     81== Compiling the Device Tree
     82If you need to change the device-tree you can easily compile it on a Linux system using the dtc app from the device-tree-compiler package:
     83{{{#!bash
     84apt-get install device-tree-compiler
     85dtc -O dtb -o imx6dl-gw51xx.dtb imqx6dl-gw51xx.dts
     86}}}
     87You can also de-compile a dtb back to a dts:
     88{{{#!bash
     89$ dtc -I dtb -O dts imx6dl-gw51xx.dtb 
     90}}}
