我在目标中使用主机部署和调试驱动程序（win10 virtualbox，通过serialport 1，baudrate：115200），我可以将驱动程序加载到目标并使用命令“！lmi filedisk”进行检查，它已被加载。但它没有达到任何突破点。 我检查了“.reload -f”然后出现了：

You can troubleshoot most symbol related issues by turning on symbol loading diagnostics (!sym noisy) and repeating the command that caused symbols to be loaded.
You should also verify that your symbol search path (.sympath) is correct.
我该如何解决这个问题？
答案 0 :(得分：1)
这是第三方驱动程序/ DLL（一些来自Oracle VirtualBox和其他第三方DLL），这些驱动程序在Microsoft Symbol Server上不可用。
drmk.sys是Microsoft受信任的音频驱动程序，对于某些音频/ DRM相关文件，Microsoft也没有提供PDB来防止逆向工程。
对于您自己的驱动程序，您必须将自己的PDB添加到符号搜索路径中。
答案 1 :(得分：0)
似乎符号路径中的所有目录都不包含此驱动程序的符号文件。这就是为什么不能设置断点的原因。
确保在目录中有此驱动程序符号，然后通过执行命令.sympath + [符号目录的完整路径]将此目录添加为符号路径的一部分
