SDMA memory to memory Stride support

Hi,

I want to display two video buffer in one display.

So I need to copy both buffer in to the frame buffer.

Is it possible to use SDMA with memory to memory copy using stride support?

Is there any alternative solutions ?

Thanks

Saurabh

Hi Saurabh

existing SDMA scripts described in Appendix A SDMA Scripts IMX6DQRM

do not support stride, so one will have to write own custom

SDMA script for that, link below may be useful.

Best regards
