@大法师 The latest ubuntu22.04 image can already support this camera.

20230210-ubuntu-22.04-preinstalled-desktop-arm64-coolpi.rar

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

Can you provide an android 12 image with wifi support?

@jack_admin I mean can output video signal on the gpio using with custom timings, like you can on the RPI4?

补充内核编译操作说明（如下以coolpi 4b ubuntu22.04 0306系统版本为例）：

首先下载内核源码

coolpi@coolpi:~$ git clone https://github.com/yanyitech/coolpi-kernel.git Cloning into 'coolpi-kernel'... remote: Enumerating objects: 8550563, done. remote: Counting objects: 100% (5962/5962), done. remote: Compressing objects: 100% (3084/3084), done. remote: Total 8550563 (delta 2757), reused 5819 (delta 2648), pack-reused 8544601 Receiving objects: 100% (8550563/8550563), 1.98 GiB | 11.07 MiB/s, done.

额外安装组件包

coolpi@coolpi:~$ sudo apt install -y flex bison libssl-dev coolpi@coolpi:~$ sudo ln -sf /usr/bin/python3 /usr/bin/python

开始编译内核

coolpi@coolpi:~$ cd coolpi-kernel coolpi@coolpi:~/coolpi-kernel$ ./build-kernel.sh cp4b

@myhexb 联系一下代理商，申请售后。

@顾真牛 @大法师 感谢你们的帮助🤓

coolpi/coolpi is the username and password for the debian build. people need to do a better job of documenting on this forum.
