System Workbench
System Workbench is an Eclipse-based IDE developed by the AC6 in partnership with ST.
Setup for J-Link Debug
The setup for debugging your target with J-Link probes is exactly the same as for an Eclipse IDE project. For further information on how to setup your debugging environment please see WikiSegger Eclipse Setup or Workbench STM32 j-Link Setup.
Thread-Aware Example
In the below link you may find a Thread-aware example using SEGGER J-Link freeRTOS plugin under Eclipse. This example was generated with ST CubeMX and works out-of-the-box and you may use it as a starting point for your project.

If you already have a running project with freeRTOS or embOS and you wish to add Thread-Aware support you can simply add -rtos GDBServer/RTOSPlugin_FreeRTOS under "other options"(see below). These Plugins can be found under J-Link installation folder: GDBServer\RTOSPlugin_embOS.dll and GDBServer\RTOSPlugin_FreeRTOS.dll
