I'm not sure what you mean by debug procedure, but theexamples should give log messages that you can view with the RTT Viewer. With RTT the SWD debug interface is used to send information to the J-Link which forwards the information to a PC++, see this for more information.

Also, there is a tutorial here, it is not for the Thread SDK though.

For example when I run the Thread CLI example I get:

:INFO:Thread version: OPENTHREAD/g7c777392-dirty; NRF52840; Mar  3 2017 12:38:57
:INFO:Network name:   OpenThread
:INFO:State changed! Flags: 0x00000521 Current role: 1
