# 项目要求

完成flash启动bootloader并在EMMC上挂载ext4文件系统，将kernel放置在EMMC中

# 1 创建petalinux工程-SD card



1. 加载环境变量

   ```bash
   source /opt/pkg/petalinux/2018.3/settings.sh 
   ```

2. 通过模板创建工程

   ```bash
   petalinux-create -t project --template zynq -n ALIENTEK-ZYNQ
   ```

3. 配置petalinux工程

   ```
   cd ALIENTEK-ZYNQ           //进入到 petalinux 工程目录下 
   petalinux-config --get-hw-description ../hdf/Navigator_7010.sdk/  //导入 hdf 文件 
   ```

4. 配置kernel

   ```
   petalinux-config -c kernel
   ```

5. 配置根文件系统

   ```
   petalinux-config -c rootfs 
   ```

6. 配置设备树文件

   ```
   code project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi
   ```

   ```

   ```

7. 编译工程

   ```
   petalinux-build
   ```

8. 制作BOOT.BIN启动文件

   ```
   petalinux-package --boot --fsbl --fpga --u-boot --force
   ```

9. 将 petalinux 工程目录 image/linux 目录下的 BOOT.BIN 和 image.ub 文件拷
   贝到名为 boot 的分区也即/dev/sdb1 分区中

10. 启动

    ```bash
    run default-bootcmd
    ```

# 2.flash启动bootloader
