Debug and Trace Services Layer (DTSL) is a software layer within the DS-5 Debugger stack. It sits between the debugger and the RDDI target access API.
DTSL takes responsibility for:
DTSL is implemented as a set of Java classes which are typically implemented (and possibly extended) by Jython scripts. A typical DTSL instance is a combination of Java and Jython.
A simple example of this is when DTSL connects to a simple platform
Cortex®-A8, ETM, and ETB. When the DTSL connection is activated it runs a Jython script to
create the DTSL configuration. This configuration is populated with a Java
Device object called
TraceSource object called
ETM, and a
TraceCaptureDevice object called
The Debugger, or another program using DTSL, can then access the DTSL configuration to
retrieve these objects and perform debug and trace operations.
ARM has made DTSL available for your own use so that you can create Java or Jython programs to access and control the target platform.
