 # raspberrypi-kernel
 
 #### Description
-Kernel of Raspberry Pi
+
+Kernel Image of Raspberry Pi.
+
+The `kernel.tar.gz` is from <https://gitee.com/openeuler/raspberrypi-kernel>. After you put your public ssh key into your account in gitee, you can obtain `kernel.tar.gz` by executing command `. SOURCE`. You can directly use the `kernel.tar.gz` in this repository instead.

+1. The version of raspberrypi kernel ends with `.raspi`, e.g., `4.19.90-2005.2.0.0036.raspi.aarch64 `.
+2. The module files will be installed into `/lib/modules`. The directory name of these module files is the same as the version of raspberrypi kernel, such as `4.19.90-2005.2.0.0036.raspi.aarch64`.
+3. The image file will be installed into `/boot`, whose filename is like `vmlinuz-4.19.90-2005.2.0.0036.raspi.aarch64`. Note that the image file is in GZ compression format by default. You can decompress this  file, and then rename it to `kernel8.img` as follows.
+
+    ```
+    cd /boot
+    cp vmlinuz-4.19.90-2005.2.0.0036.raspi.aarch64 Image.gz
+    gunzip Image.gz
+    mv Image kernel8.img
+    ```
+
+4. The device tree files will be installed into `/boot`. The directory name of these files looks like `dtb-4.19.90-2005.2.0.0036.raspi.aarch64`. You need to copy the device tree files to `/boot` as follows.
+
+    ```
+    cd /boot
+    cp dtb-4.19.90-2005.2.0.0036.raspi.aarch64/*.dtb ./
+    ```

 #### 介绍
-Kernel of Raspberry Pi
+
+Raspberry Pi 内核映像文件。
+
+`kernel.tar.gz` 来自 <https://gitee.com/openeuler/raspberrypi-kernel> 仓库，将 SSH 公钥添加到 gitee.com 的账户中后，可通过执行 `. SOURCE` 来获取 `kernel.tar.gz`。也可以采用本仓库通过 Git LFS 上传的 `kernel.tar.gz`。

-3.  xxxx
+安装 raspberrypi-kernel 后，
+
+1. 内核版本号后缀增加 `.raspi` 标识，形如 `4.19.90-2005.2.0.0036.raspi.aarch64`。
+2. 内核模块安装在 `/lib/modules` 目录下，对应文件夹名称同内核版本号，如 `4.19.90-2005.2.0.0036.raspi.aarch64`。
+3. 内核映像文件在 `/boot` 目录下，映像文件名形如 `vmlinuz-4.19.90-2005.2.0.0036.raspi.aarch64`。注意，该文件默认是采用 GZ 压缩格式的压缩文件，需要解压缩后重命名为 `kernel8.img`。
+
+    具体过程：
+    ```
+    cd /boot
+    cp vmlinuz-4.19.90-2005.2.0.0036.raspi.aarch64 Image.gz
+    gunzip Image.gz
+    mv Image kernel8.img
+    ```
+
+4. 设备树文件在 `/boot` 目录下的文件夹下，该文件夹名称形如 `dtb-4.19.90-2005.2.0.0036.raspi.aarch64`，需要将其中的设备树文件拷贝到 `/boot` 目录下。
+
+    具体过程：
+    ```
+    cd /boot
+    cp dtb-4.19.90-2005.2.0.0036.raspi.aarch64/*.dtb ./
+    ```
