zedboard REV .D上移植Linaro所出现问题以及一些观点

本文主要是介绍zedboard REV .D上移植Linaro所出现问题以及一些观点，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

首先，放上成功启动后串口打印信息，方便有需要者自己看一下是卡在哪一步。

Welcome to Linaro 12.11 (GNU/Linux 4.9.0 armv7l)

 * Documentation:  https://wiki.linaro.org/

至此，系统启动完成。

说一下其中的一些问题，

1，如果卡在init: ureadahead main process (***) terminated with status 5 这类地方进不了系统，首先得明确你的引导boot.bin文件基本没有什么问题，是在linux内核启动过程中卡住，这个时候建议重新生成一下文件目录。

2，前面启动过程中有直接卡在某处，然后图形输出为两只linux企鹅，个人认为可能是Image镜像文件不匹配之类，建议重新生成。

具体操作指南：（感谢众多大神经验分享）
