Common WinDbg Commands (Thematically Grouped), by Robert Kuster. 4) Expressions and commands; Cmd Variants / Params Description; Command separator (cm1; cm2;.).
Debug Universal Drivers - Step- by- Step Lab (Echo Kernel Mode)This lab introduces the Win. Dbg kernel debugger. Win. Dbg is used to debug the echo kernel mode sample driver code. Lab objectives. This lab includes exercises that introduce the debugging tools, teach common debugging commands, illustrate the use of break points, and show the use of the debugging extensions.
In this lab, a live kernel debug connection is used to explore the following: Use the Windows debugger commands. Use standard commands (Call stacks, variables, threads, IRQL)Use advanced driver debugging commands (! Use symbols. Set breakpoints in live debugging. View call stacks.
Display the Plug and Play device tree. Work with thread and process context. Note When working with the Windows debugger, there are two types of debugging that can be performed - user or kernel mode debugging.
Processes that run in user mode do so within their own virtual address spaces. They are restricted from gaining direct access to many parts of the system, including system hardware, memory that was not allocated for their use, and other portions of the system that might compromise system integrity. Because processes that run in user mode are effectively isolated from the system and other user mode processes, they cannot interfere with these resources. Kernel mode - Kernel mode is the processor access mode in which the operating system and privileged programs run. Kernel mode code has permission to access any part of the system, and is not restricted like user mode code. It can gain access to any part of any other process running in either user mode or kernel mode.
Much of the core OS functionality and many hardware device drivers run in kernel mode. This lab will focus on kernel mode debugging, as that is the method used to debug many device drivers. This exercise covers debug commands that are frequently used during both user- mode and kernel- mode debugging.
The exercise also covers debug extensions (sometimes called . Windows debugger runs on the host system and the KMDF Echo driver runs on the target system. The . For information about how to use the Ethernet transport protocol, see Getting Started with Win.
Dbg (Kernel- Mode). For more information about setting up the target computer, see Preparing a Computer for Manual Driver Deployment and Setting Up Kernel- Mode Debugging over a Network Cable Manually. Configure kernel–mode debugging using a crossover ethernet cable. To enable kernel mode debugging on the target system, perform the following steps.< - On the host system. Open a command prompt on the host system and type ipconfig to determine its IP address.
C: \> ipconfig. Windows IP Configuration. Ethernet adapter Ethernet.
Connection- specific DNS Suffix . Use the IP address of the host system you recorded instead of the one shown in the sample output. C: \> ping 1. 69. Pinging 1. 69. 1. Reply from 1. 69.
TTL=2. 55. Reply from 1. TTL=2. 55. Reply from 1. TTL=2. 55. Reply from 1. TTL=2. 55. Ping statistics for 1. Packets: Sent = 4, Received = 4, Lost = 0 (0% loss). Approximate round trip times in milli- seconds. Minimum = 0ms, Maximum = 1ms, Average = 0ms.
Enable kernel mode debugging on the target system by completing the following steps. On the target computer, open a Command Prompt window as Administrator.
Enter this command to enable debugging. C: \> bcdedit /set . Use the IP address of the host system that you recorded earlier, not the one shown.
C: \> bcdedit /dbgsettings net hostip: 1. Warning To increase the security of the connection and decrease the risk of the random client debugger connection requests, consider using an auto generated random key. For more information, see Setting Up Kernel- Mode Debugging over a Network Cable Manually. Type this command to confirm that the dbgsettings they are set properly.
C: \> bcdedit /dbgsettings. NET. hostip 1. Yes. The operation completed successfully. Change to the Win. Dbg. exe directory.
Glad to hear it works for you! It’s a nasty problem We already have the fix and it will be in Vista SP1 / LHS next year, thats all I can say right now its. If the driver for the REAL ICE, ICD2 or ICD3 is not automatically installed, follow these steps to install them manually. The process is similar for Windows XP and. Alternatively, you can also modify breakpoints by clicking edit > breakpoints in WinDbg. Note that the breakpoint dialog box only works with existing breakpoints.
We will use the x. Win. Dbg. exe from the Windows Driver Kit (WDK) that was installed as part of the Windows kit installation. C: \> Cd C: \Program Files(x.
Windows Kits\1. 0\Debuggers\x. Launch Win. Dbg with remote user debug using the following command. The value for the key and port match what we set earlier using BCDEdit on the target.

