Unable to apply 32MB Ramdisk patch to U-boot

Former Member

Hello all,
  I've been going through the Implementing Linux on the Zynq-7000 SoC speedway course but ran into a road block.  I completed all the labs up to lab1_2 #11 where you copy over the given patch file and apply it with the following command.

git apply 0001-Xilinx-ARM-Experimental-32MB-Ramdisk-on-ZedBoard.patch

I get the following error.

[blw184@localhost u-boot-xlnx]$ git apply 0001-Xilinx-ARM-Experimental-32MB-Ramdisk-on-ZedBoard.patch
error: patch failed: include/configs/zynq_zed.h:38
error: include/configs/zynq_zed.h: patch does not apply

Am I doing something wrong?

Thank you,
Brandon

    Hi

    If you type "git branch" into the terminal what comes up?  Xilinx have changed the way the zynq config files work so you may need to checkout an older branch.

    Thanks for the reply m.russell!

    [blw184@localhost u-boot-xlnx]$ git branch
      master
    * xilinx-14.2-build1-trd

    I think that's the correct build?

    I also ran into an similar problem with patching the linux-xlnx.
     
    [blw184@localhost ~]$ cd linux-xlnx/
    [blw184@localhost linux-xlnx]$ git apply 0001-Xilinx-ARM-Kernel-32MB-RAM-disk-on-ZedBoard.patch
    warning: arch/arm/configs/xilinx_zynq_defconfig has type 100755, expected 100644

    Thanks,
    Brandon

    With regards to the similar problem with patching the linux-xlnx.  The tutorial did say "Ignore any warnings about file permissions or types."  So I'm assuming that error is OK.

    Yep, that's the right one.  I just ran through that part of the speedway and it worked OK for me.  Try to clone the repository again, check out xilinx-14.2-build1-trd, and apply the patch on a clean version.

    The warning with the Linux patch isn't a problem.

    Which steps did you exactly perform/what do you mean with "clean version"?
    I have the same problem with the patch and I get the same message after "git branch" but when I try the "make" command I get this error message:

    Did you have the same problem or is this something different?

    Hi

    It looks like you've set the CROSS_COMPILE variable to arm-linux-, it should be arm-xilinx-linux-gnueabi-.  The command to change this is:

    export CROSS_COMPILE=arm-xilinx-linux-gnueabi-

    By a clean version I mean one which has had "make distclean" run on it, this removes any config or build files which may cause problems.

    My CROSS_COMPILE variable is set to arm-xilinx-linux-gnuabi, this is my .bash_profile without any changes:
    ----------------------------------------------------
    # .bash_profile

    # Get the aliases and functions
    if [ -f ~/.bashrc ]; then
            . ~/.bashrc
    fi

    # User specific environment and startup programs

    PATH=$PATH:$HOME/bin

    export PATH
    export CROSS COMPILE=arm-xilinx-linux-gnueabi-

    # Do NOT modify these lines; they are used to uninstall.
    PATH="/home/training/CodeSourcery/Sourcery_CodeBench_Lite_for_Xilinx_GNU_Linux/bin:${PATH}"

    ".bash_profile" 20L, 653C                                     1,1           All
    ----------------------------------------------------
    I have still the problem with the patch described in the first commend, even when I clone the u-boot-xlnx directory again and make a distclean, could it be that this is the source of all my problems?

    The error with the patch would not cause the make errors, it would just build the un-patched u-boot file.  If you type "echo $CROSS_COMPILE" and "echo $PATH" into the bash terminal what comes up?

    If all else fails, the patch file is human readable.  You can open it using a text editor and apply the changes yourself, it's only a few lines.

    It works now, I just installed linux again and repeated the complete process but it's really confusing why it have not worked for the first time...

    Thank you for your help

    I did exactly what you suggested and this time it worked.
    Thank you so much.
