RTOS/TMS320C6678: EDMA3 does not copy and runs slowly

Part Number: TMS320C6678

Tool/software: TI-RTOS

I made a small project using EDMA3_LLD. The project copies data from DDR3 memory to L2RAM memory. However, copying is not performed - the array in the memory L2SRAM is empty. Also, the test shows that the time to copy an array of 128 elements is about 2000 cycles! I use CCS 7.3 and EDMA LLD v.2.12.5.

What could be the problem?

Why such a low copy speed?
