• 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_NODEenum 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 Managementif (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 nodewrite( "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
