Hi,
I am using Windows XP build environment to build the driver. Do you have
any idea how we generate a map file through this. I am using "build -cZ"
command to generate the sys file, but there is no map file generated
with this.

Thanks,
Nitin

Hi Nitin,

I think it is still a problem about your pdb file
path. there is an alternative way to tell what
function it is. You can open your map file, which is
also generated during your sys compilation. Use 0x1b35
minus your map file's offset, which can be found at
the beginning of your map file (eg, 0x1000). Then
result value, say 0x0b35, will be the address that you
search in your map file. Every function contains an
address in the map file, which is its starting point.
And its interval is from this starting point to the
beginning of next function. Find that function whose
interval contains this result value. that's it.

Hi Mat,
Thanks for the reply. I did as suggested by you but I
am still not
getting the function name in the stack trace.
Following is the stack
trace given by the debugger. I used "kd -y SymbolPath
-i ImagePath -z
DumpFileName" command for this.

STACK_TEXT:
WARNING: Stack unwind information not available.
Following frames may be
wrong.

Nitin,

You need to have compiled your driver with "debug
information" and you
also
need the symbols file (.pdb) for that binary, which is
generated by the
compiler.  Place your symbols file in the symbols path
of WinDbg and
then
open the crash dump.  You should then see the name of
your functions and
variables.

Mat

Subject: [wdmaudiodev] How to analyze memory dump

Hi,
I have written a driver for a PCI device. Sometimes it
crashes and I
want to debug it. I want to analyze the memory dump
file that is created
at the time of crash on some other machine. I could
only see the bug
check code and stack traces (only function addresses).
How can I see the
function name and source file name which caused the
crash as we see when
we have the debugger hooked up.
For some reasons I can not hook up the debugger with
the machine on
which the driver is installed. So I have the memory
dump file and I want
to know the cause of crash.
Can anybody help me?

Thanks,
Nitin
