Windows IoTcore, iMX6Q/DL SabreSD: How to load a driver dynamically?

   I have .sys file in C:\windows\system32\drivers and C:\windows\system32\drivers\FileRepository\imxTestDriver folder. But when checked the list of drivers using WinDbg(lm command), I do not see it there. Is there a way to load it dynamically? 

  Windows 10 IoTcore installed in iMX6Q.

  PS: There are some WPP trace logs in the .sys i want to install.

Hi,
Have you tried to build the driver cab file and install it on the device

Hi,
Yes. I did build a driver cab file and install it. Everything went out as said in the link you mentioned. But when I use WinDbg (lm command) I do not see the driver in the list of loaded drivers.

Thanks.

Hi,

>But when I use WinDbg (lm command) I do not see the driver in the list of loaded drivers.

It seems that you want to verify whether the driver has been successfully installed through WinDbg. Have you run the command devcon status * to show the status of connected devices? This command will show the running drivers.

I suggest adding a tag about Windows driver to this question. I am not familiar with this.

Hi,
I did try devcon status *. I do have a problem.

The device has the following problem: 31

I've added the windows-driver tag. Hoping for the best.
