      @大法师 建议尽快支持一下树莓派的HQ Camera,传感器型号是IMX477R,现在这款摄像头很火,可以匹配各种不同的镜头。IMX708支持自动对焦,是新出的产品。

      Is the the type-c PD port also a USB-c data port

      Sorry,This port is used for power supply and has no data connection.

      大法师

      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. Resolving deltas: 100% (7166058/7166058), done. Checking objects: 100% (33554432/33554432), done. Updating files: 100% (87196/87196), done. coolpi@coolpi:~$

      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