The Debugger Command window is split into two panes. You type commands in the smaller pane (the command entry pane) at the bottom of the window and view the command output in the larger pane at the top of the window. In the command entry pane, use the up arrow and down arrow keys to scroll through the command history. When a command appears, you can edit it or press ENTER to run the command.

It may take a bit of time for the target system to respond. Type the following command to enable DML in the Debugger Command window. To become familiar with Win. Dbg operation, the KMDF Template . With the source code available, it will also be easier to understand the information that is displayed in Win. Dbg. In addition, this sample is used to illustrate how you can single step through native kernel mode code.

Right- click Windows- driver- samples- master. Extract All. Specify a new folder, or browse to an existing one that will store the extracted files. For example, you could specify C: \Driver.
Samples\ as the new folder into which the files are extracted. After the files are extracted, navigate to the following subfolder. C: \Driver. Samples\general\echo\kmdf.
Open the driver solution in Visual Studio. In Microsoft Visual Studio, click File > Open > Project/Solution.. Double- click the kmdfecho solution file to open it.
In Visual Studio, locate the Solution Explorer. Make sure that the configuration and platform settings are the same for the three projects.
By default, the configuration is set to . If you make any configuration and/or platform changes for one project, you must make the same changes for the remaining three projects. Set the runtime library. Set the runtime library - Change Runtime Library from DLL version to non DLL version. Without this setting, you have to install the MSVC runtime to the target computer separately. Check driver signing. Open the echo driver’s property page and make sure Driver Signing > Sign Mode is set to “Test Sign”.
This is required because Windows requires that drivers are signed. Build the sample using Visual Studio. In Visual Studio, click Build > Build Solution. If all goes well, the build windows should display a message indicating that the build for all three projects succeeded.
Locate the built driver files. In File Explorer, navigate to the folder that contains the extracted files for the sample. For example, you would navigate to C: \Driver. Samples\general\echo\kmdf, if that's the folder you specified earlier. Within that folder, the location of the compiled driver files varies depending on the configuration and platform settings that you selected in the Configuration Manager. For example, if you left the default settings unchanged, then the compiled driver files will be saved to a folder named \x. Debug for a 6. 4 bit, debug build.
Navigate to the folder that contains the built files for the Autosync driver: C: \Driver. Samples\general\echo\kmdf\driver\Auto. Sync\x. 64\Debug. The folder should contain these files: File. Description. Echo. The driver file. Echo. An information (INF) file that contains information needed to install the driver.
In addition, the echoapp. C: \\Driver. Samples\\general\\echo\\kmdf\\exe\\x. Debug*. . Typically, this is a separate computer from the computer on which you develop and build the driver package. The computer where you develop and build the driver is called the host computer. The process of moving the driver package to the target computer and installing the driver is called deploying the driver. You can deploy the sample echo driver, automatically or manually.
Before you manually deploy a driver, you must prepare the target computer by turning on test signing. You also need to locate the Dev. Con tool in your WDK installation. After that you’re ready to run the built driver sample. To install the driver on the target system, perform the following steps. Enable test signed drivers.
Enable the ability to run test signed drivers: a. Open Windows Settings. In Update and Security, select Recovery. Under Advanced startup, click Restart Now.
When the PC reboots, select Startup options. Select Disable driver signature enforcement by pressing the F7 key. Reboot the target computer. For example, look in the following folder: C: \Program Files (x. Windows Kits\1. 0.
Tools\x. 64\devcon. Create a folder on the target for the built driver package (for example, C: \Echo.
