petalinux-bulid 编译报错，设备树camera_in_axi_gpio_0问题

baymaxzhuwei

按照教程《领航者ZYNQ之嵌入式Linux开发指南_V3.3》中 “第八章 Linux显示设备的使用”中逐步创建Linux镜像。
使用资料中的 “ZYNQ领航者\vivado_prj\Navigator_7020”中的xsa创建，然后使用 “资源文件\出厂镜像相关\”里的linux内核中的navigators-system-suer.dtsi替换petalinux工程中的system-suer.dtsi。最终使用petalinux-build。
编译报错信息：

定位问题是设备树文件中：“camera_in_axi_gpio_0” 这个没有定义？ 这个完全按照教程中进行为什么会报错呢。请问如何解决

1. &i2c2 {
   
2.         clock-frequency = <100000>;
   
3. 
   
4.         ov5640@3c {

把camera_in_axi_gpio_0改成camera_in_axi_gpio_1就行了
