Using the J-Link Adapter

The J-Link Adapter fetches RTT and SWO data from a J-Link debug probe.  The raw input data will be processed by a configurable reader. 

Screen Cast: Using the J-Link Adapter

Modes

  • In "RTT via J-Link RTT tools" mode, the adapter starts RTT Logger tool in background and reads its output.  
  • If "RTT via GDB server" mode is chosen, the adapter opens and reads a configurable tcp port provided by the GDB server.
  • With "SWO via GDB server" mode is chosen, the adapter opens and reads a another tcp port provided by the GDB server.

Configuration

RTT via J-Link RTT tools

For the fields "Device name" ,"RTT channel", "Interface" ,"Speed" and "Rtt address" please refere to the J-Link documentation.
If the RTT tools are not accessible via the system path variable, please enter the installation path.

RTT via GDB server

  • Server: Server address or "localhost".  
  • Socket: Socket number of the RTT output

SWO via GDB server

  • Server: Server address or "localhost".  
  • Socket: Socket number of the SWO output

Serializer

Configure the serializer by selecting a reader and optionally a reader configuration (some reader require a configuration, e.g. the CSV reader).
You may use the buttons '+' and '...' to add and manage existing reader configurations (Preferences).
You may use the "Test Line Reader" (extracts lines from the raw input) and "Test Block Reader" (extract fixed size byte blocks) for debugging purpose.

Synchronization

Using a multi port adapter, you can combine an unlimited number of different input ports. The synchronization section of the adapters allows you to synchronize inputs with different domain bases (e.g. each input has its own time base). See 11 Synchronisation.
