RTT Client application
Included in the Segger download is an application titled “J-LINK RTT Viewer”. This
application allows information sent from the MCU to be either displayed on a terminal or
logged into a file. Alternatively, data from the keypad of the PC can be sent to the MCU.
When the application is first opened, a dialog box is shown that allows the user to configure
the connection. Please set the below options and control block address. The control block
is a designated piece of memory for buffering information to and from the MCU. It is
configured in software as shown in the next section.
Note: An error message may be displayed stating the J-Link does not recognize the MCU. If
that occurs, hit “ok” and select the generic Cortex-M4 in the subsequent dialogue box. This
error message should only occur on the first attachment to the board with the MDK.
The ‘splash’ screen should appear in the terminal window, as shown here.
