总线错误地址52370036

发布于 2019-09-11 10:03:16 浏览：2762 订阅该版

cm_backtrace里面出现
```[40140112] E/cmb mqtt0: The bus fault occurred address is 52370036```这里的“52370036”是十六进制地址吗，如果是的话，根据stm32f103ze的芯片手册，0x40024400-0x5FFFFFFF是Reserved，错误信息为什么会定位到这里呢？

感觉cm_backtrace玩不转，想问下还有别的办法定位错误信息吗，调试经验少，请高手指教下。

下面附一下cm_backtrace的log

??:0```还有我的输出文件是rt-thread.axf，但给的信息总是addr2line -e rtthread.axf这样的，我在keil中把输出文件改为rtthread.axf，然后信息就会变成addr2line -e rt-thread.axf这样的，不知道我是哪里做错了？:'(
