I need the basic information and technical knowledge about ARM's start 
up file.
 I want to write my own crt0.s file for my project, so how can I start.
 I would like to know that are there any tutorials available?

regards.

You can get the basic information in section 10.3 here:
http://www.arm.com/pdfs/sdt250usrman.pdf

This information is specific to ARM's SDT2.5 toolset and only covers
the ARM7 core itself, but it may be a helpful starting point?

Check out:

Highly recommended: it gives a step-by-step series of examples of 
everything you need for a basic startup.

Look in the files area for: gcc_and_ucosii.zip

or access it at:

http://www.ovro.caltech.edu/~dwh/ucos/project_AR1803.pdf
http://www.ovro.caltech.edu/~dwh/ucos/gcc_and_ucosii.zip

It shows how to write the startup code. It'll help you interpret
the startups from say Keils free tools, or the FreeRTOS examples.
