Hi folks,
I want to write data/file to Sdcard present in Zedboard. I am able to write data to DRAM. How Can i Read from DRAM and write that particular data to SDCARD?
I have searched but not able to find any good tutorial for this.

You don't have to do the complete lab of data logging using the OLED screen. Just create a Zynq Processing System ,do procedure B (Enable SD0 Host Controller on PS ) exactly as explained in the tutorial(cuz the default settings of Vivado r wrong). Then procedure C and D. However, in procedure E you need to create your own application. Read the FatFs API sections to be able to use it.

I have another question. 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???

I have posted a new forum here (http://zedboard.org/content/read-and-write-ddr-zed-board) but no one answered So Please help Sir.

Regards
