    I did and it is working fine. I´m not sure if it is able to handle DMA transfers, I haven´t tested this since yet. The Core itself works properly good.

    Hi again,

    I only tried it as a Slave Bridge under Windows, so I can´t help you out here. It just works as normal PCI device. Like I said I haven´t tried the DMA or burst transfers on it.

    Hi, i am trying to use OpenCores PCI Bridge but i have some doubts.

    Whats exactly is the Image Address and how it works?

    When i am receiving some information on PCI Target, how can i define the

    WishBone Slave that is being addressed?

    When i am sending some information with a WishBone Master to the Bridge

    Slave, how can i define to which PCI on the BUS i am addressing?

    Thank you!
