HardFault_Handler - 输出PC值

一、首先需要找到出现故障的地方

1.在.c文件下自定义hard_fault_handler_c函数

void hard_fault_handler_c(uint32_t* hardfault_args)

{

    static unsigned int stacked_lr;

    static unsigned int stacked_pc;

    stacked_lr = ((unsigned long) hardfault_args[5]);

    stacked_pc = ((unsigned long) hardfault_args[6]);

    __breakpoint(0);

    while(1);

}
