[求助] 调试stm32时运行一条语句后进入硬中断HardFault_Handler

typedef struct _PARA_SET
{
#if STRING_STORE_USE_ARRAY
char             name[NAME_STRING_MAX];
char             alias[ALIAS_STRING_MAX];
char             unit[UNIT_STRING_MAX];
char             strValue[LINE_STRING_MAX];
#else
char             *name;
char             *alias;
char             *unit;
char             *strValue;

#endif

tParaType          type;
FLOAT32          value;
FLOAT32          MaxValue;
FLOAT32          MinValue;
FLOAT32          DefValue;
}tParaSet;

tParaSet DevCommSets[3];

static void DEV_ReadCommSets(void)
{
  UINT32 i, value;

tParaSet *pSets = DevCommSets;

DF_ReadMainMemoryPage(SAVE_DEV_COMM_SETS_PAGE,
                        DEV_ReadData, COMM_MAX_SETS * 4 + 4);

for (i = 0; i < COMM_MAX_SETS; i++)
{
      value = BytesToDword(&DEV_ReadData[i * 4]);

      pSets->value = value;
      if ((pSets->value > pSets->MaxValue) || (pSets->value < pSets->MinValue))
      {
         pSets->value = pSets->DefValue;
      }
      pSets++;
}

DEV_CommSetsCrc = BytesToDword(&DEV_ReadData[i * 4]);
}
调试过程如下：

(gdb) n
Reset_Handler () at startup_stm32f10x_hd.c:262
262       SystemInit();
(gdb) n
268          __Init_Data();
(gdb) n
271       main();
(gdb) n

Breakpoint 1, DEV_ReadCommSets () at device.c:980
980          for (i = 0; i < COMM_MAX_SETS; i++)
(gdb) n
982             value = BytesToDword(&DEV_ReadData[i * 4]);
(gdb) n
984                pSets->value = value;                //运行这条语句后进入硬中断void HardFault_Handler(void){ while(1){} }中，不知道为什么？
(gdb) n
HardFault_Handler () at stm32f10x_it.c:61
61       {
(gdb) n
64          {}
