标题: RK3288 PAD版使用单MIPI屏
请教各位大神一个问题：
使用MIPI TX/RX接单MIPI屏，按照社区上下载的PAD版本的SDK中，
#include "lcd-ld089wu1-mipi.dtsi"
然后再使用有碰到几个问题：
1、rockchip,cmd：这个设置的值长度超过27个的时候，软件编译没问题，但是烧入到机器中机器会死机，这个参数长度有限制吗？
2、使用MIPI屏了，他这里应该是单独的了吧，这个主显是不是就空了？：
/*lcdc0 as PRMRY(LCD),lcdc1 as EXTEND(HDMI)*/
&lcdc0 {
status = "okay";
rockchip,mirror = <NO_MIRROR>;
rockchip,cabc_mode = <0>;
power_ctr: power_ctr {
rockchip,debug = <0>;
lcd_en:lcd_en {
rockchip,power_type = <GPIO>;
gpios = <&gpio7 GPIO_A3 GPIO_ACTIVE_HIGH>;
rockchip,delay = <10>;
};

lcd_cs:lcd_cs {
rockchip,power_type = <GPIO>;
gpios = <&gpio7 GPIO_A4 GPIO_ACTIVE_HIGH>;
rockchip,delay = <10>;
};

/*lcd_rst:lcd_rst {
rockchip,power_type = <GPIO>;
gpios = <&gpio3 GPIO_D6 GPIO_ACTIVE_HIGH>;
rockchip,delay = <5>;
};*/

};
};

&lcdc1 {
status = "okay";
rockchip,mirror = <NO_MIRROR>;
};

第一个问题：目前SDK是有这样的限制，可以修改驱动支持更长的指令数目，比如：

第二个问题：还是用的是主显啊，使用lcdc0

哦果然有限制啊我试试谢谢！

版主：
目前MIPI屏这边我还没有点亮，但是我更改#include "lcd-ld089wu1-mipi.dtsi"的屏的参数，HDMI输出的效果会发生变化呢？按道理他们是双路LCDC的，HDMI走LCDC1，按您说的 MIPI走LCDC0，那应该不会影响到HDMI的输出显示才对，这是为什么呢？

作者: zhansb 时间: 2015-1-21 10:37
因为PAD版中HDMI是根据LCD屏做scale的，只要分辨率改动了，就会影响到HDMI

作者: tangyu1121 时间: 2015-1-21 11:12
那这样应该还有个scaler能将HDMI还原成正常的显示吧？

作者: zhansb 时间: 2015-1-21 11:14
如果要照顾到HDMI的显示，那应该要把分辨率设置成电视同比例的分辨率了

作者: tangyu1121 时间: 2015-1-21 17:08
接单MIPI屏不能使用MIPI TX/RX通道，使用单MIPI屏只能接MIPI TX通道！！！！！

还没有，硬件有点问题，做的排线是连到MIPI TX/RX这个复用的同路去了，客户这2会重新弄一个双MIPI的屏来点，等他们硬件弄好了，在点了

目前的问题就是单MIPI的屏接到MIPI TX/RX通路去了，所以他们想直接调试双MIPI通道的了，等他们硬件整好我这边在烧入软件看看，有什么问题在请教你啦

版主点双MIPI屏需要连一个RST脚，你们点的时候连的是哪个脚啊？

版主：

您好！
我现在在点双MIPI屏的时候碰到一个问题：按照文档中的配置好了双MIPI屏的参数，开机在串口中显示：
rk3288-lcdc lcdc0: blank mode:0 屏没有显示
这个是什么情况：
我的更改：
LCD Panel Select (rk mipi dsi lcd) --->

Rockchip MIPI DSI support
<*> rk32 mipi dsi support
arch/arm/boot/dts/rk3288.dtsi中将
dsihost0 和 dsihost1 的status 都设置为：okay
firefly-rk3288.dts中包含屏部分的配置
#include "lcd-ld089wu1-mipi.dtsi"

作者: zhansb 时间: 2015-1-23 19:20
可以查查：
1.lcd的电源、控制引脚的时序
2.屏的时序，比如hbp,vbp...
3.MIPI指令是否正确
4..config中是否这三个都有配上
+CONFIG_LCD_MIPI=y
+CONFIG_MIPI_DSI=y
+CONFIG_RK32_MIPI_DSI=y
5.背光亮了吗

作者: zhansb 时间: 2015-1-23 19:24
控制引脚可以在arch/arm/boot/dts/firefly-rk3288.dts中修改：

675 lcd_en:lcd_en {
676 rockchip,power_type = <GPIO>;
677 gpios = <&gpio7 GPIO_A3 GPIO_ACTIVE_HIGH>;
678 rockchip,delay = <10>;
679 };
680
681 lcd_cs:lcd_cs {
682 rockchip,power_type = <GPIO>;
683 gpios = <&gpio7 GPIO_A4 GPIO_ACTIVE_HIGH>;
684 rockchip,delay = <10>;
685 };
686
687 /*lcd_rst:lcd_rst {
688 rockchip,power_type = <GPIO>;
689 gpios = <&gpio3 GPIO_D6 GPIO_ACTIVE_HIGH>;
690 rockchip,delay = <5>;
691 };*/

你好！
1.lcd的电源、控制引脚的时序
LCD_EN是硬件直接拉高的，软件没孔控制
2.屏的时序，比如hbp,vbp...
这个和屏参确认过，参数是正确的；
3.MIPI指令是否正确
指令也和屏厂确认过
4..config中是否这三个都有配上
+CONFIG_LCD_MIPI=y
+CONFIG_MIPI_DSI=y
+CONFIG_RK32_MIPI_DSI=y
这3个已经是打开的
5.背光亮了吗
屏厂的意思是用LED灯照屏的背面能看到图像显示的

现在关键是配置完以后：
rk3288-lcdc lcdc0: blank mode:0 屏没有显示
主显没有图像输出，可能的原因是什么啊？

这个没什么关系，这个对应的是SCREEN_NULL

双MIPI的话把rockchip,dsi_id = <0>;这个改成rockchip,dsi_id = <2>;

HI 屏参这块就寄存器的值和IO的区别，您是否可以将你那边点这个双MIPI屏的整个更改的PATCH上传我看下，我看下是否是我哪里没有更改到，我目前的更改都是按照RockChip_DSS Development Guide v1.2.pdf 这个文档里面说的配置来更改的！

HI 更改的地方好我这边更改的基本是相同的！
我们现在硬件测量输出的CLK信号没有，按正常的情况，应该软件配置了MIPI输出应该CLK信号就能测量到的吧？
您有没有加入QQ群，能否发一个您使用的kernel固件给我，我烧入测量一下CLK是否有，我在QQ群的名字是：冬冬

晕我也是闲着 mipi设置好了 clk没有输出，而且屏幕直显示一半

我将rockchip,screen_init = <0>; 中的0改为1时,系统就会停在kernel进入的界面
