I have debugged drivers on VM (pipe connection) with Windows 7. Now I want to debug a driver in a laptop with Windows 7 (x64) but the WinDbg keeps waiting forever for the connection:
Microsoft (R) Windows Debugger Version 6.7.0005.1 Copyright (c) Microsoft Corporation. All rights reserved.
Opened \.\com1 Waiting to reconnect...
In the target laptop I boot with this BCD entry:
Identificador {current}
device partition=C:
path \windows\system32\winload.exe
description DebugEntry
locale es-ES
inherit {bootloadersettings}
recoverysequence {b3c5a314-b064-11df-ba01-a8d3a819aefa}
recoveryenabled Yes
bootdebug Yes
osdevice partition=C:
systemroot \windows
resumeobject {b3c5a312-b064-11df-ba01-a8d3a819aefa}
nx OptIn
detecthal Yes
debug Yes
The debug settings on target are:
C:\windows\system32>bcdedit /dbgsettings debugtype Serial debugport 1 baudrate 115200
Baudrate is the same in both host and target because I launch the debugger this way:
windbg.exe -k com:port=COM1,baud=115200
The cable works for kernel debugging because I have used it before, in fact when I monitor the COM1 in the target machine I can see the polling messages comming from the WinDbg and even the Control+Break message... but nothing happens.
The serial port, as expected, is enabled in both BIOS settings.
Also, it seems that Windows is not waiting fot the timeout on COM 1 at boot time, it starts normally without a delay...
Any suggestions?
