Dear all,


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?

 

Best regards,

Hiromichi
