1 Erika Enterprise RTOS簡介

Erika Enterprise是一個免專利的汽車OSEK/VDX認證的硬實時作業系統(RTOS)。官網連結：http://www.erika-enterprise.com/

1.1 主要特性

最新版本介紹：

注意：雖然Erika Enterprise的V2和V3版本都支援多核晶片處理，但是V2版本需要在每一個核上各自運作一份Erika RTOS代碼，這和FreeRTOS的多核應用是類似的；而V3版本則支援晶片内所有核共用一份Erika RTOS代碼。

1.2 Erika Enterprise下載下傳

選中其中的三個“Accept”選項後點選“Submit Form”按鍵進入到如下圖所示界面：

開發人員可根據需要下載下傳對應版本的開發環境。

2 開發環境

2.1 開發環境配置及使用

有關Erika Enterprise開發環境的配置和使用可參考官網提供的資料進行。

Quick start guide：

http://www.erika-enterprise.com/wiki/index.php?title=Quick_start_guide

Application example：

http://www.erika-enterprise.com/wiki/index.php?title=AVR8_-_Arduino_application_build_on_Windows

2.2 開發環境簡介

按照官方提供Quick start guide完成配置後會在桌面生成IDE圖示：

• Eclipse系IDE，基于Workspace進行Project開發
• 根據選用晶片直接生成工程例程
• 與OSEK系統的使用類似，IDE中提供OIL（OSEK Implementation Language）檔案設定界面
• 系統的使用，包括CPU設定、任務建立、異步通信設定等在OIL檔案中設定，通過IDE生成源碼檔案

2.3 工程檔案介紹

以Infineon TC297晶片建立工程為例，工程檔案目錄如下圖所示：

工程OIL檔案（conf.oil）舉例說明：

當配置使用晶片的多個核時，需在oil檔案中對多個核進行設定：

CPU_DATA = TRICORE {
  ID = 0x0;
  CPU_CLOCK = 200.0;
  COMPILER = GCC;
  IDLEHOOK = TRUE {
    HOOKNAME = "idle_hook_core0";
  };
};

CPU_DATA = TRICORE {
  ID = 0x1;
  MULTI_STACK = TRUE;
  IDLEHOOK = TRUE {
    HOOKNAME = "idle_hook_core1";
  };
};

CPU_DATA = TRICORE {
  ID = 0x2;
  IDLEHOOK = TRUE {
    HOOKNAME = "idle_hook_core2";
  };
};
