米文AD10配置gmsl摄像头操作

一、进入桌面快捷方式

0、设置摄像头型号

miivii_websettings.desktop
设置摄像头

1、获取camera信息

cat /var/log/gmsl_camera.log

nvidia@miivii-tegra:~$ cat /var/log/gmsl_camera.log
attestationVerify [13] succeed.
[INFO ]: miivii gmsl service start!
[INFO ]: VIDEO0 = sensing_OX01F10C
[INFO ]: VIDEO1 = none
[INFO ]: VIDEO2 = none
[INFO ]: VIDEO3 = sensing_ar0820
[INFO ]: VIDEO4 = none
[INFO ]: VIDEO5 = none
[INFO ]: VIDEO6 = none
[INFO ]: VIDEO7 = none
[INFO ]: gmsl camera init cnt = 0
[INFO ]: sys power off
[INFO ]: sys power on
[INFO ]: Init:a-2, dev_node = video0 ...
[INFO ]: Init:a-1, dev_node = video1 ...
[INFO ]: Init:b-2, dev_node = video2 ...
[INFO ]: Init:b-1, dev_node = video3 ...
[INFO ]: Init:c-2, dev_node = video4 ...
[INFO ]: Init:c-1, dev_node = video5 ...
[INFO ]: Init:d-2, dev_node = video6 ...
[INFO ]: Init:d-1, dev_node = video7 ...
[INFO ]: cam init is successful!
nvidia@miivii-tegra:~$ 

2、运行摄像头

//使用gst-launch打开
gst-launch-1.0 -v v4l2src device="/dev/video0" ! video/x-raw,width=1280,height=720,format=UYVY ! xvimagesink
gst-launch-1.0 -v v4l2src device="/dev/video3" ! video/x-raw,width=3840,height=2160,format=UYVY ! xvimagesink
//使用opencv高清摄像头会启不起来
/opt/miivii/features/gmsl_camera/bin/cameras_opencv_demo -s 3840x2160 -d /dev/video3
/opt/miivii/features/gmsl_camera/bin/cameras_opencv_demo -s 1280x720 -d /dev/video0
//使用sdk高清摄像头会启不起来
/opt/miivii/features/gmsl_camera/bin/cameras_sdk_demo -s 3840x2160 -d /dev/video3
/opt/miivii/features/gmsl_camera/bin/cameras_sdk_demo -s 1280x720 -d /dev/video0

3、重新设置root密码

sudo passwd root
//进入root用户
su root

4、查看gmsl摄像头使用状态

root@miivii-tegra:/home/nvidia# systemctl status | grep gmsl│   │ │   │ └─300573 /opt/miivii/features/gmsl_camera/bin/cameras_opencv_demo -s 1280x720 -d /dev/video0│   │ │   │ └─351959 grep --color=auto gmsl│   │ │   │ └─307061 /opt/miivii/features/gmsl_camera/bin/cameras_opencv_demo -s 3840x2160 -d /dev/video3│ ├─  1888 /usr/local/bin/miivii_gmsl2_service

5、摄像头初始化

root@miivii-tegra:/usr/local/bin# ./miivii_gmsl2_service 
attestationVerify [2] succeed.
[INFO ]: miivii gmsl service start!
[INFO ]: VIDEO0 = sensing_OX01F10C
[INFO ]: VIDEO1 = none
[INFO ]: VIDEO2 = none
[INFO ]: VIDEO3 = sensing_ar0820
[INFO ]: VIDEO4 = none
[INFO ]: VIDEO5 = none
[INFO ]: VIDEO6 = none
[INFO ]: VIDEO7 = none
[INFO ]: gmsl camera init cnt = 0
[INFO ]: sys power off
[INFO ]: sys power on
[INFO ]: Init:a-2, dev_node = video0 ...
[INFO ]: Init:a-1, dev_node = video1 ...
[INFO ]: Init:b-2, dev_node = video2 ...
[INFO ]: Init:b-1, dev_node = video3 ...
[INFO ]: Init:c-2, dev_node = video4 ...
[INFO ]: Init:c-1, dev_node = video5 ...
[INFO ]: Init:d-2, dev_node = video6 ...
[INFO ]: Init:d-1, dev_node = video7 ...
[INFO ]: cam init is successful!

6、检测I2C总线上连接的设备

0123共用一个9296解串器

nvidia@miivii-tegra:~$ i2cdetect -r -y 20  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- UU UU UU UU UU UU -- -- -- -- -- -- 
10: UU UU -- -- -- -- -- -- -- -- -- -- -- -- -- --
