STM32F405RGT6 在IAR 下点亮LED灯，移植rt-thread-nano 进入这个循环里面while(1)停在这个位置
```void rt_hw_hard_fault_exception(struct exception_info * exception_info)
{
    extern long list_thread(void);
    struct stack_frame* context = &exception_info->stack_frame;

if (rt_exception_hook != RT_NULL)
    {
        rt_err_t result;

result = rt_exception_hook(exception_info);
        if (result == RT_EOK)
            return;
    }

rt_kprintf("psr: 0x%08x ", context->exception_stack_frame.psr);

rt_kprintf("r00: 0x%08x ", context->exception_stack_frame.r0);
 rt_kprintf("r01: 0x%08x ", context->exception_stack_frame.r1);
 rt_kprintf("r02: 0x%08x ", context->exception_stack_frame.r2);
 rt_kprintf("r03: 0x%08x ", context->exception_stack_frame.r3);
 rt_kprintf("r04: 0x%08x ", context->r4);
 rt_kprintf("r05: 0x%08x ", context->r5);
 rt_kprintf("r06: 0x%08x ", context->r6);
 rt_kprintf("r07: 0x%08x ", context->r7);
 rt_kprintf("r08: 0x%08x ", context->r8);
 rt_kprintf("r09: 0x%08x ", context->r9);
 rt_kprintf("r10: 0x%08x ", context->r10);
 rt_kprintf("r11: 0x%08x ", context->r11);
 rt_kprintf("r12: 0x%08x ", context->exception_stack_frame.r12);
 rt_kprintf(" lr: 0x%08x ", context->exception_stack_frame.lr);
 rt_kprintf(" pc: 0x%08x ", context->exception_stack_frame.pc);

if(exception_info->exc_return & (1 << 2) )
 {
 rt_kprintf("hard fault on thread: %s ", rt_thread_self()->name);

#ifdef RT_USING_FINSH
 list_thread();
#endif /* RT_USING_FINSH */
 }
 else
 {
 rt_kprintf("hard fault on handler ");
 }

#ifdef RT_USING_FINSH
    hard_fault_track();
#endif /* RT_USING_FINSH */

while (1);
}
```
