@80802680
我们这边用你的字体测试，没有发现卡死现象，请问你如果直接用base_demo的原始字体，是否会出现这种情况。

make freetype-distclean 一下，然后再重新编译一下，试试这个是否可以解决


哦，刚用更新了SDK包，用最新的SDK包，编译后运行正常了，

以前没有更新，用的是1月左右的SDK包有这个BUG。

@80802680

LPKG_LVGL_THREAD_STACK_SIZE 这里的stack加大一点试试。
我测试的时候也出现卡死问题，修改了stack

LPKG_LVGL_THREAD_STACK_SIZE？

找遍了都没找到这个名称

请发一下你的字库，还有代码的改动点，我们这边测试一下。


1. make menuconfig，进入 menuconfig

	ArtInChip Luban SDK Configuration  --->
    Third-party packages  --->
    freetype  --->选择但取消二进制预编译

2.在lv_conf.h头文件中打开宏定义

	#define   LV_USE_FREETYPE 1
	#define   LV_BUILD_EXAMPLES 1

3.修改main.c中的入口函数：

   /*Create a Demo*/
    void base_ui_init();
    base_ui_init();

4.复制TTF字体到lvgl-ui/base_ui/asserts/font目录下

5. 修改lvgl-ui\base_ui\base_ui.c

void base_ui_init()
{
    FAKE_IMAGE_INIT(bg_dark, 1024, 600, 0, 0x00000000);

    img_bg = lv_img_create(lv_scr_act());
    lv_img_set_src(img_bg, LVGL_PATH(global_bg.png));
    lv_obj_set_pos(img_bg, 0, 0);


    /*Create a font*/
    static lv_ft_info_t info;
    /*FreeType uses C standard file system, so no driver letter is required.*/
    info.name = "/usr/local/share/lvgl_data/font/GenJyuuGothic-Light-2.ttf";
    info.weight = 48;
    info.style = FT_FONT_STYLE_NORMAL;
    info.mem = NULL;
    if(!lv_ft_font_init(&info)) {
        LV_LOG_ERROR("create failed.");
    }


    /*Create style*/
    static lv_style_t font_style;
    lv_style_init(&font_style);
    lv_style_set_text_font(&font_style, info.font);


    main_title = lv_label_create(img_bg);
    lv_obj_set_width(main_title, LV_SIZE_CONTENT);
    lv_obj_set_height(main_title, LV_SIZE_CONTENT);
    lv_obj_align(main_title, LV_ALIGN_TOP_MID, 0, 0);
    lv_obj_set_pos(main_title, 0, 10);
    lv_obj_add_style( main_title, &font_style, 0 );
    lv_label_set_text(main_title, "Meter");
    lv_obj_set_style_text_color(main_title, lv_color_hex(0xFFFFFF), LV_PART_MAIN | LV_STATE_DEFAULT);
    lv_obj_set_style_text_opa(main_title, 255, LV_PART_MAIN | LV_STATE_DEFAULT);
	
	

    bg_fps = lv_label_create(img_bg);
    lv_obj_set_width(bg_fps, LV_SIZE_CONTENT);
    lv_obj_set_height(bg_fps, LV_SIZE_CONTENT);
    lv_obj_align(bg_fps, LV_ALIGN_TOP_RIGHT, 0, 0);
    lv_obj_set_pos(bg_fps, -130, 50);
    lv_label_set_text(bg_fps, "");
    lv_obj_set_style_text_color(bg_fps, lv_color_hex(0xFFFFFF), LV_PART_MAIN | LV_STATE_DEFAULT);
    lv_obj_set_style_text_opa(bg_fps, 255, LV_PART_MAIN | LV_STATE_DEFAULT);
    lv_obj_set_style_text_font(bg_fps, &ui_font_Title, LV_PART_MAIN | LV_STATE_DEFAULT);


    bg_logo = lv_label_create(img_bg);
    lv_obj_set_width(bg_logo, LV_SIZE_CONTENT);
    lv_obj_set_height(bg_logo, LV_SIZE_CONTENT);
    lv_obj_align(bg_logo, LV_ALIGN_BOTTOM_RIGHT, 0, 0);
    lv_obj_set_pos(bg_logo, -30, -30);
    lv_obj_add_style( bg_logo, &font_style, 0 );
    lv_label_set_text(bg_logo, "矢量字");
    lv_obj_set_style_text_color(bg_logo, lv_color_hex(0x00FFFF), LV_PART_MAIN | LV_STATE_DEFAULT);
    lv_obj_set_style_text_opa(bg_logo, 255, LV_PART_MAIN | LV_STATE_DEFAULT);

其它的都不变
