Resource conflict: PXI 1000B with NI PXI 8106 & NI 8420/2

[Steviooo]

Dear readers,

What:

I am using an embedded controller (PXI 8160) with a rs232-card (NI 8420/2) in a PXI-rack (PXI-1000B).

Problem:

At startup of the rack, i get the message: Resource conflict, PCI in slot 2    /     Bus: 0B , Dev: 0F, Function: 00. F1     / Press F1 to resume or Del to enter Setup.

If i continue after the conflict, i can see the 2 com-ports properly installled in my hardware manager .

After startup, when i look in the systemtab of eventviewer, i find an error. This one is also there when the 8420 is not plugged in.

"Boot-start or system-start drivers failed to load: nvatabus / nvraid" + "Source: service control manager". (see attachement)

What did i try:

If i remove the NI 8420 card, there is no problem.  If i keep the 8420 in the rack but in another slot, the problem stays but at a different slot.

Maybe there is something wrong in the bios settings, though i almost tried every setting including reset/ disable comport of the 8106/ ... .

Swapping the card did not work too.

I tried this 8420 in another rack (without an embedded controller) but there were no conflicts.

Formatting the embedded controller (windows xp and drivers)

I hope somebody can tell me more about this. Thanks in advance.

Hi (again) steven,

Im sorry but I didnt get a chance to look into this further today, and Im away out of the office for the next two working days.

I would recommend (if you have SSP - standard service package with NI UK), to contact us on 01635 523545 - so someone in the team can look into this for you.

Otherwise I will when I return / if you do not get a successful answer!

Kind Regards,

Hey Steven,

This warning is showing that the two or more new Communication Ports of the device are sharing memory address space. This is normal and does not affect the devices functionality as you have verified. There is nothing wrong with the board.

Thanks Wouter,

Can you give me some advice for disabeling the device during startup in the bios? I did not find out how to do it.

Best regards

Hi Steven,

I have the same problem with my PXI-RT System. Did you solve this problem? Unfortunately the answers from NI doesn't solve the problem! ! !

Thanks

If you have a legacy 8420 card of revision A, there is a problem with memory mapping which causes the resource conflicts. If you have a card of revision A, you can send the board in for RMA to upgrade the EEPROM of the card to a higher revision. This is done at no charge. You can check the revision of your card from the part # of the card. You can find it on a small sticker on the board. It is a number containing 6 numbers, followed by one letter, a dash and 2 numbers. The letter actually is the revision of the board. If it reads A, you can call your local NI branch to get the card upgraded.
