Thanks for that, I did not notice that in the spec. I am currently using 64 bit format unconditionally and this must be what is going wrong.
Thank you so much for that.

Subject: Re: PCIe device driver question
How are you formatting the addresses in the TLP? The PCI Express spec
says that for addresses below 4GB the 32-bit addressing format must be
used (you can't use the 64-bit format unconditionally). It could be that
is what is making the chipset unhappy.
