Honored ContributorDMA 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....

have you tried simulating this software in modelsim? --- Quote End --- thst's rigth i want to read from the SDRAM to the FIFO interface which i took on the forum in "post your own IP". I write, like you say, 450 words. I'm writting on the fifo in stream mode. I don't have modelsim.
