R528LVDS接口输出怎么配置，在设备树里面配置了，感觉没有效果呀？

@wyljkl 解决了老哥？当时点亮了不？我也在搞R528
-
@goodwill1945 当时整亮了，硬件问题，但是现在好久了，也没在之前的公司了。
这是当时的lcd配置，你可以参考一下，：
&lcd0 {
lcd_used = <1>;lcd_driver_name = "default_lcd"; lcd_backlight = <50>; lcd_if = <3>; lcd_x = <800>; lcd_y = <600>; lcd_width = <150>; lcd_height = <94>; lcd_dclk_freq = <40>; lcd_pwm_used = <1>; lcd_pwm_ch = <7>; lcd_pwm_freq = <50000>; lcd_pwm_pol = <1>; lcd_pwm_max_limit = <255>; /*lcd_bl_en = <&pio PD 20 GPIO_ACTIVE_HIGH>;*/ lcd_hbp = <46>; lcd_ht = <1501>; lcd_hspw = <10>; lcd_vbp = <23>; lcd_vt = <1270>; lcd_vspw = <5>; lcd_lvds_if = <0>; lcd_lvds_colordepth = <1>; lcd_lvds_mode = <0>; lcd_frm = <1>; lcd_hv_clk_phase = <0>; lcd_hv_sync_polarity= <0>; 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>; }; -
@wyljkl 感谢回复，除了设备树还要改别的不？
-
@wyljkl 公司名字我肯定能猜对，有兴趣私聊下不？
-
@wyljkl 看你交接文档受益良多，祝前程似锦。我只改设备树是点不亮的。不过现在也不做这个了无所谓了
-
@goodwill1945 在 R528LVDS接口输出怎么配置，在设备树里面配置了，感觉没有效果呀？ 中说：

哈哈哈，这居然都遇到了，圈子好小
-
@xiaowenge 哈哈， r528资料太少，网上一搜就这点东西。萌新坐了一个月的牢终于解放了
-
R528跟T113差不多，基本参考它就行。
LVDS好搞，如果参数不行，把分辨率改了后，直接用以前OK的时序先顶上调调看。 -
@hqembed RGB屏幕换成LVDS只需要修改设备树吗？我的设备树参数是对的但就是点不亮，不知道是不是tina-linux有什么别的机制还是有什么Bug，文档里也没说
-
对的，改default_lcd就行了，我贴几个验证过的lvds屏你参考下

@hqembed 谢谢大佬

@goodwill1945 不是吧，有这么巧的吗，如果确实是的，那我留下了调试笔记，照着来问题不大的呢，r528走之前LVDS是整完了的。

@hqembed 试了两个参数，亮了两个屏，参数应该都是准的，厉害
