Subject: [oc] PCI card can't work in different motherboard
Hi everyone,i have just finish implementing a Slave PCI into a FPGA on a PCI board.
And this core seems work fine. Work fine means the OS can find the
new hardware component and ask for the driver, also can read / write
data by using WinDriver. But when i plug this card onto another
motherboard which is with on-board lan card. The OS can't discover this
new hardware and the original on-board lan card on this mothercard has
disappeared(it don't show up in the software). However, my core do not
have problem in every motherboard without on-board lan card.
I find it very strange and i don't know why. Is the PCIBIOs on different
motherboard has difference in configurating the device? Or the memory
range i declare in my core has exceed the range that the mother board
can give to my hardware?( i just declare 256 K in my hardware). Or
anything crush in the interrpt?
Is it possible that a PCI card can work in one motherboard but fail in
another one?
Thank you very much and any reply will be appreciated.
Regards,
TOM
