10 STM32F4 STemWin移植 LCD_X_DisplayDriver卡死

在使用STM32F429IGT6移植完STemWin后，初始化时卡死在GUI_Init函数中，加了打印后发现执行顺序：GUI_X_Config执行成功-->LCD_X_Config执行成功，LCD_X_Config函数第一次进入后正常，第二次进入后卡死在里面。这该怎么办？

```c
int LCD_X_DisplayDriver(unsigned LayerIndex, unsigned Cmd, void *pData)
{
    rt_kprintf("enter LCD_X_DisplayDriver Cmd : %d\n",Cmd);
    int r;
    (void)LayerIndex;
    (void)pData;

switch (Cmd)
    {
    case LCD_X_INITCONTROLLER:
    {
        //
        // Called during the initialization process in order to set up the
        // display controller and put it into operation. If the display
        // controller is not initialized by any external routine this needs
        // to be adapted by the customer...
        //
        // ...
        return 0;
    }
    case LCD_X_SETSIZE:
        {
            //
            // Called during the initialization process in order to set up the
            // display controller and put it into operation. If the display
            // controller is not initialized by any external routine this needs
            // to be adapted by the customer...
            //
            // ...
            return 0;
        }
    default:
        r = -1;
    }
    rt_kprintf("exit LCD_X_DisplayDriver r : %d\n",r);
    return r;
}
```
