AM572x PCIe Interrupt Error

Other Parts Discussed in Thread: XIO2001

Hi Sitara Team,

Could you help me resolve the following issue for my customer:

We are working on connecting Wi-Fi card on PCI-e interface of AM57xx.

We are able to detect the connected devices on PCI-e interface through lspci command, but it gives some error related to pci interrupt.

  Here is a capture with highlighted areas that indicate the problem:

It seems that it has some error related to PCI interrupt registration.

See, if someone can look into this and guide us on what we are missing.

  • Hi Christian Alford,

    What exactly is the PCIE issue facing ?

    Can you share the dts/dtsi file being used. Also it would be helpful if you can share the full dmesg, along with at the time of failure.
  • Feedback from Customer:

     

    On PIC-e, we are able to detect the connected devices via PCI-e. But, the error is related to PCI-e interrupt.

    The error says no irq domain found for pic-e.

    [    0.648979] irq: no irq domain found for /ocp/axi@0/pcie@51000000/interrupt-controller

     

    So, when we try to load any firmware on our PCI-e connected end device, it does not work. Seems like it is due to this irq error.

    Also attached full kernel log and .dts, .dtsi files, which we are using. We are using “sdk- am57xx-evm-03.00.00.04” and linux-kernel 4.4.12

  • Hi, Christian,

    It looks to me that the DTS file has some issues. One obvious one is missing pcie infront of @51800000. Not sure why it complains about the others. They look good to me. I'll go through it again to be sure that I don't miss any.

  • Hi, CHristian,

    Just follow up on this one and has the error in the dts file been fixed and what's the outcome of if?

    Rex

  • Hi Rex,

    Customer is still having issues with their file. Here is the latest response:

    As per the comment on forum, can you verify what is the issue with DTS file?

    Do we need to add anything in DTS file for PCI-e interrupt registration or activation?
