|
|
Hi,
My OS is win10, and I use Microsoft's official Dbgview.exe
I can't get DbgPrint kernel message like from UltimapDrvr.c
Code: | DbgPrint("Ultimap2 driver loading...\n"); |
Btw, I have no idea how to properly run/unload a .sys file. I have tried devcon.exe, but it fail to install driver.
Code: |
>.\devcon.exe install .\KMDFDriver2.inf Root\KMDFDriver2
devcon.exe failed.
|
Please help me, I want to dev some kernel level driver stuffs.
Thanks.

To get more info on the driver failing to load, look at the log file here:
Code: | %windir%\inf\setupapi.dev.log |
The most common case is going to be the driver isn't signed and your OS is not set to load unsigned drivers.

Thanks, now it works only in x64 devcon.exe and install x64 driver.
And Dbgview.exe shows the x64 driver messages fine.
