MIPI单通道屏调试过程及问题整理

[gufengdianxia]

本人小菜，写这些过程及问题主要目的就是想请教大神，其次也是想为和我一样的MIPI调屏新手开辟一条更直观的路。
正好官网有DSI的调试教程，马上搞起！:lol

MIPI屏的基本信息为：分辨率为480x854 单通道2 lane屏本身OK，因为可以用单片机板子点亮OK

按MIPI DSI的调试步骤来设置：

1.配置/kernel/arch/arm/configs/firefly-rk3288_defconfig

2./kernel/arch/arm/boot/dts/下新增配置文件
lcd-swi045-mipi.dtsi
部分代码贴上（完整的在附件中）

3./kernel/arch/arm/boot/dts/firefly-rk3288.dts下添加DST文件

修改lcd_rst的GPIO配置

4.由于是单通道，/kernel/arch/arm/boot/dts/rk3288.dtsi中配置dsihost0

5.连线（）

编译烧录后发现屏无任何反应，应该是初始化都没有成功{:3_47:}
呼唤zhangsb大神，代码上是否哪里存在问题？{:3_59:}

Code.rar (2.59 KB)

cmd的第一个字节DSI数据类型没有写上去，还有没看到背光的配置

[_Sai]

总结是个好习惯

[gufengdianxia]

背光我暂时没有配置，因为背光我是外供的，所以不会出现无背光的情况。
另外DSI数据类型是什么？我只有LCM的Initial，如何与DSI数据类型对应起来？

[gufengdianxia]

zhangsb大神，我有看到Data Type主要分为Generic xx write和DCS xx write。

以0x29和0x39为例，这两种Data Type在是使用的时候有什么区别么？

以上为dtsi的配置。另外我试着抓出fb0中的图片，发现其分辨率变为480x800。

仔细查找发现原来timing设置中把480x854竖屏写成了横屏{:3_47:}。。。

改完后抓出来的图片分辨率就是480x854了。。。。

发现已经有闪烁的迹象了，但是还是没显示。由于数据线都是用跳线形式，猜想会不会是因为速率太快使信号丢失了？
继续改{:3_46:}

将dsi_hs_clk改为500M
继续编译烧写固件
奇迹出现啦，虽然有问题，但是有画面啦~~~~{:3_59:}

既然屏已经点亮，系统的问题还是另开新帖再问大神吧~~~~~
希望对大家有一些帮助~~~

請教一下,dsi_hs_clk的設定是如何得知的?

[carlinluo]

系统没有你这个分辨率的资源，得自己修改。systemui里面的

[suky8]

请问你是用的那个源码：是普通版的，还是PAD版的，有用官方提供的更新操作么？

源吗是用的普通还是PAD的。根据这个文档中：http://wiki.t-firefly.com/index.php/Firefly-RK3288/Build_android 中提到的 更新操作：git clone -b firefly/master git://git.us.linux-rockchip.org/rk3288_r-box_android4.4.2_sdk.git你这边有做么？我也在研究这个MIPI接口，可惜一直都没有亮

这里面只有一些dts的配置吧，初始化休眠之类的都不需要？

请问楼主用pad版本的，添加文件步骤相同，最后没有信号输出是怎么回事啊，好像进入什么睡眠模式，要怎么办？

需要如何修改？我是修改了DPI后显示正常

gufengdianxia你好,

想请问你DPI是在哪修改的?

我现在这边有一块320x480的3.5吋的屏幕, 目前也还没点出画面…
