Move console, bt-mon, etc to RTT

Question

I need to move everything off of UART0 so I can use it for my touchscreen 
 On a previous post I was told I could move everything to RTT in the overlay, but when I try to do that with the snippet below: 
 zephyr,console = &rtt; zephyr,uart-mcumgr = &rtt; zephyr,bt-mon-uart = &rtt; 
 I get the following error: 
 Unknown reference to &rtt for all three lines. 
 In the DTS I have this: 
 zephyr,console = &uart0; zephyr,shell-uart = &uart0; zephyr,uart-mcumgr = &uart0; zephyr,bt-mon-uart = &uart0; 
 How do I change those to RTT? What am I missing?

Hi, 
 
 You will need to define this as a root node (that is a node that starts with "/ { some_definitions = some_state; };") : 
 / {
	chosen {
 zephyr,console = &rtt0;
	};

rtt0: rtt_chan0 {
 compatible = "segger,rtt-uart";
 status = "okay";
	};
}; 
 
 Remember to delete the build folder and regenerate the project. 
 
 Kind regards, 
 Håkon
