@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。

Welcome to OpenEmbedded, the build framework for embedded Linux. OpenEmbedded offers a best-in-class cross-compile environment. It allows developers to create a complete Linux Distribution for embedded systems. Some of the OpenEmbedded advantages include:

adopted as the build system for the Yocto Project in March 2011.

support for many hardware architectures

multiple releases for those architectures

tools for speeding up the process of recreating the base after changes have been made

easy to customize

runs on any Linux distribution

cross-compiles 1000's of packages including GTK+, Qt, the X Windows system, Mono, Java, and about anything else you might ever need

step1:
git clone https://gitee.com/yanyitech/openwrt.git cd openwrt ### Quickstart 1. Run `./scripts/feeds update -a` to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default 2. Run `./scripts/feeds install -a` to install symlinks for all obtained packages into package/feeds/ 3. Run `make menuconfig` to select your preferred configuration for the toolchain, target system & firmware packages. 4. Run `make` to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

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
