首先需要使用与petalinux相同版本的vivado创建工程，与之前不同的是在创建硬件设计时需要勾选上添加bit文件，所以要在生成bit文件之后再创建硬件设计文件

打开装有对应版本的linux系统，设置petalinux的环境变量，在petalinux的安装目录中找到settings.sh，使用下面这条命令设置环境变量

source ./settings.sh

创建petalinux工程相关的命令我都会提供在工程目录的file文件夹中

创建petalinux工程，demoname为工程名称

把在vivado中创建的硬件配置文件，复制到上面的工程文件中

进入到工程目录中，配置petalinux

配置不作修改，摁右箭头选择Exit点击enter保存退出

等待配置完成后编译项目

修改设备树

设备树的内容如下，文件我也会放在file文件夹中
