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.

Freescale i.MX SDMA tutorial (part IV)

Best regards
