the problem of 8431/4 borad on PXI bus

[yjsaxf]

Hello,

when I connect the PXI-8431/4 board to the PXI bus in QNX system, I find that there is only one "PCI Mem Address" record.

But the other boards(e.g. NI PXI-6602,NI PXI-6250) have two "PCI Mem Address".

you can see the following detail trace:

Class          = Unknown (Unknown)
Vendor ID      = 1093h, National Instruments
Device ID      = 70b9h, Unknown Unknown
PCI index      = 0h
Class Codes    = ff0000h
Revision ID    = 0h
Bus number     = 20
Device number  = 13
Function num   = 0
Status Reg     = 280h
Command Reg    = 117h
Header type    = 0h Single-function
BIST           = 0h Build-in-self-test not supported
Latency Timer  = 20h
Cache Line Size= 10h un-cacheable
PCI Mem Address = f6406000h 32bit length 4096 enabled    //PXI-6250
PCI Mem Address = f6405000h 32bit length 4096 enabled
Max Lat        = 0ns
Min Gnt        = 0ns
PCI Int Pin    = INT A
Interrupt line = 10
CPU Interrupt  = ah

Class          = Communication (Other)

Device ID      = 70deh, Unknown Unknown
PCI index      = 0h

Latency Timer  = 20h
Cache Line Size= 10h un-cacheable
PCI Mem Address = f6407000h 32bit length 4096 enabled   //PXI-8431
Subsystem Vendor ID = 1093h
Subsystem ID        = 70deh
Max Lat        = 0ns
Min Gnt        = 0ns
PCI Int Pin    = INT A
Interrupt line = 10
CPU Interrupt  = ah

Is there any problem?

Because there is only one Mem Address in QNX system, the interface function acquireBoard() will be  returned by Error: bar1 map: invalid argument.

Therefore, it can not be initialled in QNX system.

Maybe it just gets two memory card.
