Hello everyone
I tried and search but cannot find the solution of my problem.
I tried alot (even i looked many threads)
I recompile by myself kernal using (implementing linux on the zynq guide) and successfully build uImage/zImage after that the system hang.

Starting kernel ...

I tried to find the solution (search many times) but can't find the solution yet.

May be some one help here

    When Linux hangs this early in the kernel startup, it is usually an issue in the device tree that is telling Linux to go and probe a specific piece of hardware that doesn't exist, or doesn't exist at the address or with the parameters specified.  Or it could be that the kernel has been built using a BSP for the wrong platform, but that is less likely.

    If you are new to Linux, I recommend starting with an existing PetaLinux BSP for Zedboard.   There are pre-built binaries in the BSPs to let you test the operation of your board, and the project created from the BSP can easily be rebuilt to ensure you are starting from a known good point.  Then you can make incremental changes to your design with a good chance of success.

    hello again
    The problem has been solved.
    I was not making link between u-boot and uImage
    for this i used the following command
      U-boot-xlnx/tools$ export PATH=$PATH:$PWD
    and then go back to the xilinx-xlnx directory and then recompile the kernal.
    hopefully it will help the others
