There are two different libraries for EDMA3 programming. One is more for device-drivers, EDMA3 LLD:

and the other is more for algorithms, ACPY3:

They work together to allocate DMA resources.

You can download them both from here:

The Latest EDMA3 LLD package that has support for DM6437 is available for download at

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/psp/edma3_lld/edma3-lld-bios5/01_11_01_04/index_FDS.html

Please go through the sample application provided in the C:\Program Files\Texas Instruments\edma3_lld_01_11_01_04\examples\edma3_driver\evmDM6437 folder after installing the package.
