Hi Caglar, You have to poll on the IPR register. Later to clear the bit in the IPR, you will have to write to the ICR register as IPR is read-only. You can find the details in this document: http://focus.ti.com/lit/ug/sprueq5a/sprueq5a.pdf

Under Linux I use dma callbacks but under u-boot there is no interrupt handlers(AFAIK) so I'm trying to poll EDMA registers. I wonder what is the correct register to poll, I tried different methods but they are not reliable yet.
