RE: Windows examples failed to start using mellanox card

[Tal Shnaiderman <talshn@nvidia.com>]

Hi Robert,

I'm glad to hear the issue is resolved, but I still want to understand why you get the error print as I'm not able to reproduce it on my side.

Are you using a Virtual Machine or is it a back-to-back setup? Can you also state the WINOF2 FW version you're using?

Thanks,

Tal.
