feaf-433a-b294-6a5846853b4b、"One"/"Two"

実行！

念のためdeleteしてから、2つのRTAppを手動でデプロイします。

C:\AzureSphere>azsphere device sideload delete

どれどれ、、、

C:\AzureSphere>azsphere device app show-status

動いているっぽい。

ロジアナで測定すると、

オォー！動いてる♪

IO0_TXDがサンプル無修正品で、IO1_TXDがサンプル修正品。

実行しているRTCoreを入れ替え

それでは、RTAppの起動順を変えてみて、実行するRTCoreが入れ替わるか見てみましょう。

C:\AzureSphere>azsphere device app stop -i d3b80666-feaf-433a-b294-6a5846853b4a
d3b80666-feaf-433a-b294-6a5846853b4a: App state: stopped

あれ！？

入れ替わらねー

デプロイ順かな？試してみます。
