Hi WorkerBee, I think you descript clearly about your issues. For the primary issue, sorry I have no idea about why the result get the mis order currently. So if you could give more information about your DMA configuration,maybe the sysconfig and source code may be helpful. What I want to know is the DMA address configuration and how you update the address after DMA complete. For the another question, I got your point. Please see my last reply. I mean the "DMA complete" is triggered by DMA size decrease to Zero. So if you do not re-configure the DMA size by DL_DMA_setTransferSize() after last DMA complete, it is possible that "DMA complete" occurs again because the DMA size remain as Zero. So I have given you my suggestion of re-configuring DMA address and size in DMA complete interrupt. Best Regards, Pengfei
