It has 3-port Adaptec 4300D add on 1394 card with 3 ports. It shows up as NEC OHCI complaint IEEE 1394 Host controller with yellow bang. But has driver loaded for it in device manager (1394bus.sys, ohci1394.sys. It shows up with yellow bang on other machien also. but works well as windbg target etc) My host is XP/32, it has latest windbg installed and all the 1394 controller stuff set properly (It connect to other tragets well. Those targets have intergarted 1394 ports). I am not able to connect to this target. Another developer with the same add-on card is able to connect to it etc. >> My host says this is windbg " Microsoft (R) Windows Debugger Version 6.10.0003.233 X86 Copyright (c) Microsoft Corporation.

The session goes well, but sometimes after 15-20 minutes the target freezes (like a break point was hit), but WinDbg reports that the debuggee is running and it can not take commands. Also, when I attempt to break into the target (ctrl + break) I am told that I can't communicate with the target: Wrote 0 failed to write of 1 bytes of the breakin packet. Failed to write breakin packet to target. HRESULT 0x80004005 WARNING: The HOST cannot communicate with the TARGET! If I am quick to catch the moment, the first errors are different: Win32 error 0n23 and Win32 error 0n121. I looked around for this error, but I could not find something related to WinDbg. The only way I can resume my session is to shut down the target by pressing it's power button. At first I thought this has something to do with the target entering stand by, but I modified the power options so it should never enter in a sleep state and I started to actively use it. I thought this was my driver's fault (although it just iterates through some LIST_ENTRYs and displays some addresses with DbgPrint) so I restarted the target and never loaded my driver. I noticed that right before this happens the target display goes black for a moment. Any place where I should start looking? windows windbg share|improve this question asked Nov 3 '14 at 12:42 user3002428 928 Which version of WinDbg (6.2.9200 / 6.3.9600)? This sounds like kernel debugging. IEEE1394 or other setup? Please give more details. –Thomas Weller Nov 13 '14 at 21:26 WinDbg 7600.16385, debugging over 1934. Lately it stopped happening. I tried to pinpoint it to something in my driver, but nothing came out. Maybe it

Join them; it only takes a minute: Sign up Unable to debug the kernel driver using Serial cable up vote 0 down vote favorite I am new to driver stuff. I have tried to debug the kernel driver using serial COM port without success. Could someone show me proper direction how to fix the problem? I am seeing the following messages on kd console. ERROR: DavReadRegistryValues/RegQueryValueExW(4). WStatus = 127 ERROR: DavReadRegistryValues/RegQueryValueExW(5). WStatus = 127 ERROR: DavReadRegistryValues/RegQueryValueExW(6). WStatus = 127 At this time, I pressed Ctl^D and kd console and I am seeing READ: Timeout. READ: Wait for type 7 packet READ: Timeout. READ: Wait for type 7 packet READ: Timeout. EDIT: The problem is fixed with WinDbg. I changed the baud rate to 115200 and inserted break (Ctr ^ Break) before Target system completely boots up. I am able to debug the code now. If I insert break after the target system completely boots up then I am unable to debug. I don't know exact reason for it but Happy with current situation. Here are the things I have done
1) Prepared Target system for debug mode by editing the boot.ini file. Added “/debugport=com1 /baudrate=57600” to boot.ini 2) On Host system, started kd.exe and seeing the following output C:\Program Files\Debugging Tools for Windows>kd.exe -k com:port=1,baud=57600 Microsoft (R) Windows Debugger Version 6.6.0007.5 Copyright (c) Microsoft Corporation. All rights reserved. Opened \\.\com1 Waiting to reconnect... 3) Rebooted Target system, system boots slowly than normal boot and I am seeing some messages <> on Host system console 4) At this time, If I press Ctl-C on KD console then Target system freezes (hangs) and proceeds if I enter "g" at kd prompt. This means that Target system is going to debug mode 5) However After some time I am seeing the following message on the host machine console ERROR: DavReadRegistryValues/RegQueryValueExW(4).
