I have been successfully using the OpenCore PCI
core in a Spartan-2 200k part. I have been able to access configuration
space directly and through the memory mapped image, I also am able to access
a memory mapped image.
My only problem comes in when I try to add an
additional PCI image that uses an IO mapping, instead of a Memory
mapping.
I get an error message at boot time
saying:
PCI I/O Port Conflict: Bus 00, Device 0F, Function
00
I press escape to continue booting into
Linux. Once the machine has finished booting, the results of lspci -v
are:
00:0f.0 Bridge: Unknown device 2321:0001 (rev
01)
Flags: medium devsel, IRQ 9 Memory at fe000000 (32-bit, non-prefetchable) [disabled] [size=16M] Memory at f7000000 (32-bit, non-prefetchable) [disabled] [size=16M] I/O ports at <unassigned> [disabled] When I don't include the IO space image, region 0
and region 1 are fully functional.
The changes that I make in pci_user_constants.v
over the default crt application version are:
`define PCI_IMAGE2
`define PCI_BA2_MEM_IO 1'b1
Information and/or suggestions are greatly
appreciated.
