EDMA using CSL to EDMA using SYS/BIOS

Hi Zakaria,

Thanks for your post.

There are EDMA based SYS/BIOS examples under EDMA_LLD of MCSDK 2.0 folder which has test/demo code to demonstrate the EDMA3 driver functionality and it does EDMA3 mem-to-mem data copy testcase,  EDMA3 ping-pong buffers based data copy test case on BIOS6. The examples can be found in the path below:

~\ti\mcsdk_2_01_02_06\edma3_lld_02_11_05_02\examples\edma3_driver\evm6678\sample_app

To program the EDMA3 using LLD,

Likewise, you also have CSL based EDMA examples at the below loaction:

~\ti\mcsdk_2_01_02_06\pdk_C6678_1_1_2_6\packages\ti\csl\example\edma\edma_test.c

The above is the  EDMA example test code uses the EDMA CSL functional layer for the c6678 device.  You can build it for other targets (C6670, C6657 ) too through copying the above EDMA test source code into a new empty CCS project and link the functional CSL EDMA library (file name : ti.csl.ae66 ) by adding the directory to the library search path to the project properties->File Search Path. Then you can build this EDMA example in CCS and run without any issues.
