Zedboard MC DMA support

Question

In the Vivado SDK install, there are code examples for using the MC DMA.  I want to get the example xmcdma_polled_example.c working on the Zedboard.  Is there any documentation or FPGA design block diagrams for this?

I modified the example a bit to map the transmit & receive & buffer descriptors to actual Zedboard memory.  Attached.

Thanks,

xmcdma_polled_example.c

Hi Steve,

Unfortunately we haven't worked with Xilinx's MC DMA. Your issue is not board specific, so it falls more on Xilinx side.

I see you've already posted on their forum. Based on the details you gave there we suspect a clock line or reset line is not connected properly.

thanks
