MIPI单通道屏调试过程及问题整理

gufengdianxia · 发表于 2015-2-12 19:17:34

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 <okay>

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:}

gufengdianxia · 发表于 2015-2-15 10:34:03

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？

系统没有你这个分辨率的资源，得自己修改。systemui里面的

需要如何修改？我是修改了DPI后显示正常

zhansb · 发表于 2015-2-13 09:22:16

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

暴走的阿Sai · 发表于 2015-2-13 09:26:51

总结是个好习惯

gufengdianxia · 发表于 2015-2-15 13:56:25

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。

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 · 发表于 2015-6-29 14:01:22

系统没有你这个分辨率的资源，得自己修改。systemui里面的

suky8 · 发表于 2015-6-29 17:22:49

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？
