CANoe中使用CAPL函数接口调用Vflash文件

• CAPL中集成了下面那么多调用vFlash的相关函数，其实实际用到的，可能就三五个函数

• 使用这些函数接口必须要在测试模块里面加载VFLASHNODELAYER.DLL
  

• Vector官方有Demo可以学习： C:\\Users\\Public\\Documents\\Vector\\vFlash\\8\\Examples\\vFlash with CANoe\\vFlashViaNodeLayer

• 打开之后，CANoe和Vflash的通道都配置一样（这个工程需要真实总线环境，simulation不行）

• 直接运行测试用例，可以看到Trace有数据，测试pass

• 为什么即使没接真实的件，他也能有报文和刷写呢？因为simulation中它模拟节点做了应答
  
• Demo中的测试用例呢，就调用了"vFlash\\Utilities.cin"中的 TestWaitForvFlashPackReprogrammed函数就完成了刷写

• 再看下TestWaitForvFlashPackReprogrammed函数按照下面步骤完成的刷写
• TestWaitForvFlashInitialized：初始化vFlash
• TestWaitForvFlashProjectLoaded :加载.vflashPack工程
• TestWaitForvFlashProjectLoaded :开始刷写
• TestWaitForvFlashProjectUnloaded：卸载工程文件
• TestWaitForvFlashDeinitialized：xxx

// Performs all necessary steps to reprogram the passed vFlashPack
// This function will wait until reprogramming has completed (it cannot be used in a simulation node)
enum vFlashStatusCode TestWaitForvFlashPackReprogrammed(char flashpack[])

// Test functions are only available in test modules!
#if TEST_NODE
  enum vFlashStatusCode lastStatusCode;
  enum vFlashStatusCode resultCode;
  char errorText[gkMaxErrorTextLength];
  int hasProjectLoaded = 1;

  if (!ProcessPathName(flashpack)) 
    snprintf(errorText, gkMaxErrorTextLength, "FATAL ERROR: No path to flashpack given!");
    write(errorText);   
    TestStepFail("TestWaitForvFlashInitialized", errorText);
    return FR_FileNotFound; 
  
  
  //----- Initialize vFlash Library -----
  lastStatusCode = resultCode = (enum vFlashStatusCode) TestWaitForvFlashInitialized();
  if (lastStatusCode != Success)
  
    TestWaitForvFlashLastErrorMessage(errorText, 1024);
    snprintf(errorText, gkMaxErrorTextLength, "vFlash initialization error: %s", errorText);
    write(errorText);
    TestStepFail("TestWaitForvFlashInitialized", errorText);
    return resultCode;
  
  else
  
    TestStepPass("TestWaitForvFlashInitialized", "vFlash initialized successfully");
  
  
  
  // from here on, return statements are not possible, because we have to call the "teardown" methods as well!
  // ==> how much complicated want we to be...
  
  //----- Load Project ----
  lastStatusCode = resultCode = (enum vFlashStatusCode) TestWaitForvFlashProjectLoaded(_gFlashpack);
  if (lastStatusCode != Success)
  
    hasProjectLoaded = 0;
    TestWaitForvFlashLastErrorMessage(errorText, 1024);
    snprintf(errorText, gkMaxErrorTextLength, "vFlash load project error: %s", errorText);
    write(errorText);
    TestStepFail("TestWaitForvFlashProjectLoaded", errorText);
  
  else
  
    TestStepPass("TestWaitForvFlashProjectLoaded", "Successfully loaded project: %s", _gFlashpack);
  
  
  
  //----- Activate Network
  // Activation of this function call is only required in case of flashing a FlexRay ECU 
  // and vFlash has to do Network Management
  if (lastStatusCode == Success)
  
    lastStatusCode = resultCode = (enum vFlashStatusCode) TestWaitForvFlashNetworkActivated();
    if (lastStatusCode != Success)
    
      TestWaitForvFlashLastErrorMessage(errorText, 1024);
      snprintf(errorText, gkMaxErrorTextLength, "vFlash activate network error: %s", errorText);
      TestStepFail("TestWaitForvFlashNetworkActivated", errorText);
      write(errorText);
    
    else
    
      TestStepPass("TestWaitForvFlashNetworkActivated", "Network activated successfully");
    
  
  
  
  //----- Start Reprogramming ----
  if (lastStatusCode == Success)
  
    lastStatusCode = resultCode = (enum vFlashStatusCode) TestWaitForvFlashReprogrammed();
    if (lastStatusCode != Success)
    
      TestWaitForvFlashLastErrorMessage(errorText, 1024);
      snprintf(errorText, gkMaxErrorTextLength, "vFlash reprogramming error: %s", errorText);
      TestStepFail("TestWaitForvFlashReprogrammed", errorText);
      write(errorText);
    
    else
    
      TestStepPass("TestWaitForvFlashReprogrammed", "ECU reprogrammed successful");
    
  

  
  //----- Unload Project ----
  if (hasProjectLoaded)
  
    lastStatusCode = (enum vFlashStatusCode) TestWaitForvFlashProjectUnloaded();
    if (lastStatusCode != Success)
        
      TestWaitForvFlashLastErrorMessage(errorText, 1024);
      snprintf(errorText, gkMaxErrorTextLength, "vFlash unload project error: %s", errorText);
      TestStepFail("TestWaitForvFlashProjectUnloaded", errorText);
      write(errorText);
    
    else
    
      TestStepPass("TestWaitForvFlashProjectUnloaded", "Project unloaded successfully");
       
  
  
  
  //----- Deinitialize vFlash Library ----
  lastStatusCode = (enum vFlashStatusCode) TestWaitForvFlashDeinitialized();
  if (lastStatusCode != Success)
  
    TestWaitForvFlashLastErrorMessage(errorText, 1024);
    snprintf(errorText, gkMaxErrorTextLength, "vFlash deinitialization error: %s", errorText);
    TestStepFail("TestWaitForvFlashDeinitialized", errorText);
    write(errorText);
  
  else
  
    TestStepPass("TestWaitForvFlashDeinitialized", "vFlash deinitialized successfully");
  
    
  return resultCode; // last result is of TestWaitForvFlashReprogrammed; result of Unload/Deinitialize ignored
#else // simulation node
  write( "ERROR: the function TestWaitForvFlashPackReprogrammed is only available in a test module!");
  return TestFunctionInSimulationCalled;
#endif // TEST_NODE

• 如果想要刷写自己的vFlash文件，简单的话就是把 gFlashpack给个自己文件的路径即可；想要集成在自己工程中用的话，要引用 #include "vFlash\\Utilities.cin"，调用 TestWaitForvFlashPackReprogrammed函数即可。

• 自己调用的时候，别忘了要在测试模块中加载下面的DLL
