Many developers who start work with a Cortex-M microcontroller assume that its debug system is a form of “JTAG (Joint Test Action Group)” interface. In fact a Cortex-M processor has a debug architecture called “CoreSight” which is considerably more powerful. In addition to the run control and memory access ...
