linux根文件系统与initrd
1 根文件系统
简单来说,(根文件系统)就是系统第一个mount的文件系统
Filesystem Handling
Like every traditional Unix system, Linux makes use of a system 's root filesystem : it is the filesystem that is directly mounted by the kernel during the booting phase and that holds the system initialization scripts and the most essential system program.
Other filesystems can be mounted either by the initialization scripts or directly by the users on directories of already mounted filesystems. Being a tree of directories every filesystem has its own root directory. The directory on which a filesystem is mounted is called the mount point. A mounted filesystem is a child of the mounted filesystem to which the mount point directory belongs. For instance, the /proc virtual f

前段时间为了解决一个从128M升级到256M的DDR问题,搞的是焦头烂额。最后在别人讨论的情况下终于试出来了正确结果,下来还得自己总结下。
自己的硬件平台才采用的是6410的DMC1即32位的DRAM控制器,两个16位128M的DDR的地址线是共在一起连在6410的16根地址线 ......
