Thanks Colvin for the information . I have gone through the tutorial but the board is not getting detected . I have followed the link alongwith yours provided info.
But after using MATLAB linux into the SD card and and configuring as per Zybo definition . we need to use xilinx HDL coder hardware support package which is explicitly written for Z7020 . So,the baord is not getting after generating bit-stream.
see the stage by errors here . I have resolved some but still the final problem persists . Board is not getting detected.
Can you please suggest some way out.
