# Both of above commands are using dtc built with linux kernel source. 
# However you can also use dtc binary comes with ubuntu packages. For this you
# need to install following package:

sudo apt-get install -y device-tree-compiler

# Ubuntu device-tree-compiler package comes with another utility known as fdtdump. 
# fdtdump can also be used to convert dtb file into dts.

fdtdump <dtb_file> > <dts_dump>
