NAME
       dumpimage - extract data from U-Boot images

SYNOPSIS

       dumpimage [-T type] [-p position] -o outfile image

       dumpimage -h

       dumpimage -V

DESCRIPTION
       dumpimage lists and extracts data from U-Boot images. If -l is
       specified, dumpimage lists the components in image.  Otherwise,
       dumpimage extracts the component at position to outfile.

OPTIONS
       -h     Print usage information and exit.

       -l     Print the header information for image, including a list of
              components.

       -o outfile
              The file to write the dumped component to.

       -p position
              Specify the position of the component to dump. This should be a
              numeric index, starting at 0. If not specified, the default
              position is 0.

       -T type
              Specify the type of the image. If not specified, the image type
              will be automatically detected. A list of supported image types
              may be printed by running mkimage -T list.

       -V     Print version information and exit.
