Customize adrv9364-z7020


I am new to all this and there are basic things that I do not understand in the guides provided by analog device.

I want to customize my adrv9364-z7020 board. For this I saw that I must modify the device-tree 
that comes in the linux image that is loaded in the micro SD card. It could guide me and tell me where to start. Or what tests should I do before modifying the device-tree? Thank you, Nicole.
