100ask-t113-pro lvds调试问题

[zzz555]

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
echo 8 > /sys/class/disp/disp/attr/colorbar
