strezh / xpdma Goto Github PK

I'm not sure if this is intended or if I'm missing something, but this line:

https://github.com/strezh/XPDMA/blob/master/driver/xpdma_driver.c#L337

Only looks like it would work when direction is PCI_DMA_FROMDEVICE, and not PCI_DMA_TODEVICE. This is because on this line:

https://github.com/strezh/XPDMA/blob/master/driver/xpdma_driver.c#L346

srcAddr is moved, but translation is done by the PCIe block. Instead, this address should remain constant at AXI_PCIE_DM_ADDR, unless I'm mistaken.

EDIT: It looks like destAddr has the same problem. I'm definitely missing something.

Thanks for sharing ,

I've tried in Vivado 2018.03 ,
by default run generate.sh , there's generation errors.
Could you help me for adapting your works on latest toolkit?

And, if you 're interesting our custom k7 board, for example pci , mail to me : [email protected]
I will thanks to your helps.
