除了使用 AArch64 架构的 openEuler 或 CentOS 7/8 运行环境，也可以采用交叉编译的方式编译内核，文档详见 [交叉编译内核](./交叉编译内核.md)。这里，我们在 AArch64 架构的服务器上编译内核。
|
||||
|
||||
### 下载源码
|
||||
### 内核编译
|
||||
|
||||
根据内核不同版本，需要下载不同仓库的不同分支：
|
||||
编译时可能还需要 bison、flex、build-essential 等，根据提示安装即可。
|
||||
|
||||
1. 6.6 内核
|
||||
|
||||
- openEuler 24.09：`git clone git@gitee.com:openeuler/raspberrypi-kernel.git -b OLK-6.6 && cd raspberrypi-kernel`
|
||||
- openEuler 24.03 LTS：`git clone git@gitee.com:openeuler/raspberrypi-kernel.git -b OLK-6.6 && cd raspberrypi-kernel`
|
||||
|
||||
2. 6.1 内核
|
||||
|
||||
- openEuler 23.03：`git clone git@gitee.com:openeuler/raspberrypi-kernel.git -b openEuler-23.03 && cd raspberrypi-kernel`
|
||||
|
||||
3. 5.10 内核
|
||||
|
||||
- openEuler 22.03 LTS SP4：`git clone git@gitee.com:openeuler/raspberrypi-kernel.git -b OLK-5.10 && cd raspberrypi-kernel`

- openEuler 20.09：`git clone git@gitee.com:openeuler/raspberrypi-kernel.git -b openEuler-20.09 && cd raspberrypi-kernel`
|
||||
|
||||
下面编译时可能还需要 bison、flex、build-essential 等，根据提示安装即可。
|
||||
|
||||
### 载入默认配置
|
||||
|
||||
根据内核不同版本，需要载入不同的默认配置：
|
||||
|
||||
1. 6.6 内核
|
||||
|
||||
- openEuler 24.09：`make bcm2711_defconfig`
|
||||
- openEuler 24.03 LTS：`make bcm2711_defconfig`
|
||||
|
||||
2. 6.1 内核
|
||||
|
||||
- openEuler 23.03：`make bcm2711_defconfig`
|
||||
|
||||
3. 5.10 内核

|
||||
- openEuler 22.03 LTS：`make bcm2711_defconfig`
|
||||
- openEuler 21.09：`make bcm2711_defconfig`
|
||||
- openEuler 21.03：`make bcm2711_defconfig`
|
||||
|
||||
4. 4.19 内核
|
||||
|
||||
- openEuler 20.03 LTS：`make openeuler-raspi_defconfig`
|
||||
- openEuler 20.09：`make openeuler-raspi_defconfig`
|
||||
|
||||
对应的 defconfig 文件在 ./arch/arm64/configs 下。
|
||||
|
||||
### 编译
|
||||
|
||||
`make ARCH=arm64 -j4`
|
||||
|
||||
### 创建编译内核模块目录
|
||||
|
||||
`mkdir ${WORKDIR}/output`
|
||||
|
||||
### 编译内核模块
|
||||
|
||||
`make INSTALL_MOD_PATH=${WORKDIR}/output/ modules_install`
|
||||
|
||||
在 ${WORKDIR}/output 文件夹下会生成 lib 文件夹。
|
||||
|
||||
### 收集编译结果
|
||||
|
||||
1. 内核
|
||||
|
||||
`cp ${WORKDIR}/raspberrypi-kernel/arch/arm64/boot/Image ${WORKDIR}/output/`
|
||||
|
||||
2. 设备树文件等
|
||||
|
||||
`cp ${WORKDIR}/raspberrypi-kernel/arch/arm64/boot/dts/broadcom/*.dtb ${WORKDIR}/output/`
|
||||
|
||||
`mkdir ${WORKDIR}/output/overlays`
|
||||
|
||||
`cp ${WORKDIR}/raspberrypi-kernel/arch/arm64/boot/dts/overlays/*.dtb* ${WORKDIR}/output/overlays/`
|
||||
|
||||
至此，所有内核及内核模块相关内容都在 ${WORKDIR}/output 下了。
|
||||
具体编译过程请参考文档 [内核编译](./内核编译.md#内核编译)。

