No, he doesn't.
But he knows where to ask: www.lmgtfy.com
sir, i didn't get the proper information from the link u gave so kindly support how to port linux on ARM 9 LPC2929
The documentation that you require to tell you how to perform a Linux port is called a "Porting Guide".
The search link gives you links to plenty of Porting Guides - so what, exactly, is it that you require?
Note that performing a Linux port is not a trivial or beginners task - you need to have a deep understanding of the Linux kernel, and a good understanding of your target hardware, and very good 'C' skills...
Isn't it rather obvious that "i need the steps to port the os" means: "where can I downloaded an already ported version"?
Otherwise, the message would probably have been "I have tried to port Linux to xxx but am currently stuck getting xxx to work - anyone have any idea?"
sir, thanks for your reply sir...
