一、目标
本篇的目标是 使用 Buildroot 的 BR2_EXTERNAL 功能创建一个我们自己的 bsp 板子， 名字叫做 lotus.
使用 qemu 跑 linux5.4x
1.1 BR2_EXTERNAL 介绍
BR2_EXTERNAL 是 Buildroot 提供的一个强大机制，它允许你将自定义的配置、软件包、内核配置、板级支持等与官方的 Buildroot 代码树完全分离开。这样做的好处非常明显：
隔离与维护：你的项目特定文件不会被污染，易于管理和版本控制（例如，可以放在独立的 Git 仓库中）。
复用与升级：你可以轻松地切换或升级 Buildroot 的版本，而无需修改或移动你的项目文件。只需在编译时指向你的外部树路径即可。
结构清晰：强制形成一个清晰、规范的项目结构。
二、创建一个lotus的工程
2.1 在git仓库里面创建项目结构
这个不用多说了， 都会哈。
git clone https://gitee.com/xxx/lotus_bsp.git
cd lotus_bsp
1. 初始化主项目 Git 仓库
# 初始化Git仓库
git init
# 创建.gitignore文件，忽略不必要的文件
cat > .gitignore << 'EOF'
# Buildroot输出目录
/buildroot/output/
# 镜像输出目录
/images/
# 编辑器文件
*.swp
*~
.*.swp
.*.un~
# 临时文件
*.tmp
*.log
# 备份文件
*.bak
*.old
# 编译生成的文件
*.o
*.a
*.so
*.d
*.deps
EOF
# 添加初始文件并提交
git add .
git commit -m "Initial commit: Lotus project structure"
2.添加 Buildroot 作为子模块
# 删除之前手动克隆的buildroot目录（如果存在）
rm -rf buildroot
# 添加Buildroot作为子模块
git submodule add https://git.buildroot.net/buildroot buildroot
# 初始化并更新子模块
git submodule update --init --recursive
3. 配置子模块相关设置
1.创建子模块配置文件
# 创建.gitmodules文件（通常由git submodule add自动生成，但我们可以自定义配置）
cat > .gitmodules << 'EOF'
[submodule "buildroot"]
path = buildroot
url = https://git.buildroot.net/buildroot
branch = master
EOF
2. 创建子模块管理脚本
# 创建一个脚本用于方便地更新子模块
cat > update_submodules.sh << 'EOF'
#!/bin/bash
echo "Updating Buildroot submodule..."
git submodule update --init --recursive
echo "Checking out Buildroot stable branch..."
cd buildroot
git checkout $(git describe --tags --abbrev=0)
echo "Buildroot submodule updated to latest stable release."
EOF
chmod +x update_submodules.sh
3. 创建项目文档说明
# 创建README文件说明项目结构
cat > README.md << 'EOF'
# Lotus Project
基于Buildroot的嵌入式Linux项目。
4. 提交完成子模块配置
# 添加子模块相关文件
git add .
git add .gitmodules
git add buildroot # 这实际上添加的是对子模块commit的引用
# 提交子模块配置
git commit -m "Add Buildroot as submodule"
4. 子模块管理
更新到最新稳定版：
./update_submodules.sh查看子模块状态：
git submodule status更新子模块：
git submodule update --remote
5.创建实用的 Git 钩子和脚本
1. 创建克隆后初始化脚本
mkdir -p scripts
cat > scripts/setup_project.sh << 'EOF'
#!/bin/bash
echo "Setting up Lotus project..."
# 确保子模块初始化
if [ ! -d "buildroot/.git" ]; then
echo "Initializing Buildroot submodule..."
git submodule update --init --recursive
fi
# 检查Buildroot版本
cd buildroot
BUILDROOT_VERSION=$(git describe --tags --abbrev=0)
echo "Buildroot version: $BUILDROOT_VERSION"
# 创建images目录如果不存在
cd ..
mkdir -p images
echo "Project setup complete!"
