    Hi Cong,

    Thanks for your post.

    In my guess, there could be issue in configuring the EDMA transfer through EMIF.

    There are EDMA CSL examples to perform a simple memory to memory transfer using EDMA and you shall download the C6455 DSK software package in the below link:

    http://c6000.spectrumdigital.com/dsk6455/v2/files/dsk6455_v2.zip

    After you download the package, the EDMA CSL examples shall be found at the below path:

    ~\dsk6455_v2\boards\dsk6455_v2\csl_c6455\example\edma\edma2x_example

    In addition to the above, there are several EDMA examples (interrupt, ping pong buffering etc), in which you shall refer the EDMA configuration for all usecase examples. For more info, you shall refer the C6455 CSL API reference guide & release notes at the below path:

    ~\dsk6455_v2\boards\dsk6455_v2\docs\csl

    Please refer the below C645x EDMA3 controller user guide in which there is a block move example which performs EDMA transfer:

    Thanks & regards,
