Linux 在AT91RM9200上运行出现错误

金水岸边

     把系统映像文件和文件系统烧写到FLASH之后，复位，系统能启动，但是在运行过程中出现了问题，我看不懂什么意思，请大侠们帮着瞅瞅！先行谢过！

     运行的全部结果如下：

请问其中标为红色的几个错误什么意思？系统运行失败是什么原因引起的？

存储映射有问题么？什么版本的内核？

liugang9931706

兄弟，昨天我刚把这个搞过。我升级内核刚完成，中途没有遇到过这个问题。不过我看了下你的U-boot信息：
Kernel command line: root=/dev/ram rw initrd=0x21100000,60000000 ramdisk_size=15
360 console=ttyS0,115200 men=32M
60000000这个设置有没有问题？men应该是mem吧？

金水岸边

你真细心，万分感谢！

金水岸边

2.4.19的内核，我是新手，很多基本问题都得请教高手，谢谢了！

金水岸边

请问你是怎么跑通的，我把men改成mem之后，运行结果是一样的。

金水岸边

问题已经解决，是环境变量设置时马虎大意了，把“bootargs root=/dev/ram rw initrd=0x21100000，6000000 ramdisk_size=15360 console=ttyS0，11520 mem=32M”中的6000000写成60000000了（多了一个零），所以出现“initrd (0x21100000 - 0x24a38700) extends beyond physical memory - disabling initrd”错误，但愿我的经验对各位能有所帮助，别再犯这类错误。
