Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Why cramfs can mount, but kernel show "No init found"?
everybody, I maked a new linux-kernel for my s3c2440, kernel is well, but I don't what error in my this step. I use cramfs for rootFS, it can mount (I think), because I see in Debug-Info "VFS: Mounted root (cramfs filesystem) readonly", and go on to show "No init found".
what can I do in this error, Please help me!

The cramfs is the "armbase" - this is what your mtdparts partition must reflect. Currently you are giving the mtd partition an offset of 0x1c0000 from the start of the armflash.0 device. As your memory list shows, the offset is actually 0x200000. So change your command line to:
