在.reload命令之后连接丢失到目标

标签: driver windbg wdk kmdf wdm

在WinDbg:File-> Symbole文件路径?我设置路径: Srv*c:\symbols*https://msdl.microsoft.com/download/symbols 在此路径文件设置之后,我尝试制作此示例: https://msdn.microsoft.com/en-us/library/windows/hardware/mt269367 在第5节第2步中,当我键入.reload /f时,调试器丢失连接到 目标。 如果我没有设置符号文件路径,WinDbg也会在同一点上建立。

对我而言,似乎windbg失去了与目标的连接而没有得到它 又建立了。即使我在VM上重新启动目标系统。

有人能告诉我发生了什么,我做错了什么或为什么会这样?

我正在使用VMWare Player。我的主机和目标操作系统是Windows 10 Pro。 VMWare配置为在NAT中使用网络。 Echo驱动程序已成功安装。

在下面你可以看到WinDbg日志:

问题解决了。 将VM设置从以太网更改为COM。 我还使用this网站设置了将bcdedit调试设置更改为COM端口。 现在我可以调试并重新加载符号或驱动程序。
