We are developing a new medical scanning technology that uses a Kirkwood 88F6281 SOC to communicate with fpga boards via a XIO3130 pci bridge.
As part of the that development process we purchased a Marvell OpenRD in order to continue to prototype this work. This was used to interact with a TI XIO3130 evaluation board PCI bridge.
We are finding that the OpenRD fails to recognise the XIO3130EVM when it is plugged into the external PCI-E slot. We have tested a standard NIC in the PCI-E slot and it works fine and passes traffic. We have also tested the XIO3130 evaluation board in a standard x86-64 based PC and we can both see the XIO3130 evaluation board and pass traffic through a NIC plugged into it. We have tested with both the stock Fedora kernel provided with openrd and more recent Debian 2.6.32 and 3.2.0 kernels.
Has anyone any experience of when the XIO3130EVM is not recognised when it is connected to a Kirkwood 88F6281 SOC but does work when it is connected to a x86-64 based device? Any help would be appreciated
