    Satish,

      There are numerous examples for different Zynq boards on this site that describe the process of booting Linux from an SD or microSD card.  Since the Zynq PS is part of the hard IP in the APSoC, the instructions are applicable to all Zynq devices.   It is not even necessary to load a bitstream into the PL to boot Linux, which is where most device tree differences are found.  If you are just getting started I would recommend that you try using the PetaLinux BSP for Zedboard, available from the Xilinx Support website, for the version of tools you are working with.  There are a number of PetaLinux support documents that walk you through BSP installation and usage on the same site.

    I am greatful for getting quick response,
    1. I have gone through PDF from xilinx website,
    "Getting started with Embedded Linux-ZEDBoard".pdf
    i have done partions of SD card, following remaining  steps. I a getting errors in booting kernel.

    2.I have downloaded "ZedBoard_OOB_Design.Zip", I am successful in petalinux-build and can emulate in QEMU.
    But when doing the same for ZED board, I am getting issue as
    after downloading boot loader code and

    zynq-uboot> tftpboot /tftpboot/image.ub 0x1000000
    "trying to setup GEM Link"

    and halt here only.

    Can you please provide me any other document through which i can boot peta linux BSP on ZED board.
    sorry, if i am asking basic questions
    Thank you in advance.

    Regards

    I can boot ZED board iwth digilent kerenl and Device tree.
    but when I am doing the same with Petalinux BSP boot,
    it is stopping at
    "starting application at 0x00080000"

    how do we boot Petalinux BSP with SD card.

    I believe problem is with u-boot code env args. means BOOT.BIN file has to change.

    Thanks
