WebOct 18, 2011 · Using the MMU or an MPU (on other processors such as embedded), can be used to implement "hardware watchpoints"; however, some processors (e.g., many Arm implementations) have dedicated watchpoint hardware accessed via a debug port. This has some advantages over using an MMU or MPU. If you use the MMU or MPU approach: WebAug 11, 2024 · The easiest way to set a watchpoint is to use the Eclipse Outline view (see “ Watchpoints: Data Breakpoints “): Toggle Watchpoint I configure it as a write watchpoint, so it stops the debugger when a write to that variable or memory address happens: Write Watchpoint If I run that application out of reset, it will stop the debugger in three places:
