28388的M4核：Break at address "0x41c4" with no debug information available, or outside of program code.

user6225110

你好，我最近在调试28388的M4核，程序从flash启动，目前CpuTimer，UART及其中断都已经调试完成了，都没有问题。现在在调MCAN模块，在调试好的程序基础上添加了C2000提供的MCAN模块例程，单步执行，运行到函数CM_init();// Initialize device clock and peripherals时，进入函数就会报Break at address "0x41c4" with no debug information available, or outside of program code.1，程序一直停留在CM_init()函数的“{”处，请问是什么导致的，谢谢。

一下是我的cmd文件

Break at address "0x41c4" with no debug information available, or outside of program code

这个信息的话，是表明在该地址处没有源码，所以编译器找不到源码，严格来说不能算是错误。

若是可以的话，请私信一下您的工程，我们具体看一下，谢谢
