We are planning access I.MX8M plus (MASTER) DMA over QSPI interface with FPGA as a Slave. 

we are unable to find adequate information to access the DMA. Can you please share the procedure/algorithm to access DMA i.MX8M plus chip.

Also provide if any reference is available for i.MX8M plus DMA access.

I look Forward to Hearing Back.

Thanks in advance...!!!

Hi mk:

 

QSPI driver is described in section 3.5 of Linux Manual.
