Connection Settings

RTT Viewer can be used in two modes:
Stand-alone, opening an own connection to J-Link and target.
In attach mode, connecting to an existing J-Link connection of a debugger.
Stand-alone connection settings
In stand-alone mode RTT Viewer needs to know some settings of J-Link and target
device.
Select USB or TCP/IP as the connection to J-Link. For USB a specific J-Link serial
number can optionally be entered, for TCP/IP the IP or hostname of the J-Link has to
be entered.
Select the target device to connect to. This allows J-Link to search in the known RAM
of the target.
Select the target interface and its speed.
The RTT Control Block can be searched for fully automatically, it can be set to a fixed
address or it can be searched for in one or more specific memory ranges.
Attaching to a connection
In attach mode RTT Viewer does not need any settings. Select Existing Session.
For attach mode a connection to J-Link has to be opened and configured by another
application like a debugger or simply J-Link Commander. If the RTT Control Block
cannot be found automatically, configuration of its location has to be done by the
debugger / application.
