coolpi 4b support ov5647 camera module
-
-
@大法师 没有。dev 下无vido 。dmesg 运行无响应。
-
@bg8wj 需要更新内核驱动
-
@大法师 刷入提供的最新的ubuntu20.04 执行dmesg

另最新的20.04 ros2 opencv miniconda 安装正常了 -
@bg8wj github已更新内核驱动代码。二进制执行文件明天测试好再上传

@大法师 Hi, thanks for your effort!
A suggestion, why not doc your work as a tutorial?
So that everyone can help you debug the code. -
@大法师 非常感谢。麻烦您。如可以给个安装指导。我汇总成教程。coolpi 4b 非常强大，我再学习移植一些 raspbeery 4b的项目到coolpi上。
-
@bg8wj 谢谢！我们验证好了会同步发布出来。这款主板还有很多功能可以挖掘，需要更多的伙伴一起共赢！

暂时未重新打包刷机镜像，可以先独立更新内核驱动包。
coolpi@coolpi:~$ sudo dpkg -i coolpi-kernel_1.0.0_aarch64.deb coolpi@coolpi:~$ sync coolpi@coolpi:~$ sudo reboot重启系统，如有连接ov5647摄像头，可以识别到video设备。
coolpi@coolpi:~$ sudo apt install v4l-utils coolpi@coolpi:~$ v4l2-ctl --list-devices rkisp-statistics (platform: rkisp): /dev/video18 /dev/video19 rkcif (platform:rkcif-mipi-lvds2): /dev/video0 /dev/video1 /dev/video2 /dev/video3 /dev/video4 /dev/video5 /dev/video6 /dev/video7 /dev/video8 /dev/video9 /dev/video10 rkisp_mainpath (platform:rkisp0-vir0): /dev/video11 /dev/video12 /dev/video13 /dev/video14 /dev/video15 /dev/video16 /dev/video17 -

請問是否有機會支援 VEYE 系列的模組？ 像是 IMX462 之類 （http://www.veye.cc/产品/veye-mipi-imx462-2/#tab-id-2）
畢竟 VEYE 也是國產之光，國內也比較容易買得到

Hi, I tried the new kernel with two OV5647 camera.
It looks the default configuration is not correct.
The command I usedsudo v4l2-ctl --verbose -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat='NV12' --stream-mmap=4 --set-selection=target=crop,flags=0,top=0,left=0,width=1920,height=1080 --stream-to=out1.yuv ffplay out1.yuv -pixel_format nv12 -video_size 1920x1080The system message

ubuntu or armbian version need verify and then release. -
@大法师 The latest ubuntu22.04 image can already support this camera.
-

-
V4L2-TEST can start the camera by operating the video11 node
