How to setup watchpoints to break when access data for target debug

isaotakashima — Sun, 28 May 2017 14:10:42 GMT

I want to use watchpoints to break when access (read and/or write) data for target board debug.

IAR Systems EWARM supported this feature that "Set Data Breakpoint", KEIL MDK-ARM also supported that "Set access breakpoint".

I found the following description in 4 Known Issues and Workarounds of Kinetis Design Studio 3.2.0 Release Notes.

Conditional watchpoints and breakpoints: Conditional breakpoints and watchpoints, including those using ignore counts, do not work always.
Workaround: do not use conditions for breakpoints and watchpoints, instead check for condition in the code and set a normal breakpoint.

Therefore I believe that KDS does not support watchpoints debugging to break when access (read and/or write) data.

Am I correct?

How about MCUxpresso? Is it support watchpoints debugging?

Please reply as soon as possible.

Best regards,

Takashima

Hi Isao,

You are correct, this is a known issue in KDS, it is recommended to use normal breakpoints instead of conditional breakpoints or watchpoints. Regarding MCUXpresso, those limitations are not present on this IDE.

Hope it helps!
