I'm developing the pci device driver on i.MX6Q.
The pci device doesn't have a DMA Controller.
So, I'd like to use SDMA in i.MX6Q.
What I want is to transfer memory to PCI space.
I don't know which script to use, though I read the i.MX6 reference manual.
Then I tried to use "Memory To Memory" script.
The execution was succeeded, but the data were not transferred at all to PCI space.
Can I use SDMA for transferring memory to PCI space?
What script is suitable for in this case?
