DMA busy

I use a DMA to tranfer 1800 bytes. The DMA work. I need to make again the tranfert soon after the first transfer, but it took a long time between the 2 transferL. In fact the DMA is always BUSY....

I have read this topic and it's not the same error because,

LINE_SIZE=1800,

If I select burst mode or not, nothing change.

In sopc builder I put the DMA length register to 11 bits (->2047 bytes).
