Let's start from some basics:

I suppose You use Stream-to-Memory SGDMA?

The sink interface is connected to the FIFO?

How do You debug Your SGDMA? E.g. I've placed all of the SGDMA transfers to on-chip memory, which had memory monitoring option enabled. That helped a lot.

Also, do You use SCFIFO or DCFIFO?

Yes, I use stream to memory SGDMA, and the sink interace is connected to SCFIFO (MM to stream).

I debug my SGDMA bia terminal window, it was sufficient here.
