请问是哪里配置出错了

lvds屏幕不显示，用示波器测量两个时钟引脚都是高电平，这是什么原因

@y97788 在 ubifs卷挂载问题 中说：

ubiupdatevol /dev/ubi0_1 boot-resource.fex
这样可以修改整个卷的数据，但是如何修改boot-resource.fex里bootlogo.bmp，或者如何将新的bootlogo.bmp打包生成boot-resource.fex文件，然后再用上面命令来更新卷数据

你好，我也碰到了这个问题，请问你解决了吗

Error: mkfs.ubifs was built without crypto support.
请问大佬怎么解决呀

@jr_online 老哥，我目前也遇到这个问题，但是补丁没法下载，能私信发我一份吗，非常感谢

有偿请教，驱动ic是ili9881c，800x1280的屏，加q1142003732

用的是800x1280的mipi屏，驱动用的是tft08006，用示波器测信号，发现数据线都有正常信号，时钟线却没有正常信号，用打印信息看初始化代码，也有正常使能时钟，请问这到底是哪里的问题？

RGB屏是可以正常显示的，但是配置lvds设备树时，却显示异常，用fbshow写图片也无法显示
设备树lvds配置如下：
&lcd0 {
lcd_used = <1>;

    lcd_driver_name     = "default_lcd";
    lcd_backlight       = <50>;
    lcd_if              = <3>;

    lcd_x               = <800>;
    lcd_y               = <600>;
    lcd_width           = <108>;
    lcd_height          = <94>;
    lcd_dclk_freq       = <39>;

    lcd_pwm_used        = <1>;
    lcd_pwm_ch          = <7>;
    lcd_pwm_freq        = <50000>;
    lcd_pwm_pol         = <0>;
	
lcd_hbp             = <88>;
    lcd_ht              = <1024>;
    lcd_hspw            = <64>;
    lcd_vbp             = <15>;
    lcd_vt              = <625>;
    lcd_vspw            = <6>;

    lcd_lvds_if         = <0>;
    lcd_lvds_colordepth = <0>;
    lcd_lvds_mode       = <1>;

    lcd_frm = <0>;
    lcd_io_phase = <0x0000>;
    lcd_gamma_en        = <0>;
    lcd_bright_curve_en = <0>;
    lcd_cmap_en         = <0>;
	
deu_mode            = <0>;
    lcdgamma4iep        = <22>;
    smart_color         = <90>;

    pinctrl-0 = <&lvds0_pins_a>;
    pinctrl-1 = <&lvds0_pins_b>;

};
请问是设备树配置出错了吗？
显示异常的现象：
用fbshow显示显示png图片不能显示，但过会儿屏幕有蓝色
使用接口自带 colorbar
