petalinux iamge文件生成和启动后，如何进一步编写应用软件

petalinux iamge文件生成和启动后，如何进一步编写应用软件，以及以后的下载和调试方式是怎样的一个过程啊？？？

编写应用程序可以在linux下使用petalinux-new-app命令来添加应用程序。
可以看一下以下网址的内容：
http://www.petalogix.com/resources/documentation/petalinux/userguide/Customising/UserApps

这个UserApps 说明很不详细啊
应用程序写完后在那设置下，使程序在系统启动时启动啊？？？

按照步骤做后，生成image文件下载即可，需要调用时可以之间键入名称，就可以运行所编写的应用程序。

我按照网站的步骤，先petalinux-new-app helloworld，未作任何的改动再make出现如下错误
