    Atom E3800 inbound PCI write to memory

    JTH Community Member

      Is it possible to map Atom E3800 (E3825) system memory to PCI memory space?  I don't see anything in the Datasheet to support this.

       

      I have a peripheral card on the PCI side of a PCI Express to PCI bridge that will initiate DMA transfers to PCI.  I was hoping to initialize a BAR and remap so that these DMA writes target E3825 RAM.

          Hello, JTH :

           

          Thank you for contacting Intel Embedded Community.

           

          In order to better understand your consultation, could you please tell us the document number and version of the datasheet that you have mentioned? By the way, could you please tell us if the design has been developed by you or a third party company? In case that it is a third party design, could you please give us all the information related to it?

           

          Thanks in advance for your clarification.

           

          Best regards,
