tms320c6657 edma3 problem

Hi,

I have a problem with dma in tmdxevm6657le kit.

I need to use mcbsp to communicate with other device (receiving and sending audio samples). I have configurated mcbsp with dma support and after collecting 8 32bit samples interrupt is generated. Everything work great until i try to read received data from input buffer, after reading data from it new samples aren't placed in int, dma is still working, param sets are changing but new data is not appearing in input buffer. My project is added in attachment.
