Hi all

 

I want to expand SDMA's script function.

 

Q1.
It seems that NXP provides an assembler for creating SDMA sript, is it available ?
If possible, please tell me the origin url.

The following URL teach me NXP provides a assembler for creating SDMA sript.

Q2.
It seems to be a mechanism to expand binary data converted script into machine language into RAM under SDMA module using channel 0.
What method is recommended for making binary?

 

Is there a way to add the machine language output from the assembler using Hex editor ?

 

According to the following PDF, it can only for i.MX6.

Q3.
Is there sample code to run SDMA using my own SDMA script ?


Q4.
Furthermore, do you have sample code for 2DMA and 3D DMA ?
