RealView
DebuggerYou can use the Step buttons, or the Step commands in the Debug menu to step through threads in a multi-threaded image.
In HSD mode
You must set a breakpoint to stop the image so that you can step through the code. A step instruction from any Code window, regardless of its attachment, steps the thread that is current when the processor stops.
You can change current thread manually
to see the registers and variables for a different thread, but if you
begin to step again, RealView Debugger automatically sets current thread
to be the thread that was running when the processor stopped.
In RSD mode
In RSD mode, you can step any captive thread without having to stop the target.
