异常HardFault_HandlerC的跟踪思路

你好，
系统老是挂死在hardFault_handler.c中空白HardFault_HandlerC(无符号长* hardfault_args)的如下地方:
void HardFault_HandlerC(unsigned long *hardfault_args)
｛

如果(DEVELOPMENT_DEBUG)
｛
SetBits16 (SYS_CTRL_REG DEBUGGER_ENABLE 1);//启用调试器能够重新连接
*(volatile unsigned long *)(STATUS_BASE) = hardfault_args[0];/ / R0
*(volatile unsigned long *)(STATUS_BASE + 0x04) = hardfault_args[1];/ / R1
*(volatile unsigned long *)(STATUS_BASE + 0x08) = hardfault_args[2];/ / R2
*(volatile unsigned long *)(STATUS_BASE + 0x0C) = hardfault_args[3];/ / R3
*(volatile unsigned long *)(STATUS_BASE + 0x10) = hardfault_args[4];/ / R12
*(volatile unsigned long *)(STATUS_BASE + 0x14) = hardfault_args[5];/ / LR
*(volatile unsigned long *)(STATUS_BASE + 0x18) = hardfault_args[6];/ /电脑
*(volatile unsigned long *)(STATUS_BASE + 0x1C) = hardfault_args[7];/ / PSR
*(volatile unsigned long *)(STATUS_BASE + 0x20) = (unsigned long)hardfault_args;/ /堆栈指针

*(volatile unsigned long *)(STATUS_BASE + 0x24) = (*((volatile unsigned long *)(0xE000ED28));/ / CFSR
*(volatile unsigned long *)(STATUS_BASE + 0x28) = (*((volatile unsigned long *)(0xE000ED2C));/ / HFSR
*(volatile unsigned long *)(STATUS_BASE + 0x2C) = (*((volatile unsigned long *)(0xE000ED30));/ / DFSR
*(volatile unsigned long *)(STATUS_BASE + 0x30) = (*((volatile unsigned long *)(0xE000ED3C));/ / AFSR
*(volatile unsigned long *)(STATUS_BASE + 0x34) = (*((volatile unsigned long *)(0xE000ED34));/ / MMAR
*(volatile unsigned long *)(STATUS_BASE + 0x38) = (*((volatile unsigned long *)(0xE000ED38));/ / BFAR
如果(USE_WDOG)
wdg_freeze ();/ /停止WDOG

if (GetWord16(SYS_STAT_REG) & DBG_IS_UP) == DBG_IS_UP)
__asm(“BKPT # 0 \ n”);//挂死在此处
其他的
(1);
｝

｝

这个一般是什么原因啊？硬件的有虚焊还是？软件上能定位这个问题吗，前面的那些寄存器有助于定位问题吗？
谢谢！
