    The dumpimage is able to extract components contained in a FIT image:

    $ ./dumpimage -T flat_dt -i CONTAINER.ITB -p INDEX FILE

    The CONTAINER.ITB is a regular FIT container file. The INDEX is the poisition
    of the sub-image to be retrieved, and FILE is the file (path+name) to save the
    extracted sub-image.

    For example, given the following kernel.its to build a kernel.itb:

    /dts-v1/;
    / {
    ...
    images {
    kernel@1 {
    description = "Kernel 2.6.32-34";
    data = /incbin/("/boot/vmlinuz-2.6.32-34-generic");
    type = "kernel";
    arch = "ppc";
    os = "linux";
    compression = "gzip";
    load = ;
    entry = ;
    hash@1 {
    algo = "md5";
    };
    };
    ...
    };
    ...
    };

    The dumpimage can extract the 'kernel@1' node through the following command:

    $ ./dumpimage -T flat_dt -i kernel.itb -p 0 kernel
    Extracted:
    Image 0 (kernel@1)
    Description: Kernel 2.6.32-34
    Created: Wed Oct 22 15:50:26 2014
    Type: Kernel Image
    Compression: gzip compressed
    Data Size: 4040128 Bytes = 3945.44 kB = 3.85 MB
    Architecture: PowerPC
    OS: Linux
    Load Address: 0x00000000
    Entry Point: 0x00000000
    Hash algo: md5
    Hash value: 22352ad39bdc03e2e50f9cc28c1c3652

    Which results in the file 'kernel' being exactly the same as '/boot/vmlinuz-2.6.32-34-generic'.

  • f41f5b7c0   dumpimage: add 'T' option to explicitly set the image type ... Browse Code »

    Some image types, like "KeyStone GP", do not have magic numbers to
    distinguish them from other image types. Thus, the automatic image
    type discovery does not work correctly.

    This patch also fix some integer type mismatches.
