    使用FR8008GP-U LVGLDemo创建控件反复重启
    工程：fr8000u_sdk\examples\evm\gui_demo_8_1_BLE
    修改部分：将蓝牙，PSRAM部分和触摸都去掉了，初始化LVGL和LCD7789驱动都没问题，只要我创建LVGL控件，芯片就会复位

    屏蔽掉创建按键就不会复位了，是不是栈和堆溢出，如果是在哪设置呢

    static void my_disp_flush(lv_disp_drv_t * disp, const lv_area_t * area, lv_color_t * color_p)
    {
    st7789v_disp_flush(area->x1,area->x2,area->y1,area->y2,color_p->full);
    lv_disp_flush_ready(disp);
    }

    {
    //touchpad_init(NULL);
    display_init();

    lv_disp_draw_buf_init(&draw_buf_dsc_1,buf_1,NULL,LV_BUFFER_SIZE);
