Runtime Object Viewer

Debuggers may include the Runtime Object Viewer (ROV) plug-in that provides insight into the current state of FreeRTOS, including task states, stacks, and so forth.

This section discusses some ROV views useful for debugging and profiling.

Viewing the State of Each Task

The Task Detailed view is useful for seeing the state of each task and its related runtime stack usage. This picture below shows the state the first time the user-thread is called.

ROV Task Detail View

The following table explains the column in ROV Task Detail View

Task Detail View Item Explanation

Address

The memory location of the Task_Struct instance for each task.

TaskName

The name of the entry function of the task.

Priority

The RTOS priority for the task.

State

Current state of the task.

StackSize

The size of the runtime stack, configured when instantiating a task.

StackPeak

The maximum run-time stack memory used based on watermark in RAM, where the stacks are prefilled with 0xBE and there is a sentinel word at the end of the run-time stack.

StackLimit

The logical top of the runtime stack of the task.

Note

Function calls may push the stack pointer out of the run-time stack, but not actually write to the entire area. A stack peak near stackSize but not exceeding it may indicate stack overflow.
