Hi,all. i used a custom board based sama5d3-xplained and run ucosii. i faced a program : i start dma to transmit data from i2s port to ram. i can start dma correctly, but don't know how to stop it. Can someone give me some advice? Thanks!
Thank you very much！i read the datasheet again according what you said，and compared the procedure in the datasheet with the atmel's ASF lib,and found a wapped interface "DMAD_StopTransfer" implemented it already.Thanks again!
