Hi All,
I am trying to compile an overlay and use it for study purpose but I am not
able to compile an overlay. For example I took an example device tree
overlay from derek molloy blog
git clone git://github.com/derekmolloy/boneDeviceTree.git
and now I have a directory with a name overlay. In that a script *build* is
there that have the compilation command for this overlay. this is the
command inside build
*#!/bin/bash
echo "Compiling the overlay from .dts to .dtbo"
dtc -O dtb -o DM-GPIO-Test-00A0.dtbo -b 0 -@ DM-GPIO-Test.dts*
*DM-GPIO-Test.dts* file is the source overlay file and
*DM-GPIO-Test-00A0.dtbo* is the output.
Now if I run this script I get this message
*./build
Compiling the overlay from .dts to .dtbo

Input formats are:
dts - device tree source text
dtb - device tree blob
fs - /proc/device-tree style directory
-o, --out <arg>
Output file
-O, --out-format <arg>
Output formats are:
dts - device tree source text
dtb - device tree blob
asm - assembler source

Blob version to produce, defaults to %d (for dtb and asm output)
-d, --out-dependency <arg>
Output dependency file
-R, --reserve <arg>

-S, --space <arg>
Make the blob at least <bytes> long (extra space)
-p, --pad <arg>

I did install device-tree-compiler before issuing this command.

What is wrong here?
