** Maybe so, but the Qsys flow doesn't support a streaming interface to the pcie. It seems like a lot of work to put the pci express block outside of qsys and take care of flow control (credit processing must be done by hand) just to do dma, especially when my transactions are always the same length.

Where is it described - how to put the PCI Express block outside of Qsys, take care of flow control and how credit processing is to be done by hand?

I've since discovered that chapter 1 'Introduction' to the Embedded Periperals IP User Guide says that this core is not 'supported by QSYS'. This is not mentioned in the chapter describing the DMA controller itself. This should be translated to mean: It doesn't work. I hope this post can prevent someone else from wasting time with this.

That is strange because in Chapter 17 ( Qsys Example ) from IP Compiler for PCI Express User Guide ( May 2011 ) DMA controller IP core is used.
