Shuai,

The EDMA used in TDA2 is no longer in TDA4. You can first try to compile the lib in CCS v9 without EDMA (use cache) to see that the build, link, and run are functional. I will see who can follow up on what new DMA library you can use from the PSDKRA package.

Regards,

Jesse

The DMA on TDA4x is called UDMA. You can reference how it can be used in following folder:

PSDKRA: vision_apps/utils/udma

Jesse
