H7-TOOL高速DAPLINK调试带看门狗的程序会出现打断点后，无法正常暂停，解决办法比较简单，在Option选项冻结看门狗即可

eric2013

程序使用了看门狗不像低功耗，低功耗会直接调试不正常，而看门狗的话，如果在程序里面打了断点，会出现程序还在正常运行的假象。

现象就是打断点的地方会一闪而过，闪烁过的时间由喂狗溢出时间决定。

解决办法比较简单：
芯片专门设计的功能，就是为了方便用户在低功耗和看门狗模式下载可以继续使用调试。以STM32H7为了，可以在MDK option选项的此处进行设置：



也可以直接调用API设置：

硬汉哥，JLINK或者ST-LINK有类似功能吗？

点开后，有这个配置项就可以的。
