标题: 请教：点10.1寸单路lvds屏
各位好。

我现在在点一个10.1的lvds屏，单路的，分辨率是1024x600；我用的板子是firefly3288 reload。
代码是5.1的（也同步到wiki的最新的了）；

这个屏用我改动的代码（主要改动了dst文件和对应的屏的dtsi文件），编译出来的映像，一直没有点亮，只有背光亮了，屏也不花；也没找到问题所在；

我在论坛上找到了天启发布的点亮10.1寸lvds 屏的映像；里面有编译好的映像和补丁；时间是20161227左右的；
以下的这个链接：
http://wiki.t-firefly.com/index. ... A.E6.A8.A1.E7.BB.84

对应的百度网盘：
https://pan.baidu.com/s/1c9rDSy

于是我把里面编译好的支持10.1寸lvds屏的那个固件（即那个链接里面的那个），更新进去板子，接上我的lvds屏，发现屏能点亮了，只是分辨率没对上；

接着我做了一下替换尝试，先把板子的kernel.img 换为我自己编译的；这样后，板子能点亮我的lvds屏；

接着替换resource.img，替换后，发现屏不能正常亮了；

我想，问题大概出在resource.img中，即相关的资源文件，如dst.屏的dtsi等（这里屏的dtsi我用的是代码中的lcd-b101ew05.dtsi）；

但我手头上没有能确保是能正常点亮这屏的资源文件，我想，有哪位能否发一下你们那边编译那个支持lvds屏时用到资源文件给我，让我去对比一下呢。
或者给一些建议，看看是我的dst文件或dtsi文件哪里出问题了？

（对于链接中提到的补丁，我也尝试过打上去了，没起作用；）

谢谢；

屏对应的dtsi文件，我现在直接用源码中的lcd-b101ew05.dtsi 文件，分辨率也没做改动，想着先看看是否能点亮；（因为上面我直接用了天启编译出来的固件能够点亮我的lvds屏，它用的就是 lcd-b101ew05.dtsi  文件）

点亮LVDS屏幕这么麻烦么，不能像其他开发板一样直接通过SD卡配置参数么

作者: vinsionLeo 时间: 2017-8-21 09:38
请问你的问题解决了吗？我点lvds屏也遇到了这样的问题，应该要怎么改呢？
