Debug and Trace Services Layer (DTSL)

Describes the Arm Debugger Debug and Trace Services Layer (DTSL).

DTSL is a software layer that sits between the debugger and the RDDI target access API. Arm Debugger uses DTSL to:

  • Create target connections.
  • Configure the target platform to be ready for debug operations.
  • Communicate with the debug components on the target.

As a power user of Arm Debugger, you might need to use DTSL:

  • As part of new platform support.
  • To extend the capabilities of Arm Debugger.
  • To add support for custom debug components.
  • To create your own Java or Jython programs which interact with your target.
