+## 编译 A311D U-Boot
+
+1.  下载源码
+
+    1. 下载 U-Boot 源码
+
+        ```
+        git clone --depth=1 https://github.com/u-boot/u-boot.git -b v2025.10
+        ```
+
+    2. 下载 U-Boot 打包工具
+
+        ```
+        git clone --depth=1 https://github.com/LibreELEC/amlogic-boot-fip.git
+        ```
+
+2.  编译 U-Boot
+
+    1.  配置 U-Boot
+
+        ```
+        cd u-boot
+        make ARCH=arm khadas-vim3_defconfig
+        ```
+
+        如果需要自定义 U-Boot 功能
+
+        ```
+        make ARCH=arm menuconfig
+        ```
+
+    2.  编译 U-Boot
+
+        ```
+        make ARCH=arm -j$(nproc)
+        ```
+
+3.  运行 U-Boot 打包脚本
+
+    如果是 `aarch64` 架构的构建主机，运行之前需要安装 `qemu-user` 软件包：
+    
+    - Debian/Ubuntu 安装命令如下；
+
+        ```
+        sudo apt-get install qemu-user
+        ```
+
+    - openEuler 25.09 安装命令如下：
+
+        ```
+        sudo dnf install qemu-user
+        ```
+
+    - 其他 openEuler 版本安装命令如下：
+
+        ```
+        wget https://repo.openeuler.openatom.cn/openEuler-25.09/everything/aarch64/Packages/qemu-user-8.2.0-47.oe2509.aarch64.rpm
+        wget https://repo.openeuler.openatom.cn/openEuler-25.09/everything/aarch64/Packages/qemu-user-binfmt-8.2.0-47.oe2509.aarch64.rpm
+        rpm -ivh qemu-user-8.2.0-47.oe2509.aarch64.rpm
+        rpm -ivh qemu-user-binfmt-8.2.0-47.oe2509.aarch64.rpm
+        ```
+
+    U-Boot 编译完成后，运行以下命令来打包 U-Boot
+
+    ```
+    cd ../amlogic-boot-fip
+    mkdir ../output
+
+    ./build-fip.sh khadas-vim3 ../u-boot/u-boot.bin ../output
+    ```
+
+    运行以上命令后，输出如下：
+
+    ```

+4.  收集编译结果
+
+    将生成的 u-boot.bin.sd.bin 文件复制到工作目录。
+
+    ```
+    cp ../output/u-boot.bin.sd.bin $WORKDIR
+    cd $WORKDIR
+    ```
