+OpenOCD includes RTOS support, this will however need enabling as it defaults to disabled.
+It can be enabled by passing @option{-rtos} arg to the target @xref{rtostype,,RTOS Type}.
+
+@* An example setup is below:
+
+@example
+$_TARGETNAME configure -rtos auto
+@end example
+
+This will attempt to auto detect the RTOS within your application.
+
+Currently supported rtos's include:
+@itemize @bullet
+@item @option{eCos}
+@item @option{ThreadX}
+@item @option{FreeRTOS}
+@item @option{linux}
+@item @option{ChibiOS}
+@item @option{embKernel}
+@end itemize
+
+@quotation Note
+Before an RTOS can be detected it must export certain symbols otherwise it cannot be used by
+OpenOCD. Below is a list of the required symbols for each supported RTOS.
+@end quotation
+
+@table @code
+@item eCos symbols
+Cyg_Thread::thread_list, Cyg_Scheduler_Base::current_thread.
+@item ThreadX symbols
+_tx_thread_current_ptr, _tx_thread_created_ptr, _tx_thread_created_count.
+@item FreeRTOS symbols
+pxCurrentTCB, pxReadyTasksLists, xDelayedTaskList1, xDelayedTaskList2,
+pxDelayedTaskList, pxOverflowDelayedTaskList, xPendingReadyList,
+xTasksWaitingTermination, xSuspendedTaskList, uxCurrentNumberOfTasks, uxTopUsedPriority.
+@item linux symbols
+init_task.
+@item ChibiOS symbols
+rlist, ch_debug, chSysInit.
+@item embKernel symbols
+Rtos::sCurrentTask, Rtos::sListReady, Rtos::sListSleep,
+Rtos::sListSuspended, Rtos::sMaxPriorities, Rtos::sCurrentTaskCount.
+@end table
+
+For most RTOS supported the above symbols will be exported by default. However for
+some, eg. FreeRTOS @option{xTasksWaitingTermination} is only exported
+if @option{INCLUDE_vTaskDelete} is defined during the build.
