+# raspberrypi-kernel
+
+#### Description
+
+The openEuler-1.0-LTS kernel for running on Raspberry Pi, located at branch [openEuler-1.0-LTS-raspi](https://gitee.com/openeuler/raspberrypi-kernel/tree/openEuler-1.0-LTS-raspi/).
+
+This repository is built based on [openEuler-1.0-LTS kernel](https://gitee.com/openeuler/kernel/tree/openEuler-1.0-LTS/) and [Raspberry Pi kernel](https://github.com/raspberrypi/linux/tree/rpi-4.19.y).
+
+#### Architecture Requirements
+
+Hardware: Raspberry Pi 3B/3B+/4B.
+
+Architecture: AArch64.
+
+#### Compiling
+
+Compile kernel and kernel modules.
+
+1.  Prepare compile environment
+
+OS: openEuler or Centos 7/8;
+
+Architecture: ARM.
+
+For example, you can use [QEMU](https://www.qemu.org/) to build ARM system emulation.
+
+2.  Download source
+
+`git clone https://gitee.com/openeuler/raspberrypi-kernel.git`
+
+3.  Go to the source directory and checkout the openEuler-1.0-LTS-raspi branch
+
+`cd raspberrypi-kernel`
+
+`git checkout -b openEuler-1.0-LTS-raspi origin/openEuler-1.0-LTS-raspi`
+
+4.  Load default settings
+
+`make openeuler-raspi_defconfig`
+
+5.  Compile kernel
+
+`make ARCH=arm64 -j4`
+
+6.  Create directory for compiling kernel modules
+
+`mkdir ../output`
+
+7.  Compile kernel modules
+
+`make INSTALL_MOD_PATH=../output/ modules_install`
+
+Now, the kernel compilation is complete.
+
+#### Installation
+
+Refer to `https://gitee.com/openeuler/raspberrypi` for details about how to use this compiled kernel to build openEuler image for Rasberry Pi.

+
+#### 介绍
+
+适用于树莓派的 openEuler-1.0-LTS 内核源码，位于本仓库分支：[openEuler-1.0-LTS-raspi](https://gitee.com/openeuler/raspberrypi-kernel/tree/openEuler-1.0-LTS-raspi/)。
+
+本仓库基于 [openEuler-1.0-LTS 内核](https://gitee.com/openeuler/kernel/tree/openEuler-1.0-LTS/) 和 [树莓派内核](https://github.com/raspberrypi/linux/tree/rpi-4.19.y)。
+
+
+#### 硬件要求
+
+硬件：树莓派 3B/3B+4B。
+
+架构：AArch64。
+
+#### 编译
+
+编译内核和内核模块。
+
+1.  准备编译环境
+
+操作系统：openEuler 或 Centos 7/8；
+
+架构：ARM。
+
+可以使用 [QEMU](https://www.qemu.org) 模拟器搭建 ARM 运行环境。
+
+2.  下载源码
+
+`git clone https://gitee.com/openeuler/raspberrypi-kernel.git`
+
+3.  进入源码目录并切换到openEuler-1.0-LTS-raspi分支
+
+`cd raspberrypi-kernel`
+
+`git checkout -b openEuler-1.0-LTS-raspi origin/openEuler-1.0-LTS-raspi`
+
+4.  载入默认设置
+
+`make openeuler-raspi_defconfig`
+
+5.  编译内核
+
+`make ARCH=arm64 -j4`
+
+6.  创建编译内核模块目录
+
+`mkdir ../output`
+
+7.  编译内核模块
+
+`make INSTALL_MOD_PATH=../output/ modules_install`
+
+至此，内核编译完成。
+
+#### 使用说明
+
+利用上面编译好的内核来构建镜像，具体文档参见`https://gitee.com/openeuler/raspberrypi`。
