Read and Write to DDR in Zed Board

Hi, i want to write minimum 256 MB or more to DDR memory of Zed Board. Total size of DDR is 512 MB. And then want to read all the data which i have wrote in memory. I am able to write 64 bytes of data in DDR but not able to write more than that. To write in DDR I am using Axi_dma on PL side.

And one more question i want to ask do i have to enable the READ CHANNEL of Axi_dma to read from DDR???

Regards

Jeff Johnson has a really good tutorial on using the AXI_DMA in Vivado that might be helpful:
