Using DMA transfer data from memory to SATA

[sharpjison]

Hello NXP:

      In kernel space, I need to use DMA to transfer a big data from DDR to SATA .

      This operation is nothing to do with using space and the file system.

       What can I refer to？

Have a nice day!

Thanks !

Hi Sharp

sdma is supported in nxp linux for some modules and described in Chapter 4 Smart

Direct Memory Access (SDMA) API attached Linux Manual. Unfortunately there

is no such support and sdma script for sata. In general one can try to reuse approach

for pcie (IPU used as the bus master(DMA)) from link

i.MX6Q PCIe EP/RC Validation System
