内核加载文件系统失败？（帮顶有分）
来源: 互联网 发布时间：2016-07-03
本文导语: 我在配置内核时，设置initrd，并且设置了文件系统路径，因此生成的内核镜像，还包括了一个文件系统在里面。 我的启动脚本是： set serverip 192.168.1.11; set ipaddr 192.168.1.12; set bootargs root=/dev/ram rw ip=192.168.1.12::::...
我在配置内核时，设置initrd，并且设置了文件系统路径，因此生成的内核镜像，还包括了一个文件系统在里面。
我的启动脚本是：
set serverip 192.168.1.11;
set ipaddr 192.168.1.12;
set bootargs root=/dev/ram rw ip=192.168.1.12::::motfcc0:off console=ttyS1,115200
tftp 0xf00000 cdma-cpio.dtb
tftp 0x500000 uImage
bootm 0x500000 - 0xf00000
结果启动内核的时候，到了VFS文件系统加载，就出问题了(前面的打印信息供参考，主要是最后一句）:

这个没错的哇，我们基本都这么写的，不知道是不是initrd要设一下的
我们一般的bootargs 是console=ttyS0,115200n8 initrd=2g,1 root=/dev/ram

会不会是硬盘驱动问题
现在硬盘都是串口的，所以内核要配置SATA那块
