McASP EDMA issue

Sir, 

My issue is related to McASP EDMA configuration. As per my requirement the slot size is 16bit , so I have configured EDMA element size for 4byte and data is incremented for 2byte.

I could hear in the loopback test, but when looking into my ping-pong buffers I can see that the 0th location of my transmitpong and receivepong occupies the same data even if i'm writing intentionally 0 to my transmit pong buffer.
