1. 概述
ARS-MB-B1是正旗通信推出的新一代嵌入式WiFi主板，采用瑞芯微RK3568高性能处理器。本文给出搭建RK3568 OpenWRT开发环境的方法，此开发环境基于OpenWRT 23.05及瑞芯微Linux Kernel 5.10.160构建。
2. 准备工作
(1) 安装Ubuntu 22.04 LTS 64位版本，操作系统安装指导请参照https://ubuntu.com/tutorials/install-ubuntu-desktop。
(2) 更新系统软件，运行以下命令：
sudo apt update -y
sudo apt full-upgrade -y更新后重新启动系统。
(3) 安装编译OpenWRT所需要的软件，运行以下命令：
sudo apt install -y ack antlr3 asciidoc autoconf automake autopoint binutils bison \
build-essential bzip2 ccache clang cmake cpio curl device-tree-compiler flex gawk \
gcc-multilib g++-multilib gettext genisoimage git gperf haveged help2man intltool \
libc6-dev-i386 libelf-dev libfuse-dev libglib2.0-dev libgmp3-dev libltdl-dev libmpc-dev \
libmpfr-dev libncurses5-dev libncursesw5-dev libpython3-dev libreadline-dev libssl-dev \
libtool llvm lrzsz msmtp ninja-build p7zip p7zip-full patch pkgconf python3 python3-pyelftools \
python3-setuptools qemu-utils rsync scons squashfs-tools \
subversion swig texinfo uglifyjs upx-ucl unzip vim wget xmlto xxd zlib1g-dev3. 搭建OpenWRT编译环境
(1) 确保Ubuntu可以正常访问github.com。
(2) 使用普通用户登录Ubuntu系统，如lics，在/home/lics目录下创建data/share及data/code目录，其中data/share为共享目录，可以通过Windows访问，data/code为源代码存放目录。
(3) 将我司提供的rkwrt_2305_ars-mb-b1.tar.gz复制到~/data/share目录下，然后运行以下命令：
tar -zxvf rkwrt_2305_ars-mb-b1.tar.gz -C ./
cp rkwrt_2305_ars-mb-b1/rkwrt_2305_init.sh ~/data/code
cd ~/data/code
./rkwrt_2305_init.sh接下来请耐心等待编译完成。
(4) 编译完成后请输入以下命令：
cp rkwrt_2305/bin/targets/rockchip/armv8/ARS-MB-B1_RKWRT_2305_20250513.zip ~/data/share其中20250513为当天的日期，会随着日期变化。
(5) 将编译得到的ARS-MB-B1_RKWRT_2305_20250513.zip复制到Windows中，解压，烧录至eMMC或者TF卡，ARS-MB-B1即可正常运行，如下图
