Hey Dakefeng,

There is a way that this can be done in Linux. There is a utility called 'device tree compiler' that can compile .dts files into .dtb and vice versa. Xilinx has a wiki page that talks about this and its usage a little bit. I'm sure a quick search could also find you some more detailed information about it, but it is possible to do!

Thanks, I found the script under kernel tools dtc, it works like magic

 

~/gits/linux-xlnx/scripts/dtc/dtc -I dtb -O dts -o devicetree.dts devicetree.dtb