- openEuler 20.03 LTS：`git clone git@gitee.com:openeuler/raspberrypi-kernel.git -b openEuler-20.03-LTS && cd raspberrypi-kernel`
|
||||
- openEuler 20.09：`git clone git@gitee.com:openeuler/raspberrypi-kernel.git -b openEuler-20.09 && cd raspberrypi-kernel`
|
||||
|
||||
## 设置环境变量
|
||||
|
||||
`export ARCH=arm64`
|
||||
|
||||
`export CROSS_COMPILE=aarch64-linux-gnu-`
|
||||
|
||||
## 载入默认配置
|
||||
|
||||
根据内核不同版本，需要载入不同的默认配置：
|
||||
|
||||
1. 6.6 内核
|
||||
|
||||
- openEuler 24.09：`make bcm2711_defconfig`
|
||||
- openEuler 24.03 LTS：`make bcm2711_defconfig`
|
||||
|
||||
2. 6.1 内核
|
||||
|
||||
- openEuler 23.03：`make bcm2711_defconfig`
|
||||
|
||||
3. 5.10 内核
|
||||
|
||||
- openEuler 22.03 LTS SP4：`make bcm2711_defconfig`
|
||||
- openEuler 22.03 LTS SP3：`make bcm2711_defconfig`
|
||||
- openEuler 22.03 LTS SP2：`make bcm2711_defconfig`
|
||||
- openEuler 22.03 LTS SP1：`make bcm2711_defconfig`
|
||||
- openEuler 22.09：`make bcm2711_defconfig`
|
||||
- openEuler 22.03 LTS：`make bcm2711_defconfig`
|
||||
- openEuler 21.09：`make bcm2711_defconfig`
|
||||
- openEuler 21.03：`make bcm2711_defconfig`
|
||||
|
||||
4. 4.19 内核
|
||||
|
||||
- openEuler 20.03 LTS：`make openeuler-raspi_defconfig`
|
||||
- openEuler 20.09：`make openeuler-raspi_defconfig`
|
||||
|
||||
对应的 defconfig 文件在 ./arch/arm64/configs 下。
|
||||
|
||||
## 编译内核
|
||||
|
||||
`make -j9`
|
||||
|
||||
## 创建编译内核模块目录
|
||||
|
||||
`mkdir ${WORKDIR}/output`
|
||||
|
||||
## 编译内核模块
|
||||
|
||||
`make INSTALL_MOD_PATH=${WORKDIR}/output/ modules_install`
|
||||
|
||||
在 ${WORKDIR}/output 文件夹下会生成 lib 文件夹。
|
||||
|
||||
## 收集编译结果
|
||||
|
||||
1. 内核
|
||||
|
||||
`cp ${WORKDIR}/raspberrypi-kernel/arch/arm64/boot/Image ${WORKDIR}/output/`
|
||||
|
||||
2. 设备树文件等
|
||||
|
||||
`cp ${WORKDIR}/raspberrypi-kernel/arch/arm64/boot/dts/broadcom/*.dtb ${WORKDIR}/output/`
|
||||
|
||||
`mkdir ${WORKDIR}/output/overlays`
|
||||
|
||||
`cp ${WORKDIR}/raspberrypi-kernel/arch/arm64/boot/dts/overlays/*.dtb* ${WORKDIR}/output/overlays/`
|
||||
|
||||
至此，所有内核及内核模块相关内容都在 ${WORKDIR}/output 下了。
|
||||
## 内核编译
|
||||
|
||||
具体编译过程请参考文档 [内核编译](./内核编译.md#内核编译)。
|
||||
|
||||
# 验证内核可用性
|
||||
|
||||
使用一个之前刷好 openEuler 树莓派镜像的 SD 卡，直接插到 Linux 主机上，SD 会默认挂载其 boot 分区和 根目录分区。这里其挂载路径分别表示为 ${boot} 和 ${rootfs}，将上面编译好的内核放置到SD卡对应分区。
|
||||
使用一个之前刷好 openEuler 树莓派镜像的 SD 卡，直接插到 Linux 主机上，SD 会默认挂载其 `boot` 分区和 `root` 分区。这里其挂载路径分别表示为 `${boot}` 和 `${rootfs}`，将上面编译好的内核放置到SD卡对应分区。
|
||||
|
||||
## 将内核模块放进rootfs
|
||||
|
||||
`cp -r ${WORKDIR}/output/lib/modules ${rootfs}/lib/`
|
||||
|
||||
## 将内核放进引导
|
||||
|
||||
`cp ${WORKDIR}/output/Image ${boot}/kernel8.img`
|
||||
|
||||
## 将设备树文件放进引导
|
||||
|
||||
`cp ${WORKDIR}/output/*.dtb ${boot}/`
|
||||
|
||||
`cp ${WORKDIR}/output/overlays/* ${boot}/overlays/`
|
||||
内核更新过程请参考文档 [内核更新](./内核编译.md#内核更新)。
|
||||
|
||||
之后，参考 [树莓派使用](./树莓派使用.md) 使用该 SD 卡启用树莓派，验证功能：

# 内核编译
|
||||
|
||||
本文档介绍内核编译和更新的详细过程。操作目录：${WORKDIR}

> **须知：**
|
||||
>当前只有 6.6 版本的树莓派内核同时支持树莓派 5 和树莓派 3B/3B+/4B/400，其他内核版本只支持树莓派 3B/3B+/4B/400。
