 参考这里 \url{https://embedded.pages.openeuler.org/master/introduction/index.html}，把主要步骤记录一下。

-\section{制作 Rk3588 镜像和 SDK}
+\subsection{创建安装目录}

 oebuild init yocto-oebuild -b openEuler-24.03-LTS
 cd yocto-oebuild
 oebuild update

+\section{制作 Rk3588 镜像和 SDK}

+\subsection{添加客户要求软件}
+编辑 ``build/rk3588/compile.yaml'' ， 在 ``local.conf:'' 下面添加必要软件，如下示例：
+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}
+local_conf: |
+  INIT_MANAGER = "systemd"
+  VIRTUAL-RUNTIME_dev_manager = "systemd"
+  IMAGE_INSTALL:append = "tcpdump ethtool iperf2 bridge-utils minicom"
+
+  PREFERRED_PROVIDER_virtual/kernel ?= "linux-openeuler"
+\end{minted}
+
+其中 ``IMAGE\_INSTALL:append'' 是新增的内容。
+
+\subsection{编译镜像文件}
+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}
+cd build/rk3588
 oebuild bitbake openeuler-image
 oebuild bitbake openeuler-image -c do_populate_sdk
 \end{minted}
+
+\subsection{问题处理}
+
+\begin{enumerate}[(1)]
+    \item {ERROR - ERROR: tcpdump-4.99.3-r0 do\_fetch: Bitbake Fetcher Error: FetchError(`Unable to fetch URL from any source.', `file://tcpdump-4.99.3.tar.gz')}
+
+    先用下面命令下载文件：
+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}
+cd yocto-oebuild/src/yocto-meta-openembedded/meta-networking/\
+    recipes-support/tcpdump/tcpdump
+wget -c http://www.tcpdump.org/release/tcpdump-4.99.3.tar.gz
+wget -c https://gitee.com/src-openeuler/tcpdump/raw/master/\

+\end{minted}
+
+然后修改 ``\texttt{yocto-oebuild/src/yocto-meta-openeuler/meta-\\%
+openeuler/dynamic-layers/networking-layer/recipes-support\\%
+/tcpdump/tcpdump\_\%.bbappend}'' 文件中的 ``SRC\_URI[md5sum]'' 和
