软件包用的这个：[STemWin](https://packages.rt-thread.org/itemDetail.html?package=STemWin)

运行到`GUI_Init（）`就执行不下去了

不知道怎么放源码
一下 GUI_TEST.C
```c
#include "GUI_Test.h"
#include "GUI.h"
#include "GUIDemo.h"

static void test_thread(void *param)
{
  unsigned int rt_err;  
	CRC_HandleTypeDef   CrcHandle;
    CrcHandle.Instance = CRC; 
    HAL_CRC_Init(&CrcHandle);
	
   rt_err=GUI_Init();
	
	rt_kprintf("ST EMWIM INIT FAEILED ");

GUIDEMO_Main();
}

static int gui_test_init(void)
{
    rt_thread_t tid;
    tid = rt_thread_create("gui_test",
                           test_thread, RT_NULL,
                           2048,
                          21, 10);
    if (tid != RT_NULL)
        rt_thread_startup(tid);
    return RT_EOK;
}
INIT_APP_EXPORT(gui_test_init);
```

以下`GUIconf.c`,可能和ram分配有关
