Axi DMA always busy

[tiago0297]

Hi, 

 

I'm doing a project that uses AXI DMA. I already done my Ip Core, my Block Design e and my SDK code. The problem is that when my program reaches while(XAxiDma_Busy(&axiDma, XAXIDMA_DMA_TO_DEVICE)) it gets stuck. I'm using a Zedboard and Vivado 2017.4.

 

I did a search, found out that it's a very popular problem, but I had no success solving it, so I'm posting here trying to get more help. I'm attaching my sources.

 

Thank you

Hi @tiago0297,

I do not have a lot of experience with using the DMA. With that in mind i found a non-digilent tutorial that uses the DMA and the Zynq processor here.  Here are some DMA examples provided by Xilinx as well.

thank you,

Jon
