PXie 8301 Thunderbolt Issue

[DJL026]

I have a new Dell Precision 7750 Laptop that will not properly enumerate the cards in a PXIe-1062Q Chassis via Thunderbolt.    The Chassis and cards function when connected to a two year old Dell Latitude 7490.

The Chassis is detected fine without any cards inserted.

When the Cards are inserted the SMBbus Controller (Chassis)  has issues.  

As one might expect NI Max is a mess as well

I have seen some reports of similar issues but no solutions.   It seems to be a driver issue with new Thunderbolt Hardware / Security?

Hi,

Could you please post a screenshot showing the error code associated with the SMBus Yellow Bang in device manager?  It should be on the first page of the property sheet.

Hi, 

I have been experiencing the same issue, with the same error, but on a different brand of laptop. 

It seems that the issue is not due to the card being present in the chassis but rather the driver of the board. 

In other words, as long as the non-express cards have no driver installed, the system will work just fine, no matter if they're present or not.

I also tried this on an older laptop and it seems to work just fine. 

I noticed that all the people who seem to have this issue use machines equipped with the newer Titan Ridge 7000 Series Thunderbolt 3 controller

I found a similar case that appears to have been solved by the MXIe BIOS Compatibility Software.  Please try that.  If it still doesn't work, check the Windows Event Log for messages from nipxirfk and nipximxk and post anything you find.  This may help identify more details about the problem.

This did the trick.   Thanks!

I'm not by the system, so I can't try this until next week. But I saw this:

Does that mean my customer needs to have a working LabVIEW installation to solve the issue of the shaky Thunderbolt solution, if it happens to them after I've delivered the system?

[jonnycodesalot]

I think you can ignore that.  It's probably something that gets applied to driver documentation by default, to make sure that the driver installer knows what programming environments it should install API support for.  But MXI-Express BIOS Compatibility does not support any APIs, so it would be irrelevant here.

@DJL026

Did the BIOS Compatibility tool actually solve your issue? 8301 isn't listed among the supported Hardware for that tool.

Hello,

I am experiencing the same issue. When i use PXie modules there are no issues but when using PXI modules issue shows up
