已经使用代码
```SRAM_Init();
	{
        unsigned char * p_extram = (unsigned char *)STM32_EXT_SRAM_BEGIN;
        unsigned int temp;

rt_kprintf("
mem testing....");
        for(temp=0; temp<(STM32_EXT_SRAM_END-STM32_EXT_SRAM_BEGIN); temp++)
        {
            *p_extram++ = (unsigned char)temp;
        }

p_extram = (unsigned char *)STM32_EXT_SRAM_BEGIN;
        for(temp=0; temp<(STM32_EXT_SRAM_END-STM32_EXT_SRAM_BEGIN); temp++)
        {
            if( *p_extram++ != (unsigned char)temp )
            {
                rt_kprintf("
memtest fail @ %08X
system halt!!!!!",(unsigned int)p_extram);
                while(1);
            }
        }
        rt_kprintf("
mem test pass!!
");
    }/* memtest */```
测试通过，然后就提示hard fault on thread 然后狂提示初始化，请问是什么问题
