Hello,

Is it possible to use the SDMA to transfers a video surface to the video memory? This would be a X,Y continuous memory to X,Y with stride jump for each line. The SDMA is script capable. What would be the best way to test/try a new script? My package include binary data for script.

Thanks. Guy

Hi Guy

in general this is possible, unfortunately nxp does not support

sdma customization. One can try to use for example
