Subject: [pci] PCI card can't work in different motherboard
Hi everyone,i have just finish implementing a Slave PCI on a FPGA board with PCI
interface. 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 the
motherboard which is with on-board lan card. The OS can't discover this
new hardware and the original on-board lan card on the 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. Can anyone give me a hand?
Is it 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 cursh in the interrpt?
Thank you very much and any reply will be appreciated.
Regards,
TOM
