PCI in uClinux

You have to update altera pci core config page 4, avalon config,

change the pci base address of 32 bits memory page, to the value of avalon bus address assigned in sopc builder. ie, 86100000 in your case .

you should also update the io page mapping.

We want to use the same address mapping in both pci space and avalon space.

config space , pci base 0 , == avalon 86000000

mem space, pci base 86100000, == avalon 86100000

unused space?

io space, pci base 86300000, == avalon 86300000
