标题: 关于linux2.6.14.7在at91rm9200上启动的问题
小弟第一次在9200dk上移植linux2.6.14.7的系统，出现了以下现象，且从bootloader不停重启整个系统

我制作的过程是：下载linux2.6.14.6源码和补丁：patch-2.6.14.6和patch-2.6.14.7以及9200的补丁：2.6.14－at91.patch.编译器用的是：3.4.1的。
不知什么原因出现了以上错误，望大侠们指点下，谢谢！

AT91F_LowLevelInit(): Debug channel initialized

你用了这个函数?

作者: audi78 时间: 2006-12-18 09:36
没有用这个函数。
运行到这里，终端出现的，然后马上从bootloader开始重新启动，运行到内核后，出现这个函数后重启，反复如此。不知那里出现了问题。