EOF
chmod +x scripts/setup_project.sh
2. 创建 Git 钩子确保子模块状态
mkdir -p .githooks
cat > .githooks/post-merge << 'EOF'
#!/bin/bash
# 在merge后自动更新子模块
echo "Updating submodules after merge..."
git submodule update --init --recursive
EOF
chmod +x .githooks/post-merge
# 配置Git使用自定义钩子目录
git config core.hooksPath .githooks
6. 创建项目结构
# 在 lotus_bsp 目录下创建
mkdir buildroot_external images
# 创建 BR2_EXTERNAL 所需的目录结构
mkdir -p buildroot_external/{board/lotus,configs,package/helloworld/src}
最终的项目结构确认
lotus_bsp/
├── .git/ # Git仓库数据
├── .githooks/ # Git钩子
│ └── post-merge
├── buildroot/ # Buildroot子模块
├── buildroot_external/ # 我们的外部项目树 (BR2_EXTERNAL)
│ ├── board/lotus/ # lotus板级支持包
│ ├── configs/
│ ├── package/helloworld/ # 自定义helloworld软件包
├── images/ # 存放最终镜像
├── scripts/ # 实用脚本
│ └── setup_project.sh
├── .gitignore # .gitignore忽略
├── .gitmodules
├── README.md
└── update_submodules.sh
7. 如何使用这个仓库
1. 克隆项目（对于其他开发者）
# 递归克隆（推荐）
git clone --recursive <your-repository-url> lotus_bsp
cd lotus_bsp
# 或者如果已经克隆，初始化子模块
git submodule update --init --recursive
2. 日常开发工作流
# 1. 更新子模块到最新稳定版本
./update_submodules.sh
# 2. 进行开发修改
# 修改 buildroot_external/ 中的文件
# 3. 提交更改
git add .
git commit -m "Update lotus board configuration"
# 4. 如果需要更新Buildroot版本
cd buildroot
git checkout 2024.02.1 # 切换到特定版本
cd ..
git add buildroot
git commit -m "Update Buildroot to 2024.02.1"
3. 查看子模块状态
# 查看子模块状态
git submodule status
# 查看子模块的远程更新
cd buildroot
git fetch
git log --oneline HEAD..origin/master
cd ..
4.重要的 Git 命令参考
# 更新子模块到远程最新
git submodule update --remote
# 查看子模块差异
git diff --submodule
# 进入子模块进行开发
cd buildroot
git checkout -b feature-branch
# 进行修改...
git commit -a -m "Buildroot changes"
cd ..
git add buildroot
git commit -m "Update Buildroot submodule reference"
这样的配置确保了：
版本控制：主项目和Buildroot都有明确的版本管理
可重复构建：任何人都能获得完全相同的开发环境
易于维护：清晰的子模块管理策略
团队协作：标准的Git工作流程
8. 选择 buildroot 的版本
我们的目标是 使用 qemu 跑arm64 linux 5.4.x 的内核。
根据 Buildroot版本与Linux内核调试对应关系的介绍，我们这里选择 Buildroot 2020.02.9 版本。 根据我实际的测试发现 该版本 qemu 编译上有点问题， 但是这些问题在 2020.05.1
有解决， 所以我最终选择了 2020.05.1
leo@leo ~/data_4t/github/lotus_bsp/buildroot
$ git checkout -b 2020.05.1.local 2020.05.1
2.2 创建 helloworld 软件包
1. 编写 helloworld 程序
# 创建helloworld源码
cat > buildroot_external/package/helloworld/src/helloworld.c << 'EOF'
#include <stdio.h>
int main() {
printf("Hello, Lotus Board!\\n");
return 0;
}
EOF
# 创建Makefile
cat > buildroot_external/package/helloworld/src/Makefile << 'EOF'
CC=gcc
CFLAGS=-Wall
helloworld: helloworld.c
$(CC) $(CFLAGS) -o $@ $^
clean:
rm -f helloworld
.PHONY: clean
EOF
2. 创建软件包配置
cat > buildroot_external/package/helloworld/Config.in << 'EOF'
config BR2_PACKAGE_HELLOWORLD
bool "helloworld"
help
Simple Hello World program for Lotus board.
