No filesystem could mount root,
uboot的bootargs没设置对或者yaffs没有烧写到对应的地方
我觉得如果是写错地方的话用天嵌的烧写程序无论是哪个命令来烧写都会覆盖内核,内核好像都无法启动?如果用错了文件系统的制作程序应该会出现大量的逻辑坏块,这里却看不到。因此楼主很可能在烧写天嵌内核的时候把整个nandflash格式化了,然后把天嵌的内核烧入了nandflash却没有进一步的烧写文件系统。结果校验的时候由于文件系统全部都是FF,所以不会出现大量的坏块,但是入口却没有任何程序。
个人认为楼主应该做一下以下检查:
1、注意制作yaffs文件系统和移植yaffs文件系统驱动是两回事,检查烧入天嵌内核以后是否有烧入文件系统?
2、如果已经移植成功yaffs驱动的话,无论文件系统中的数据是否正确,内核都会启动yaffs来加载文件系统。而且无论使用什么启动参数都应该会显示yaffs Nov 11 2011 20:57:33 Installing. 之类的信息。但是这里却显示No filesystem could mount root,而且没有yaffs Nov 11 2011 20:57:33 Installing. 之类的信息,说明楼主应该根本没移植成功yaffs文件系统驱动。具体为什么没有移植成功只能让楼主自己描述一下移植的过程了。
