compile fdtdump.c in PetaLinux

y_okada

In order to see the device tree information from .dtb file, I would like to use fdtdump command.

My Environment: CentOS 6.5 (64bit)

I found that there is a file named "fdtdump.c" in Petalinux under petalinux-v2014.2-final/components/linux-kernel/xlnx-3.14/scripts/dtc.

However, when I try to compile the fdtdump.c, I need to know various include directories. And I am not sucessful in compiling it.

How can I build fdtdump from PetaLinux source?

    To compile and include applications in a PetaLinux image, use the petalinux-create command to establish a new application directory.  Execute the following command from within a PetaLinux project:
     
    petalinux-create -t apps -n myapp - - enable
     
    This will create a default "hello world" application in the components/apps/myapp directory.   You can then replace the source files with existing ones (or create new ones on your own), and edit the Makefile to perform the compilation with the files added.   Details of the compilation process can be found in the build/build.log file within your Petalinux project.
     
    For building a library, there is a similar command:
     
    petalinux-create -t libs -n libname --enable
     
    This creates a default library build directory in components/libs/libname, which you can alter and compile as you do with the application code.
     
    To include compiled applications and/or libraries in the rootfs, you need to configure the RFS to include the new components.  The toolchain will automatically update the Kconfig to add entries for the new components in the menuconfig tree, so you can run:
     
    petalinux-config -c rootfs
     
    and select the new applications/libraries you have created.
     
    See the README files within the new application/library directories for additional details.

    Dear Ron

    Thank you very much for your reply.

    I did not know how to create library.

    I still do not know how to compile fdtdump.c related to the library or application template you showed me. I will search for this.
