初用鲁班猫切换屏幕为MIPI-1080P

鲁班猫信息:
板卡从如下地址采购:.htm?_u=110jcean66aa&id=694560455663&spm=a1z09.2.0.0.56f52e8dj4eUdI&skuId=5156903694777
鲁班猫官方文档和教程:.html
视频教程:=1352573
板子实物图如下:

烧录鲁班猫镜像
按照视频教程的说法这里使用EMMC烧录镜像,选择如下镜像:
E:\Study\鲁班猫\3-Linux镜像\Debian系统镜像\通用镜像(extboot)-适用于所有板卡\20230712\LubanCat-rk3566\lubancat-rk3566-debian10-xfce-20230712_update\lubancat-rk3566-debian10-xfce-20230712_update.img
注意:先短路MR点,再重新上电,这时候软件能够识别到MASKROM设备(如上图),然后再断开MR点,再点击升级按钮进行烧录
镜像烧录成功后可以看到下面的打印说明系统运行起来了,但是因为默认的屏幕使用的是HDMI的,而我们接的屏幕是MIPI的,所以我们看不到显示:

这里用串口登录系统

修改屏幕为MIPI
输入"fire-config"命令进入配置界面:

进入屏幕配置:


这里选择1080P:
注意:这里使用空格键进行切换(请看如下说明:.html)

选择finish并且退出,然后输入"reboot"命令重启:


可以看到屏幕正常显示了:

鲁班猫修改屏幕适配MIPI

旋转屏幕为横屏显示

但是现在屏幕是竖屏的,我们的使用习惯是横屏的,进入系统,输入如下命令:
“xrandr --output DSI-1 --rotate left”

可以看到屏幕变成了我们想要的横屏

但是这里发现触摸异常了

鲁班猫触摸异常

这里通过"fire-config"来修改触摸方向:


向左旋转90度:

选择finish推出后可以看到屏幕恢复正常:

鲁班猫触摸正常

屏幕和触摸方向修改永久保存

但是我测试发现这种方式在下次重启的时候又恢复成原来的竖屏了,这里要找到能够保存屏幕设置的方法才行!
按照鲁班猫官方的说法要解决这个问题就是开启一个自启动服务,这个服务去修改屏幕的方向,虽然我觉得这个不是最正宗的办法,后来根据官方的提醒修改"/etc/X11/xorg.conf.d/20-modesetting.conf"文件实现永久修改屏幕和触摸方向,修改后的"20-modesetting.conf"文件如下:

root@lubancat:~# cat /etc/X11/xorg.conf.d/20-modesetting.conf   
Section "Device"Identifier  "Rockchip Graphics"Driver      "modesetting"### Use Rockchip RGA 2D HW accel
#    Option      "AccelMethod"    "exa"### Use GPU HW accelOption      "AccelMethod"    "glamor"Option      "DRI"            "2"### Set to "always" to avoid tearing, could lead to up 50% performance lossOption      "FlipFB"         "none"### Limit flip rate and drop frames for "FlipFB" to reduce performance lost
#    Option      "MaxFlipRate"    "25"Option      "NoEDID"         "true"
EndSectionSection "Screen"Identifier  "Default Screen"Device      "Rockchip Graphics"Monitor     "Default Monitor"
EndSection### Valid values for rotation are "normal", "left", "right"
Section "Monitor"Identifier  "Default Monitor"Option      "Rotate" "left"
EndSectionSection "InputClass"Identifier "Goodix Capacitive TouchScreen"MatchProduct "Goodix Capacitive TouchScreen"Option "TransformationMatrix" " 0 -1 1 1 0 0 0 0 1 
EndSection

其中"Monitor"修改了屏幕的方向,"InputClass"修改了触摸的方向,实现效果其实和这两句话一样:

xrandr --output DSI-1 --rotate left
xinput set-prop 9 'Coordinate Transformation Matrix' 0 -1 1 1 0 0 0 0 1

最终效果如下:

鲁班猫屏幕和触摸永久保存

这里还有一个问题,就是开机的时候log会输出到屏幕上,经过上面的修改后桌面的屏幕是反过来了,但是打印log的时候屏幕还没有反,这里修改"/boot/uEnv/uEnv.txt"文件如下:

uname_r=4.19.232
size=0x1000000
cmdline="earlyprintk console=ttyFIQ0 console=tty1 fbcon=rotate:3 consoleblank=0

"/boot/uEnv/uEnv.txt" 51L, 2575C written        

这里主要是增加了内容"fbcon=rotate:3"
最终效果如下:
