Could you be a little bit more specific what you need help with? There 
are plenty of books, tutorials and other documents about ARM 
programming. See http://embdev.net/topic/129986#new for a few starting 
points.

Hi I have uploded the schematic of my Dev board on my enips account as 
it was 4.4 MB and i could not attached over here.
here is the link
{getting error in upload, I will upload that ASAP}
As you asked mt what kind of help I need, I m try to specifying it over 
here.
I know C, and have just idea about the Assembly, As I m studying it side 
by side now.
But I have no idea that I have board infront of me connect to my 
computer how should I start, what should I do.
As someone told me that I need to flash the startup code, then install 
boot loader, and then operating system, as it my board got very less mem 
size, so I need install Ucos on it. only after that I will able to write 
drivers for available devices..
But as i don't know what should be my first stepping stone, I m clueless 
that where should I go.
I try to put my effort to move, after a week I find that I m just moving 
in the Circle..
I just want a little favor to community that please tell me where to go, 
What to read. I will put myself and do all.
I will love if you are so kind and having watch on me, I know this could 
be a over kill of your kindness but the only way to track where I m 
going.
I know here, plenty of people for whom the task, which seems to me like 
mount everest is like a part of send, their just five minute will be a 
gr8 lesson for me..
I request that if you can spend little time on my problem..
Thanks
Akki

First you will need a bootloader (lpc21isp) and a compiler (WinARM). 
Don't start with ucOS or another operating system, start with a simple 
standalone example program. Martin Thomas has some for LPC2129 on his 
website (see link I gave you above). That's really all you need to get 
started, but you have to give yourself some time, don't expect to 
understand everything within a few hours.
