错误定位问题

发布于 2019-09-05 16:47:46 浏览：2253 订阅该版

1、这个帖子[https://www.rt-thread.org/qa/for ... ypeid%26typeid%3D67](https://www.rt-thread.org/qa/forum.php?mod=viewthread&tid=2300&extra=page%3D1%26filter%3Dtypeid%26typeid%3D67)是不是已经集成在cm_backtrace里面了？感觉看的不是很懂。
2、另外跟着RT-Thread温控系统DIY做的练习，不定期会进入如下的Hardfault，不知道该怎么定位，看信息好像和论坛13年的帖子不太一样。