https://example.com
EOF
创建 .mk 文件：
cat > buildroot_external/package/helloworld/helloworld.mk << 'EOF'
################################################################################
#
# helloworld
#
################################################################################
HELLOWORLD_VERSION = 1.0
HELLOWORLD_SITE = $(BR2_EXTERNAL_LOTUS_PROJECT_PATH)/package/helloworld/src
HELLOWORLD_SITE_METHOD = local
define HELLOWORLD_BUILD_CMDS
$(MAKE) CC="$(TARGET_CC)" -C $(@D)
endef
define HELLOWORLD_INSTALL_TARGET_CMDS
$(INSTALL) -D -m 0755 $(@D)/helloworld $(TARGET_DIR)/usr/bin/helloworld
endef
$(eval $(generic-package))
EOF
2.3 创建 lotus 板级支持
1. 创建根文件系统覆盖层
# 创建根文件系统覆盖层结构
mkdir -p buildroot_external/board/lotus/rootfs_overlay/etc
# 创建一个简单的inittab确保helloworld可以运行
cat > buildroot_external/board/lotus/rootfs_overlay/etc/inittab << 'EOF'
::sysinit:/etc/init.d/rcS
::respawn:/sbin/getty -L ttyAMA0 115200 vt100
# 在启动时运行我们的helloworld程序
::once:/usr/bin/helloworld
tty1::respawn:/sbin/getty -L tty1 115200 vt100
EOF
2. 创建后处理脚本
# 创建post-image脚本，用于拷贝生成的镜像
cat > buildroot_external/board/lotus/post-image.sh << 'EOF'
#!/bin/bash
echo "Copying images to project images directory..."
cp ${BINARIES_DIR}/rootfs.tar ${BR2_EXTERNAL_LOTUS_PROJECT_PATH}/../images/lotus-rootfs.tar
cp ${BINARIES_DIR}/zImage ${BR2_EXTERNAL_LOTUS_PROJECT_PATH}/../images/lotus-zImage
echo "Lotus board images ready in ../images/"
EOF
# 给脚本执行权限
chmod +x buildroot_external/board/lotus/post-image.sh
2.3 创建 BR2_EXTERNAL 核心文件
1. 创建 external.desc
cat > buildroot_external/external.desc << 'EOF'
name: LOTUS_PROJECT
desc: Lotus Board Project
EOF
2. 创建 Config.in
cat > buildroot_external/Config.in << 'EOF'
# Main menu for Lotus project external tree
source "$BR2_EXTERNAL_LOTUS_PROJECT_PATH/package/helloworld/Config.in"
menu "Lotus Board Options"
config BR2_LOTUS_ENABLE_DEBUG
bool "Enable debug features"
help
Enable additional debug features for Lotus board.
endmenu
EOF
3. 创建 external.mk
cat > buildroot_external/external.mk << 'EOF'
# Lotus project external makefile
LOTUS_VERSION = 1.0.0
# Add global definitions here
EOF
2.4 创建 Defconfig 配置文件
vim buildroot_external/configs/lotus_defconfig
leo@leo ~/data_4t/github/lotus_bsp
$ cp buildroot/configs/qemu_aarch64_virt_defconfig ./buildroot_external/configs/lotus_defconfig
这里我们默认使用 qemu_aarch64_virt_defconfig 配置
另外需要选择：
# 使用我们的lotus配置
make lotus_defconfig
make menuconfig
Toolchain
Enable C++ support
Host utilities
host cmake
2.5 编译和运行
1. 设置环境并配置
cd ~/lotus_bsp/buildroot
# 设置BR2_EXTERNAL环境变量
export BR2_EXTERNAL=../buildroot_external
# 使用我们的lotus配置
make lotus_defconfig
2. 可选：检查配置
# 检查helloworld包是否已选中
make menuconfig
3. 开始编译
# 开始编译（使用4个线程加速）
make -j4
2.6 测试运行
编译完成后，你可以用QEMU测试（如果选择了支持QEMU的配置）：
系统启动后，你应该能看到输出：
Hello, Lotus Board!
验证 helloworld 程序
在QEMU中或者在实际硬件上运行：
# 手动运行helloworld程序
helloworld
# 输出: Hello, Lotus Board!
这个完整的项目包含了：
项目结构：清晰的目录组织
自定义软件包：完整的helloworld程序包
板级支持：根文件系统覆盖层和后处理脚本
配置系统：通过defconfig整合所有配置
编译运行：完整的编译和测试流程
现在你有一个可以直接运行的基础项目框架，可以在此基础上继续开发更复杂的功能。
