基于gcc+stm32F103+makefile移植cmbacktrace
一、环境配置
1、编译环境使用gcc+makefile
2、我的开发板使用的是stm32F103,
二、下载cmbacktrace
1、下载地址：https://github.com/armink/CmBacktrace，在github上下载源代码，可以直接下载zip或者用git clone下来
2、下载后我们只需要将CmBacktrace目录下的cm_backtrace添加到我们的项目工程下
三、修改相关文件，mb_cfg.h，cm_backtrace.c，cmb_def.h，链接文件，
mb_cfg.h文件
cmb_def.h文件
这里_sstack,_estack,_stext,_etext就是用来做栈回溯的时候使用，这里根据自己的编译器看对应的信息，
_sstack:是栈的开始
_estack:栈底
_stext:段开始的地方
_etext:段结束的地方
下面是我ld文件的配置，可以作为参考

将fault_handler/gcc目录下的cmb_fault.s添加到项目编译中，源码中是.S，我这里修改成了.s为了方便编译
然后将stm32f10x_it.c中的HardFault_Handler函数注释掉，因为该函数我们会通过cmb_fault.s文件中调用
在main函数中添加初始化函数，以及一个可以产生总线错误的函数
系统控制寄存器配置可以参考下面文章：https://blog.csdn.net/zoomdy/article/details/79303426
最后我们在makefile中配置编译导入头文件，以及.c文件
在makefile目录下运行make -j4编译生成bin文件和hex文件后下载到开发板
效果如下：
在addr2line中放入编译出来的elf文件，运行addr2line命令
对应的函数以及行号都使正确的，这里是空指针
