Hi,

I tried all possible options and was able to narrow down on the problem. If I enable burst transfers in SOPC, I am getting this problem and if I don't enable it is working fine. Can you explain this? Why does the DMA write only a byte of the word if the burst transfer is enable?

Hi,

@gangireddy

what did you mean with 'enabling burst transfer' and 'disabling burst transfer'? How did you control it? And what was the DMA control register value for both conditions?

Would you post your code here? Now I have problem with DMA but as Rx channel. I have been debugging my DMA for several weeks, but it can't work.... :( I'm sure that it should be easy but I really don't know what the problem with my code. So I hope that you kindly post your code here. Next post, I'll post my code here.
