MCBsp and DMA syncronization problem

Started by m_mo...@yahoo.com October 16, 2011
Dear all
In 5416 DSP processor :
I used MSBSP number 0 and 1 to get CODEC sound data by using DMA channel 4 and 5.

Both DMAs are used to get data from mcbsp ports.
Frame sync and clock signals are input to this DSP processor.
But I have reset problem.
When I reset the board I find that sometimes input data is correct and has no problem but some other times input data is not correct. and something like shift in data can be seen.
I think there should be a synchronization problem.
But I have no idea how to solve it.
Could you please give me some guide or information to overcome it.
